Physicists propose new particle explanation for mysterious LHC signals
Researchers have devised a theoretical framework that could explain puzzling excess signals detected at CERN's Large Hadron Collider around 95 GeV—hints of previously unknown particles that multiple experiments have observed. The findings could reshape our understanding of fundamental physics and validate alternative models to the standard theory of particle interactions.
Originaltitel: Superposition of CP-even and CP-odd Higgs resonances: Explaining the 95 GeV excesses within a two-Higgs-doublet model
<p>We propose an explanation for the observed excesses around 95 GeV in the diphoton and ditau invariant mass distributions, as reported by the CMS collaboration at the Large Hadron Collider. These findings are complemented by a long-standing discrepancy in the bb<overline> invariant mass at the Large Electron-Positron Collider. Additionally, the ATLAS collaboration has reported a corroborative excess in the diphoton final state within the same mass range, albeit with slightly lower significance. Our approach involves the superposition of CP- even and CP- odd Higgs bosons within the type-III two-Higgs doublet model to simultaneously explain these excesses at 1 sigma confidence level, while remaining consistent with current theoretical and experimental constraints.</p>
