Abstract

Scalar diquark model of proton improved by parton intrinsic transverse momentum in hadrons is able to describe the strong scaling violation in proton production large transverse momentum \({{p}_{ \bot }}\) within perturbative QCD in a wide energy range: \(\sqrt s = 11.5\,\,{\text{GeV}}\) at U70 (NRC KI—IHEP, Protvino), \(\sqrt s = 23.4\,\,{\text{GeV}}\) at Tevatron (FNAL, Chicago), and \(\sqrt s = 62\,\,{\text{GeV}}\) at ISR (CERN, Geneva) is presented. Estimates for the production of tetraquark exotic states formed by scalar diquarks in the SPD experiment at the forthcoming NICA collider (JINR, Dubna) have been obtained.
