This 'charming' particle could have saved the universe

Physicists at the Large Hadron Collider obtained the result by analyzing over 30.6 million particle decays, and are aiming to look with more precise detectors when the atom smasher powers up again in September.

The report says "Some hypotheses suggest that particles like the charm meson could have saved the material universe from annihilation — especially if they transition from antimatter to matter more often than they go the other way."

The arXiv paper link provided is a 20 page report. It is unclear to me where this origin explanation fits in with current BB model and inflation epoch. Alan Guth provides inflation scale 10^-53 m to 1 m size today, Quantum Fluctuations in Cosmology and How They Lead to a Multiverse, https://ui.adsabs.harvard.edu/abs/2013arXiv1312.7340G/abstract, December 2013.

My observation. Alan Guth in the paper says " From the end of inflation to today the universe would expand by another factor of ∼ 10^15 GeV/3K ≈ 10^27. This means that a distance scale of 1 m today corresponds to a length of only about 10^−53 m at the start of inflation, 18 orders of magnitude smaller than the Planck length (∼ 10^−35 m)." That is something to ponder 10^-53 m and now the universe expanded to some 93 billion light years in diameter, https://phys.org/news/2021-03-myths-big.html, Five myths about the Big Bang 22-Mar-2021, "That which we call the observable universe is a bubble surrounding us that is 93 billion light-years in diameter."

So applying the scale where 1 meter today = 10^-53 m at the start, we have the universe begin ~ 8.8 x 10^-27 m size and expand to ~ 8.8 x 10^26 m size today in 13.8 billion years, ~ 4.352 x 10^17 seconds. Space and time expands by some 10^53 order of magnitude or more to create the universe we see today, quite a cauldron at the start.

Just where in this origin story do the charm mesons fit that allows matter to form and be stable like the life of an electron or proton? It would be good to see a plain language statement on when did these particles appear and rescue the universe from destruction, as well as that universe size compared to the present, 93 billion light years in diameter according to BB model.

Yes. Smaller than the Planck time limit things become suppositional. Those who favor the singularity idea, 10^-53 is huge compared to 0.

IMO, they think the switch from antimatter to matter should be more often, and that this muon may be demonstrating this critically important imbalance, at least it may be a start down a path that seems obvious.

When did this switch from antimatter to matter take place in the BB model? Inflation starts 10^36 s after BB and the universe using Alan Guth scaling cited in post #2 shows the universe in the 10^-27 m size. As post #3 states, *at least it may be a start down a path that seems obvious."

Interesting how what *seems obvious* in the BB model without defining when or even the universe size when antimatter switched to matter and evolved into the stable electron mass and lifetime as an example. That thinking may seem obvious to some but not to me.

The switching “more often” to matter from antimatter is the key to understanding what is obvious; the Universe is comprised of matter, not anti-matter. This is true if one holds the hypothesis that both emerged in the first tiny fraction of the first second.

The strength of BBT is found in what we can actually observe today, not the time before or during the first Planck time unit.

Helio, good comment in post #5. My concern is simple. Observing particle collisions in the present in labs is testable and good, but not the same as BB model initial conditions. Very different vacuum energy density, temperature, and 3D space expansion rate(s) where volume, density, and temperatures change dramatically in a brief time slice. This could alter everything about matter abundance seen in the universe today.

Agreed. The extreme lab circumstances is also an indication as to how difficult it is to discover much. But the news is that we are getting some bits of direct evidence that may help support the hypotheses that claim there was some sort of asymmetry between matter anti-matter formation due to likely differences between which switched more often.

What would be really cool would be to discover why matter is favored. I don't know if there are any hypotheses yet for this.
