Using the K computer, scientists predict exotic 'di-Omega' particle. Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, scientists have predicted a new type of 'dibaryon' -- a particle that contains six quarks instead of the usual three. Studying how these elements form could help scientists understand the interactions among elementary particles in extreme environments such as the interiors of neutron stars or the early universe moments after the Big Bang.
