The strange behavior of mesons indicates the presence of strange particles and forces that do not conform to the Standard Model of Physics.
Monad’s behavior is strange. This start can be applied to almost any subatomic particle. Everything at the subatomic level is weird, weird, weird. But the standard model of physics can adapt to it. However, the muon has just turned the model upside down as the physicist’s bible, or, from a more positive perspective, it has just opened more doors to the unknown subatomic particle universe.
These days, the rising particles are muons. A new experiment confirms its strange behavior, and we can only explain it when there are “virtual”, short-lived, very short-lived particles that appear and disappear almost simultaneously, and when they appear, they will affect the muons. This strange behavior. Said they “push” and it is the reason for their strange behavior. Therefore, new unknown forces may be dominating the subatomic world.
These particles will also appear from the moment matter and antimatter come together and everything collapses (we warn that this will simplify a lot).
This means that on the scale where ants are giants, physicists may not be aware of many other weird particles and forces. Even without CERN, the underground colossus is dedicated to exploding atoms in search of the most subtle things, because even CERN does not smell them.
Today, observers of subatomic particles are like Galileo asking the world to approach his telescope. Galileo discovered a lens for observing the universe, which he could not understand at the time. Nowadays, lenses aimed at the minimum are advanced technical means, and news that the small world is more Martian than Mars is beginning to spread.
Where’s that meson?
A meson is an elementary particle, which means it will not break down into other particles. It is found in cosmic rays, and they pass through us permanently without notifying us (cosmic radiation). Its existence time is very short (2.2 microseconds). In other words, there is nothing, or almost nothing.
The mass of a meson is very small, but it is almost 200 times that of an electron: 0.106 GeV.
Experts say that the strange behavior of mesons indicates the existence of strange particles and external forces that surpass the standard model of physics.
They have had signs of this anomaly before, but a new set of measurements increases the likelihood of this anomaly. Let’s take a look at the rarity of mesons:
Mesons are charged particles, so when placed in a magnetic field, they start to spin. Physicists can measure the frequency of the spin caused by the phenomenon of spin, in which the spin axis of the particle oscillates slightly, allowing them to make so-called wobble diagrams.
The strange dance of the meson
The frequency at which a meson rotates and how it dances in a magnetic field depends on its interaction with other particles and forces, and is represented by a number called the g-factor.
Using the standard model of particle physics, researchers can predict very precisely what this number should be. However, this number is inconsistent with what they have observed.
In 2006, the experimental results of Brookhaven National Laboratory in New York began to differ from those theoretical predictions: the muon’s rotation speed was faster than expected.
The statistical significance of the results is not sufficient to indicate that the standard model is incorrect, so the experiment must be repeated.
Fermilab confirms rarity
now at Fermilab Illinois confirmed the concern that past results have caused. William Morse of Brookhaven National Laboratory said: “We may have made a mistake at Brookhaven, but then Fermilab had a more complicated setup and could get a different answer, but they didn’t. .”
This anomaly may be caused by a quantum mechanical phenomenon called virtual particles. These are pairs of quantum and its antimatter, which are produced due to quantum fluctuations and then disappear. Although they are short-lived, they may affect the behavior of real particles such as muons.
“Not only are known particles appearing and disappearing, but there are also particles that have not yet been discovered”
Because these virtual pairs are random and come from time and space itself, they can be any type of particle. Some may be what we already know, such as electrons and their antimatter companion positrons, but some may be stranger. One of the Fermilab team members, Joe Price of the University of Liverpool, said: “Not only are known particles appearing and disappearing, but they have not yet been discovered.”
However, the model we use to predict the g factor of muons only includes the expected effects of known virtual particles. Therefore, if our experiment conflicts with those models, it indicates the possibility of other particles besides muons. Control those models.
Fermilab’s results came after a physicist at the Large Hadron Collider at the CERN Particle Physics Laboratory in Geneva, Switzerland announced the discovery of how muons decompose. Price said the two may be related. “Maybe it’s the same physics from a different perspective, or maybe it’s a different physics.”
Like CERN measurements, there is not enough data to show that there must be new particles and forces beyond the standard model. However, researchers at Fermilab have only evaluated one-tenth of the experimental data so far, and are continuing to collect more data, which is why Price said they should be able to quickly tell whether this anomaly is Is it really caused by foreign particles or is it just an anomaly? The product of statistical uncertainty. These additional measurements can also help us narrow down the range of strange particles that may exist.
