Description
rocesses involving tau leptons are important for Standard Model measurements and searches for new physics at the LHC. Due to the challenges of modelling hadronic tau decays and their associated backgrounds, data-driven estimation techniques are strongly favoured. This talk presents the Universal Fake Factor method, a novel approach for estimating the contribution of jets misidentified as tau leptons in ATLAS experiment data analysis. This method uses a linear combination of transfer factors, called Fake Factors, derived from samples enriched in different jet sources (light quarks, gluons, b-quarks, and pile-up) to predict the Fake Factor for any Signal Region. The systematic uncertainty on the estimated Fake Factors is evaluated and found to be between 15% and 35%, depending on the tau lepton transverse momentum and the tau associated charged-particle multiplicity. Given the method's generality, other experiments can also adopt it to estimate this type of background.
