“…Baryon resonances problems have already been treated with other quark-diquark models, [2][3][4] unquenching quark models, [5][6][7][8][9][10] and hypercentral models [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] but in the end baryon resonances still remain an open problem. 31…”

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.
