A strange particle has been predicted - the attractive di-Omega

A strange particle has been predicted – the attractive di-Omega

quarky They are the elementary particles that are the basic building blocks of matter (besides leptons). Existing Six types of quarks (and the corresponding six types of antiquarks) – their important advantage is that they do not exist separately, but in particle systems. Thus those made of 3 quarks are called baryons, and those made of 1 quark and 1 antiquark are called mesons.

Physicists have long considered the existence of a so-called alien hadronsIt is made up of more quarks. Experiments conducted since 2003 indicate the presence of ConquerorAnd in 2013, a particle likely composed of four quarks was discovered in Japanese energy accelerator research – ZC (3900). The most wanted are hadrons made of six quarks – the so-called Deparione. Experiments conducted at RIKEN confirm that the existence of such a particle is possible.

There is only one diparion in nature – deuteronThe hydrogen nucleus is made up of a proton and a neutron weakly bonded to each other. Flashes of other Deparion were captured in experiments, but their existence was short-lived.

Although the deuteron is the only known stable debaron, many other particles of this type may exist. RIKEN’s Takuya Sugiura said it’s important to investigate which pairs of baryons make and which don’t, as this provides insight into how quarks form matter.

The theory that describes the interactions of quarks is called Quantum chromodynamics. However, when we want to investigate the potential behaviors of dibarions, things get complicated. The Sugiura team mathematically predicted the presence of the named Diparion Puapnim de Omega.

A large number of variables had to be addressed, so two strong variables were used Supercomputers: K i HOKUSAI.

We were very fortunate to be able to use supercomputers, which greatly reduced the cost and time of computing. It still takes several years to anticipate the attractive presence of D’Omega, Sugiura added.

Despite the complexity of the calculation, di-Omega is alluring The simplest system for studying interactions between baryons. The Fugaku supercomputer is helping physicists in their upcoming simulations.
