It is shown that in the energy range of the NICA collider, fractions of neighboring quarks can participate in the interaction of nuclei.

It appears that the hadronization of quark systems in a jet is determined by the dynamics of interaction with the QCD vacuum, providing hope for studying the properties of this vacuum.</p>","PeriodicalId":729,"journal":{"name":"Physics of Particles and Nuclei","volume":"57 5","pages":"963 - 967"},"PeriodicalIF":0.5,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1063779626701169.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
