  1. 60. Type II lepton number violation at the LHC
    Jonathan Kriewald (Jožef Stefan Institute)

    Parallel Session Talk

    We examine the prospect of observing genuine lepton number violating (LNV) signals at hadron colliders in the context of the Type II seesaw mechanism. The model features smoking gun signals involving same-sign di-leptons and jets that may be the primary observable channel in certain regions of the parameter space. The flavour composition of final-state charged leptons in the minimal model is...

  3. 88. Higgs decays into lepton pairs and a photon

    We present a study of Higgs boson decays involving a photon and leptonic or neutrino pairs within the Standard Model. For $H \to \ell^+ \ell^- \gamma$ with $\ell = e, \mu$, we calculate differential decay rates, branching fractions, and forward-backward asymmetries, providing analytic expressions for experimental analyses. Our approach distinguishes the resonant $H \to Z\gamma$ contribution...

  4. 72. Background processes in Higgs decay to Z gamma
    Aliaksei Kachanovich (ULB)

    Parallel track
    Parallel Session Talk

    In measurements by the ATLAS and CMS Collaborations, the number of events for Higgs decay into a Z boson and photon is 2.2 $\pm$ 0.7 times higher than predicted by the Standard Model. For the $H \to Z \gamma$ process, this decay is reconstructed from $H \to \ell \ell \gamma$, where $\ell = e, \, \mu$. In our work, we aim to resolve this anomaly by exploring potential additional background...
