Abstract
Based on a generalized particle diagram of baryons and anti-baryons which, in turn, is based on symmetry principles, this theory predicts the existence of: (a) strange pentaquarks and mesobaryonic particles containing one, two, three and four strange quarks, (b) strange pentaquarks and mesobaryonic particles with zero total strangeness, such as the (̄u ̄u ̄u ̄s̄ s) and (u u u s s̄) particles, (c) a relatively large number of pentaquarks and mesobaryonic particles containing neither strange nor anti-strange quarks (also zero total strangeness) and (d) “bottom-top charmed” pentaquarks and mesobaryonic particles, such as the (t c u b ̄b) particle. The theory, of course, also predicts the anti-pentaquarks and anti-mesobaryonic particles corresponding to all predicted particles. More importantly, this theory predicts the existence of the (u u d c ̄c) pentaquark and the existence of the (u u d c ̄c) mesobaryonic particle. This prediction was confirmed on July 14th, 2015 by CERN researchers with the discovery of two charmonium-pentaquark states with a composition: (u u d c ̄c) with a significance of more than 9 standard deviations. This makes the discovery extremely solid. However, there are doubts on whether the discovered particles are a strongly bound state of five quarks (known as pentaquark) or a weakly bound state of a baryon, (u u d) , and a meson, (c c̄) (mesobaryonic particle or mesobaryonic molecule). Finally, a remarkable aspect of this theory is that it predicts the existence of all the pentaquarks and mesobaryonic particles there exist in nature.
