Abstract
The quest for lepton-flavour-violating processes at the LHC represents one of the key searches for new physics beyond the Standard Model. This review summarizes the direct searches for lepton-flavour-violating decays of heavy bosons with the ATLAS detector, using proton-proton collisions at the centre-of-mass energy of 13 TeV.
Highlights
The search for processes beyond the Standard Model (SM) is one of the goals of the physics programme at the Large Hadron Collider (LHC) at CERN
LFV decays of the Z boson are predicted by models with heavy neutrinos [1], extended gauge models [2] and supersymmetry (SUSY) [3], which allows for LFV decays of the Higgs boson [4, 5]
This paper summarizes the searches for LFV decays performed with the ATLAS detector using pp collision data collected at the center-of-mass energy of 13 TeV
Summary
The search for processes beyond the Standard Model (SM) is one of the goals of the physics programme at the Large Hadron Collider (LHC) at CERN. In particular Minimal Supersymmetric SM scenarios with very high energy scale of the SUSY particle masses mSUSY present a non-decoupling behavior of the Higgs boson partial widths in two leptons of different flavor, with respect to mSUSY. This feature opens the possibility of detecting indirectly scenarios with very high mSUSY via LFV Higgs boson decays. The latest ATLAS results on LFV decays of Z, Higgs bosons and searches for other bosons decaying via LFV processes are summarized in sections 3, 4, and 5, respectively
