Description

Particle Identification (PID) is crucial for all analysis at LHCb. The PID machinery at this experiment includes both hardware and software resources to distinguish between electrons, kaons, pions, muons and protons. A key part in particle identification is the estimation of the efficiencies of PID selection criteria through data-driven methods. For that, the tool PIDCalib (Particle IDentification Calibration) was created. Despite its proved usefulness, this tool also comes with its flaws. In this talk, I will address the fact that PIDCalib can not account for decays-in-flight (DIF) of pions and kaons to muons, which is a huge source of muon misidentification (misID). Moreover, I will present the plans for a tool that can evaluate and correct the muon misID.
