No Harry. I hate to have tell you, you only too obviously described mass matter observations from a viewpoint outside-in, not inside-out. Universes, and all they are, are very, very different entities inside-out from what they are outside-in. Holes, voids, vacuums, vector gravitationally opening systems (inversely squaring fractal zooms structure of universe) to infinities, from the inside-out.

 

[Harry Costas]

I see it from a different point of view so to speak.

You have to be inside the condensate to understand its properties.

Just seeing the effects does not explain how it comes about.

One more thing there is only one Universe.

 

[Harry Costas]

We need to understand the internal workings of condensates to understand their properties and the resultant images created by their vortices.

GALPs! Composite heavy axion-like Dark Matter​

Pierluca Carenza, Roman Pasechnik, Zhi-Wei Wang

We propose a novel class of Dark Matter (DM) candidates in the form of a heavy composite Axion-Like Particle (ALP) with highly suppressed electromagnetic interactions, being stable even for masses exceeding the GeV scale. We argue that such a composite ALP emerges as a bound state -- the dark glueball -- due to confinement in a pure Yang-Mills dark sector. In a minimal ultraviolet complete QCD-like model, cosmological production of dark gluons as well as photons occurs via heavy fermion annihilation which effectively reheats both the dark and visible sectors setting up their temperature scales. Furthermore, effective interactions between glueballs and photons, resembling those of standard ALPs, are radiatively generated by heavy fermion loops. Consequently, DM glueballs interacting with photons are dubbed `Glueball ALPs' (GALPs). We uncover novel phenomenology of GALPs focusing on their unique astrophysical and cosmological signatures.

Axion Gluon Matter may be confined by Partonic and or by Quark matter, to confine Quark matter by Neutron matter.
To confine Axion Matter under lab conditions is probably impossible for now.

Axion Icebergs: Clockwork ALPs at hadron colliders​

Srimoy Bhattacharya, Debajyoti Choudhury, Suvam Maharana, Tripurari Srivastava

The conventional ultralight QCD axion is typically rendered invisible at collider experiments by its large decay constant. What could also hint at its possible existence is the observation of other (heavy) particles that are characteristically related to the light axion. One such scenario is afforded within the framework of the clockwork mechanism where the axion can have suppressed couplings with the gluons or photons while its companion axion-like particles (ALPs) have relatively unsuppressed couplings. We study a minimal clockwork model for the QCD axion invoking a KSVZ-like setup and examine the visibility of the ALPs (an) at the LHC through the process pp→an(+additionaljets), an→γγ. The model contains N ALPs with a decay constant f and masses defined by a scale m characteristic of the nearest-neighbour interactions of the scalar fields. For 10≲m≲100 GeV, f∼1 TeV and N∼O(10), the full spectrum of ALPs is accessible and the corresponding diphoton invariant mass distribution comprises a unique signature of a wide band of resonances. For the case of light ALPs (m∼O(10GeV)) with the axion being a dark matter candidate, the mass-splittings among the former are so small that the signal profile mimics that of a single broad resonance, or an axion iceberg. The effect subsides for heavier ALPs, albeit still exhibiting undulating peaks. For light ALPs, the scenario is imminently testable by the end of LHC's Run 3 phase, with the estimated cumulative significance reaching the discovery threshold for an integrated luminosity of ∼300fb−1. While the signals for the heavier ALPs in this minimal setup may not be as prominent within the ongoing LHC operation, one could expect to probe a wider parameter space of the model at the forthcoming HL-LHC.

 

[Thermoman]

The question whether Axion Gluon matter could be Dark Matter, is worth reaching. Other threads relating to this topic are worth reading.

Science never ceases to amaze me ! The question is whether something written could be something written !

Other threads , can I be sarcastic ? Are these other threads Harry Potter and Pepper Pig ?

This forum has a fiction section ?

Why does science accept so much garbage science ?

 

[Harry Costas]

That''s very interesting from a non-scientist.

By definition anybody who studies and/or practices science is a scientist. The only difference between an amateur scientist and a professional scientist , is that an amateur scientist doesn't get paid a salary , it is not their job . This doesn't mean the amateur lacks knowledge or can't make premise for debate!
FYI I have studied on many science forums , spent a lot of time on Cambridge science forum and others learning science. I started about 2009 so have a learnt a lot of things over time . I'm still learning , do we ever stop ?

We can speculate different particles all day long but without physical proofs they are really kind of meaningless . We haven't even really proved Quarks exist etc yet because they are just too small to observe at this moment in time . In years to come no doubt somebody will invent super magnification and we'll be able to see more .

To be honest though I like the name Gluon , would be great to call spaces conserved point energy Gluons because they are as if Glued to the points by inertia .

Split Cherenkov radiation in isotropic chiral matter​

Eduardo Barredo-Alamilla, Luis F. Urrutia, Maxim A. Gorlach

Chiral matter exhibits unique electromagnetic responses due to the macroscopic manifestation of the chiral anomaly as anomalous transport currents. Here, we study the modification of electromagnetic radiation in isotropic chiral matter characterized by an axion coupling that varies linearly over time θ(t)=b0t. Using Carroll-Field-Jackiw electrodynamics, we derive the causal Green's function to investigate the stability and radiation properties of the system. Even though the plane-wave modes of isotropic chiral matter exhibit imaginary frequencies for long wavelengths, which might suggest instability in the system, we show that their contribution is confined to the near-field region. Also we find no exponentially growing fields at arbitrarily large times, so that stability is preserved. Under these conditions the radiation yields a positive energy flux, although this is not an inherent property of the general definition. In the case of a fast-moving charge, we confirm the existence of vacuum Cherenkov radiation and show that, for refractive indices n>1, the Cherenkov cone can split into two concentric cones with opposite circular polarizations. This split, governed by the speed of the particle v, n and b0, resembles the optical spin-Hall effect and offers potential applications for creating circularly polarized terahertz (THz) light sources. Our Green's function approach provides a general method for analyzing radiation in chiral matter, from Weyl semimetals to quark-gluon plasmas, and can be extended to systems such as oscillating dipoles and accelerated charges.

Glueball Axion-Like Particles​

Pierluca Carenza, Roman Pasechnik, Zhi-Wei Wang

Dark Yang-Mills sectors that confine to form stable composite states, known as glueballs, have been traditionally proposed as a potential explanation for cosmological Dark Matter (DM). Earlier studies have established viability of the lightest scalar glueball as a possible DM candidate. In this work, we explore a whole class of effective composite sectors in the confined Yang-Mills regime featuring an additional pseudoscalar glueball state. We also investigate the role of effective interactions of the dark glueball sector with the visible sectors via higher-dimensional operators primarily focusing on dimension-8 couplings of glueballs to photons and gluons. We stress the remarkable similarities between the phenomenology of such glueball effective theories and Standard Model extensions featuring Axion-Like Particles (ALPs). Hence, one deals with a new class of composite Glueball ALPs (or GALPs) coupled to photons and/or nucleons in a wide mass range, from sub-eV to the Planck scale, yielding viable DM candidates that can be probed by astrophysical and cosmological observations.

Axion strings from string axions​

James M. Cline, Christos Litos, Wei Xue

A favored scenario for axions to be dark matter is for them to form a cosmic string network that subsequently decays, allowing for a tight link between the axion mass and relic abundance. We discuss an example in which the axion is protected from quantum gravity effects that would spoil its ability to solve the strong CP problem: namely a string theoretic axion arising from gauge symmetry in warped extra dimensions. Axion strings arise following the first-order Randall-Sundrum compactification phase transition, forming at the junctions of three bubbles during percolation. Their tensions are at the low scale associated with the warp factor, and are parametrically smaller than the usual field-theory axion strings, relative to the scale of their decay constant. Simulations of string network formation by this mechanism must be carried out to see whether the axion mass-relic density relation depends on the new parameters in the theory.

Mass and Force Relations for Extremal EMDA Black Holes​

Sera Cremonini, Mirjam Cvetic, Christopher N Pope, Aritra Saha

We investigate various properties of extremal dyonic static black holes in Einstein-Maxwell-Dilaton-Axion theory. We obtain a simple first-order ordinary differential equation for the black hole mass in terms of its electric and magnetic charges, which we can solve explicitly for certain special values of the scalar couplings. For one such case we also construct new dyonic black hole solutions, making use of the presence of an enhanced SL(2,R) symmetry. Finally, we investigate the structure of long range forces and binding energies between non-equivalent extremal black holes. For certain special cases, we can identify regions of parameter space where the force is always attractive or repulsive. Unlike in the case without an axion, the force and binding energies between distinct black holes are not always correlated with each other. Our work is motivated in part by the question of whether long range forces between non-identical states can potentially encode information about UV constraints on low-energy physics.

Searching for axion-like particles with SPHEREx​

Marco Regis, Marco Taoso, Jorge Terol Calvo

We study prospects to detect axion-like particles (ALPs) with the upcoming near-infrared telescope SPHEREx. The signal under investigation is the ALP decay into two photons. Assuming dark matter (DM) to be in the form of ALPs, we analyze the signal from the DM halos of dwarf spheroidal galaxies, the Large Magellanic Cloud and the Milky Way. We find that SPHEREx can significantly improve current limits on the axion-photon coupling in the 0.5-3 eV ALP mass range.
