A particle observed in the Paramilab laboratories behaves differently than expected; The length of its life and how it decomposes into other particles are not understood

The observed particle is a meson - a particle consisting of a quark and an anti-quark, which the strong nuclear force binds between them. The quarks in this case are a "strange" quark, which is relatively light, and a "charm" antiquark, which is a heavy particle. It is the heaviest food observed so far among the foods consisting of a light particle and a heavy particle. Such substances are relatively easy to treat mathematically, since in the relative motion between the two particles it can be assumed that the heavy particle is at rest and only the light particle moves relative to it.
food and life
The life time of such food, at the end of which it breaks down into lighter foods, is expected to be short - so short that it is difficult to distinguish it. But in practice this food lasts longer than its lighter relatives. This is surprising, because assuming that all other parameters do not change, it is the mass of the food that determines its lifespan, and the heavier it is, the shorter its lifespan.
In said food, it is the "other parameters" that make it interesting. In addition to its life time, which is three times longer than that of lighter foods, the way it decays is also puzzling: when a particle decays, there are several possible paths, each with a characteristic probability. The decomposition of such food can yield one of two light foods: ata or kaon food.
Aspects of nuclear power
Any such decomposition produces, in addition to the light food, some additional particles that are not relevant to our case. The probability for each of the events can be calculated. In practice, it turns out, an excess of eta particles is observed; This breakdown is 6 times more common than expected. This seems to indicate new and interesting aspects of how the strong nuclear force works in food.
The research group (Segmented Large X baryon Spectrometer), which includes research institutes from around the world (including Tel Aviv University) used data from an experiment carried out at the Tevatron accelerator and investigated collisions between accelerated protons and stationary diamond and copper targets. The experiment was actually stopped in 1997, but the data analysis carried out now reveals the new particle for its strange behavior.
