摘要

由强子中的部分子本征横动量改进的质子标量双夸克模型能够描述质子产生过程中的强尺度违逆：在宽能量范围内，微扰QCD中的大横动量\({{p}_{ \bot }}\)：在U70 (NRC KI-IHEP, Protvino) \(\sqrt s = 11.5\,\,{\text{GeV}}\)，在Tevatron （FNAL，芝加哥）\(\sqrt s = 23.4\,\,{\text{GeV}}\)，在ISR （CERN，日内瓦）\(\sqrt s = 62\,\,{\text{GeV}}\)。在即将到来的NICA对撞机（JINR, Dubna）上，已经获得了由标量双夸克在SPD实验中形成的四夸克奇异态的估计。

Diquarks for Large-p⊥-Baryon Production at High-Energy p–p Collisions

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.
