Containing six quarks instead of the usual three, di-omega could be a new exotic particle, as predicted by a study by the HAL QCD Collaboration, consisting of scientists from the RIKEN Nishina Center for Accelerator-based Science and RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS).
To make the prediction of the existence of this new particle, supercomputing has been used, specifically the so-called Computer K, a supercomputer, produced by the company Fujitsu, located in the RIKEN Advanced Institute for Computational Science in the city of Kobe, Japan.
Dibarion
The new particle would then be a "stranger" dibarion than usual, composed of two "Omega baryons" containing three strange quarks each. If the baryons (mainly protons and neutrons) are composed of three quarks tightly linked, with their charge depending on the "color" of the quarks that compose them, the dibariones would be a system with two baryons.
At the moment, there is a known dibarion in nature: the deuteron, a deuterium nucleus (or heavy hydrogen) that contains a proton and a neutron that are very close together. Di-omega would be the second dibarion found, if its existence were confirmed. According to Shinya Gongyo, of the RIKEN Nishina Center:
We were very lucky to have been able to use the K computer to perform the calculations. This allowed rapid calculations with a large number of variables. However, it took us almost three years to reach our conclusion in the di-Omega.
