Abstract:
Precise measurements of the electromagnetic dipole moments of charged leptons are powerful probes of physics beyond the Standard Model of particle physics. It is essential to study avenues for optimizing the measurement strategies for the anomalous magnetic dipole moment (AMDM) and the electric dipole moment (EDM) of the tau lepton which have recently become accessible at the Large Hadron Collider (LHC). In this talk, I will discuss the findings of a recent pre-print (2410.23070), where we study the prospects of employing optimal observables for measuring the AMDM of the tau lepton in PbPb collisions at the LHC. The performance of optimal observables is investigated in a statistical analysis, assuming an integrated luminosity of 2.0 nb-1. Improvements of sensitivity to the tau AMDM with optimal observables are obtained only for a larger phase space than studied so far, more integrated luminosity, or including the determination of the helicities of the tau leptons. Both, chances and limitations, of optimal observables for the tau AMDM determination will be important to consider in future experiments.
