In proton–proton interactions studies of hadron jets devote to the better understanding of some basic features of strong interaction and search for the physics beyond of Standard Model. First results have been obtained for massive gauge bosons and antitop-top pair production in proton–nuclear and heavy ion collisions at multi-TeV energies. The collectivity has been observed for various particle and beam species, in particular, in collision of small systems. Experimental results obtained for discrete symmetries of strong interaction at finite temperature confirm indirectly the topologically non-trivial structure of the vacuum. The recent measurements of femtoscopic correlations provide, in particular, the indirect estimations for parameters of hyperon-nucleon potentials which are essential for study of inner structure of compact astrophysical objects. Novel mechanism for multiparticle production due to collectivity can be expected in very high energy nuclear collisions and it may be helpful for better understanding of the nature of the muon puzzle in ultra-high energy cosmic ray measurements. Thus studies of collective effects in strong interaction processes provide new important results for relativistic astrophysics, cosmology and cosmic ray physics, i.e. have interdisciplinary significance.</p>","PeriodicalId":729,"journal":{"name":"Physics of Particles and Nuclei","volume":"56 5","pages":"1125 - 1133"},"PeriodicalIF":0.5,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, we establish that the Coulomb potential of the so-called trapping charges is a Morse function and give an explicit formula for its hessian at the trapped point. These facts combined with the recent results of Y.-L. Tsai on three point charges with equal magnitudes, enable us to establish that the Coulomb potential of sufficiently small identical uniformly charged discs centered at the vertices of regular triangle has exactly seven critical points. This implies that, for triangular shapes sufficiently close to the regular triangle, the number of equilibrium points of appropriately charged small discs centered at the vertices is not less than seven.</p>","PeriodicalId":729,"journal":{"name":"Physics of Particles and Nuclei","volume":"56 4","pages":"1022 - 1024"},"PeriodicalIF":0.5,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144918473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
