Track-finding efficiency at Belle II / Reshma Menon R ; Dr. Seema Bahinipati [BELLE2-MTHESIS-2021-006] Presented on 15 05 2021 MSc

INDIAN INSTITUTE OF TECHNOLOGY BHUBANESWAR / ODISHA,INDIA
Track finding efficiency is a vital input to various sources of systematic uncertainties in analyses involving charged particles.Method to calculate tracking efficiency for hadrons is different than that for muons due their decays and interactions with the material of the detector.Therefore, here we describe a method of estimating the relative tracking efficiency of slow pions in data compared to simulation by focusing on B0→ D∗− π+ decay where the D∗− further decays to D̄0 π− .Owing to its limited phase space,the pion from D∗ decay is traditionally referred as slow-pion due to a small mass difference between the D∗ and D̄0.
