Question AXION GLUON MATTER AS DARK MATTER

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 .

Hello Mr T
It seems you know more than most.
Maybe we can learn from you.

Axion coupling theoretical in a Chiral motion.
Yes, Axions are theoretical.
Yet! we look at various theories and their probable properties.

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.
