The observation is based on a data set recorded with the CMS detector at the LHC at a center-of-mass energy of $13~\\mathrm{TeV}$ and corresponding to an integrated luminosity of $138~\\mathrm{fb}^{-1}$.  Events with a small number of tracks close to the di-$\\tau$ vertex are selected to isolate photon-induced processes. Limits on the anomalous electromagnetic moments of the $\\tau$ lepton originating from potential new physics effects on the $\\gamma\\tau\\tau$ vertex are also set.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.152621.v1/t1","@type":"Dataset","description":"Normalized distributions of $N_\\mathrm{tracks}^\\mathrm{PU}$ in windows of 0.1 cm width along the $z$ axis using a sample of $\\mu\\mu$ events...","name":"Figure 3: Number of pileup tracks"},{"@id":"https://doi.org/10.17182/hepdata.152621.v1/t2","@type":"Dataset","description":"Normalized distributions of of the number of reconstructed tracks ($N_\\mathrm{tracks}$) in a 0.1 cm wide window in the $z$ direction,...","name":"Figure 4: Number of HS tracks"},{"@id":"https://doi.org/10.17182/hepdata.152621.v1/t3","@type":"Dataset","description":"Distributions of $m_{\\mu\\mu}$ in the $\\mu\\mu$ channel of the $N_\\mathrm{tracks}=0$ and 1 categories with acoplanarity $A<0.015$, and for the combined...","name":"Figure 5: Rescaling of elasic-elastic contribution"},{"@id":"https://doi.org/10.17182/hepdata.152621.v1/t4","@type":"Dataset","description":"Multiplicative $N_\\mathrm{tracks}$-dependent corrections to the $\\tau_\\mathrm{h}$ MFs, in the $\\mathrm{e}\\tau_\\mathrm{h}$ final state in the high-$m_\\mathrm{T}$ CR, for the $h^{\\pm} +...","name":"Figure 7a: Corrections to jet mis-ID"},{"@id":"https://doi.org/10.17182/hepdata.152621.v1/t5","@type":"Dataset","description":"Multiplicative $N_\\mathrm{tracks}$-dependent corrections to the $\\tau_\\mathrm{h}$ MFs, in the $\\mathrm{e}\\tau_\\mathrm{h}$ final state in the SS CR, for the $h^{\\pm} +...","name":"Figure 7b: Corrections to the $\\tau_\\mathrm{h}$ MFs"},{"@id":"https://doi.org/10.17182/hepdata.152621.v1/t6","@type":"Dataset","description":"Observed and predicted $m_\\mathrm{vis}$ distributions in the $\\mathrm{e}\\mu$ final state for events with $N_\\mathrm{tracks} = 0$.
