| dc.description.abstract | We present an observation of photon-photon production of τ lepton pairs in ultraperipheral lead-lead collisions. The measurement is based on a data sample with an integrated luminosity of 404 μb−¹ collected by the CMS experiment at a center-of-mass energy per nucleon pair of √sNN = 5.02 TeV. The γγ → τ+τ− process is observed for τ+τ− events with a muon and three charged hadrons in the final state. The measured fiducial cross section is σ(γγ → τ+τ−)= 4.8 ± 0.6 (stat) ± 0.5 (syst) μb, where the second (third) term corresponds to the statistical (systematic) uncertainty in σðγγ → τ+τ−Þ in agreement with leading-order QED predictions. Using σ(γγ → τþτ−), we estimate a model-dependent value of the anomalous magnetic moment of the τ lepton of aτ = 0.001 +0.055 −0.089. | es_ES |
