BARYONS IN A HYBRID QUARK-DIQUARK MODEL

Giuseppe Galatà

Open full text 1 citations

Abstract

One of the main problems in baryon spectroscopy is the presence of many so-called "missing resonances". A possible solution to this problem is to describe two correlated quarks inside the baryons by means of the diquark effective degree of freedom. Three different quark-diquark model are developed and compared. Some theoretical predictions are given and compared with the available experimental data.
