We use the following: the physical properties of the magnetic field are related to the Kolmogorov scale, which made it possible to estimate the α-effect of the space curvature parameter at each moment of time. On the other hand, in an expanding hyperbolic space, a change in the density of magnetic helicity is observed, unrelated to the α-effect. We compare the two indicated factors of change in magnetic helicity and conclude that, at a fairly stable stage of expansion, the α-effect caused by the influence of scalar curvature on the Kolmogorov MHD spectrum becomes small.</p>","PeriodicalId":729,"journal":{"name":"Physics of Particles and Nuclei","volume":"56 2","pages":"269 - 274"},"PeriodicalIF":0.6,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100402","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}

Calculations of cross sections of DM particle production are presented for the process of associated DM production with a gauge <i>Z</i><sup>0</sup> boson in a model with a two-doublet Higgs sector containing an additional scalar or pseudoscalar. It is shown that when analyzing the data of proton–proton collisions at an energy in the center-of-mass system of 13 TeV with a corresponding integrated luminosity of 137 fb<sup>−1</sup>, collected by CMS experiment at the LHC in 2016–2018, no significant excess of the expected signal over the background predicted by the standard model is observed. Constraints on the parameter space of (2HDM+a) scalar portal model obtained by CMS during the LHC second run (Run 2) and prospects for the third run are discussed.</p>","PeriodicalId":729,"journal":{"name":"Physics of Particles and Nuclei","volume":"56 2","pages":"340 - 345"},"PeriodicalIF":0.6,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100175","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}
