The effects of jet quenching, arising from the interaction of jets with the quark–gluon plasma, are quantified by comparing trigger-normalized recoil yields in central and peripheral collisions. Suppression of the recoil yield in central collisions is observed, indicating medium-induced partonic energy loss due to quenching. The ratio of recoil jet yields for small and large resolution parameter is found to be suppressed in central relative to peripheral collisions, characteristic of medium-induced intra-jet broadening. The results are compared to similar measurements in smaller and larger collision systems, providing unique insight into the system-size dependence of jet quenching.","PeriodicalId":20162,"journal":{"name":"Physics Letters B","volume":"67 2 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149085010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Gohain, Kalyan Bhuyan","doi":"10.1016/j.physletb.2026.140993","DOIUrl":"https://doi.org/10.1016/j.physletb.2026.140993","url":null,"abstract":"The origin of the observed baryon imbalance of Universe remains an unresolved problem in modern cosmology. In this work, we investigate whether baryon asymmetry can be realized in the presence of power-law corrections to horizon entropy motivated by quantum entanglement. Within the emergent-spacetime framework, we derive the modified Friedmann and Raychaudhuri equations and implement a perturbative expansion around the radiation-dominated background. We demonstrate that the entropy correction results in a nonzero curvature scalar (<ce:italic>R</ce:italic>) and its time derivative, thereby enabling the generation of baryon asymmetry in a regime where the standard scenario yields no asymmetry. We calculate the baryon number to entropy ratio arising from the curvature-current interaction and constrain the model parameters using observational bounds. The measured baryon excess is reproduced for the value (<ce:italic>α</ce:italic> ≃ 1.974) of the entropy correction quantity, demonstrating that entropic modifications to cosmological dynamics provide a viable and geometrically motivated mechanism for baryogenesis. This result highlights that even minute entanglement-induced corrections can leave observable imprints on early-universe dynamics.","PeriodicalId":20162,"journal":{"name":"Physics Letters B","volume":"1 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149085013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The cavities are isothermal boxes that can make the (charged) McVittie black hole thermodynamically stable. The (charged) McVittie black hole is a dynamical black hole, so the traditional action method can hardly be used to calculate the cavity temperature. As dynamical spacetimes with spherical symmetry, they do not have Killing vectors but have Kodama vectors <ce:italic>K<ce:sup loc=\"post\">a</ce:sup></ce:italic>, which are found to be precisely (∂/∂<ce:italic>t</ce:italic>)<ce:sup loc=\"post\"><ce:italic>a</ce:italic></ce:sup>, a result that is quite remarkable. We can also obtain their Hawking temperature at the apparent horizons. Based on the Kodama vector and Hawking temperature, we find that the Tolman relation can be used to calculate the cavity temperature if one replaces the Killing vector in the Tolman relation by the Kodama vector for dynamical spacetimes with spherical symmetry. Furthermore, since (charged) de Sitter black hole can be viewed as a special case of the (charged) McVittie black hole, we also obtain the cavity temperature by setting <ce:italic>H</ce:italic><ce:sup loc=\"post\">2</ce:sup> to be Λ/3, and the results are exactly the same as those from the traditional action method, while our method seems much easier.","PeriodicalId":20162,"journal":{"name":"Physics Letters B","volume":"10 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
