Probing electromagnetic moments of the tau lepton in PbPb collisions at the FCC-hh
Abstract
A production of a pair of tau leptons in PbPb collisions at the FCC-hh collider is examined. The 95\% C.L. exclusion limits, as well as 3$σ$ and 5$σ$ sensitivity limits on the anomaly magnetic moment of the tau lepton $a_τ$ and its electric dipole moment $d_τ$ are obtained. A comparison with bounds on $a_τ$ and $d_τ$ for other future colliders are given.
