For the first time the large accelerator in Geneva measured "temporal asymmetry" between matter and antimatter. Although the standard model may explain the phenomenon, the discovery is another way to measure the imbalance between the particles and hopefully also to predict new physics
One of the great puzzles in physics is the excess of matter in the universe over antimatter. The breaking of the balance implies that the laws of nature dictate different behavior between matter and antimatter. The standard model, which describes the physics laws of the particles in nature, explains the asymmetry with the help of "CP breaking". If we change the charge sign of the material and reflect it in space (Parity), it will behave differently in relation to its corresponding antimatter (and in the same way also in relation to the transformation done on the antimatter). When symmetry is broken physicists learn that an imbalance is created between the two particles, but despite the elegant mechanism the phenomenon predicts a weak imbalance rather than a clear dominance of matter over antimatter. To this day the mystery remains open and we do not have a proven mechanism that explains the imbalance that started from Genesis.
CP breakage was first discovered five decades ago in the K scale0 And later also in 2001 in food B0 and in other particles. The break was also observed in the last report of the research team at the LHCb Shesran in the D scale0. Physicists can observe the phenomenon in one of two ways: the decay ratio of a certain particle to another particle can be different in relation to the antiparticle equivalent, or in the second method known as "time-dependent asymmetry" which is expressed in the change of the particle's lifetime. The change in lifetime results from spontaneous oscillations that the particle makes between itself and its antiparticle counterpart.
symmetry breaking
Until now, the breaking of the symmetry was only observed through the anomaly in the amount of decay, but at the 19th conference held in Sarn regarding the "Beauty" or "Bottom" b quark, the LHCb research team reported for the first time a "temporal asymmetry ” between the matter and antimatter in the B scales0 consisting of an s quark and a b antiquark, when it decayed to the -K scale. The researchers collected the data from the first and second runs of the large accelerator and obtained a statistic of 6.7 sigma, far beyond the required (5 sigma). The spokesperson for LHCb adds that "the cycle time of the oscillation between matter and antimatter for the balance Bs0 It is about three thousand billion times per second, but despite the enormous speed, the high resolution of the detectors allowed the researchers to locate and measure the effect. The first observation of temporal asymmetry is a milestone in the search for the difference between matter and antimatter."
As a next step, as reported in the release, the research team plans to compare the latest measurements with previous measurements of CP breakage to understand how well they match the standard model. Only after such a comparison will researchers be able to know whether new physics has been discovered that may hint at an unknown process that broke the imbalance between matter and antimatter from the beginning of the universe.

Yosef is an average reader even if he likes knowledge
And science has a hard time understanding the complex terms
that appear here
That's why the few responses
blah blah blah blah blah blah blah blah blah blah blah blah
The more you discover, the less you understand. I think we will never know the answer.
The structure of the universe continues to be mysterious and incomprehensible, and the question of what is matter has never been answered.
The concept of force continues to star in theoretical physics, even though it is seen as a meaningless phrase.
Time remains the great disappearance, and it is not at all understood how light moves in empty space.
Theoretical physics has been stuck in place for 100 years, and it's time to wake it up.
The state of wakefulness will be created by a new concept of passive time.
A wonderful new universe - for you to judge
The two fundamental concepts in the Newtonian universe are force and matter
The two fundamental concepts in the Einsteinian universe are energy and matter
The two fundamental concepts in the neural universe are energy and passive time.

Dear Joseph,
Definitely possible. There are many mechanisms for breaking symmetry. Symmetry breaking can occur spontaneously or can occur when an actual change is made to the model. I would say that the more interesting question is in which processes a spontaneous break occurs in a model in which the symmetry apparently exists. As far as we know, the mechanism hides in temperature and the symmetry tends to decrease as the universe expands and cools. That's why physicists claim that at the beginning of the universe when it was hot and dense, the symmetry in nature was the richest. If you know, from this idea also comes the principle of the unification of forces in nature that was supposedly predicted at the beginning of the universe, when symmetry was the richest and the forces were similar in strength. As a matter of fact, there is a counterexample to the claim that the symmetry increases when the temperature increases (this and surrounding ideas are being investigated these days, including by myself). Apparently, behind the asymmetry between matter and antimatter hides a deeper principle or another force that breaks the balance, beyond the standard model, which has not yet received confirmation or an established theoretical source.
I wonder if anyone can explain why symmetry tends to break. Why is there more of one than the other?
The paucity of responses on the site, perhaps indicates financial distress of people who are struggling to make a living and not in matters in the higher part of the pyramid, matters in the soul.
Thanks for the interesting article. Now it turns out that the breaking of symmetry is a "phenomenon" related to food and not just a local case.
Clarifying the issue really seems to be an opening to something new in the field of matter: either to a significant precision/refinement of the standard model (a reasonable alternative) or to a new paradigm in physics if and when more consistent data and findings are accumulated that do not agree with the current one and may be explained by a new theory (less likely, but not impossible within a few decades).
It is possible that this will explain fundamental questions such as the arrow of time, gravity, a new understanding of what is generally perceived today as dark matter, etc., who knows.
