A first order formulation of gravity is presented to include gravity in Quantum Mechanical Lagrangian of fermions. It is seen that fermions minimally coupled to gravity gives rise to a torsionless effective theory with a quartic interaction. After passing through a thermal background the most generic form of contortion contributes to neutrino effective mass. This effective mass can change the current oscillation parameters.","PeriodicalId":36085,"journal":{"name":"Letters in High Energy Physics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47610356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on a scenario in which the first-order EWPT is driven by a light scalar s with a mass between 15 and 60GeV. A search for exotic decays of the Higgs boson into a pair of spin-zero particles, h → ss , where the s -boson decays into b -quarks promptly is presented. The search is performed in events where the Higgs is produced in association with a Z boson, giving rise to a signature of two charged leptons (electrons or muons) and multiple jets from b -quark decays. The analysis is considering a scenario of analyzing 5000fb − 1 e + e − collision data at √ s = 240GeV from the Circular Electron Positron Collider (CEPC). This study with 4 b final state conclusively tests the expected sensitivity of probing the light scalars in the CEPC experiment. Upper limits are set on the Higgs to double singlet cross-section times branching ration with 95% CL. The ratio of these limits over the SM production cross-section is estimated to be around 5 × 10 − 4 for the mass range of 15–60GeV. The sensitivity reach is significantly higher than that can be achieved at the LHC.","PeriodicalId":36085,"journal":{"name":"Letters in High Energy Physics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135612334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
