---------------------------------------------------------------------------------------------- Project: B20 Title: Exploring muon vs. pion Identification at Belle II using Machine Learning and CsI(Tl) Pulse Shape Discrimination DESY group: Belle II Type: Online project Duration: 19 Jul - 10 Sep 2021 Description: The Belle II experiment located at the SuperKEKB electron-positron collider in Japan is the first high energy collider experiment to implement CsI(Tl) pulse shape discrimination as a new method for calorimeter-based particle identification. This technique uses the particle-dependent scintillation emission of the CsI(Tl) crystals in the electromagnetic calorimeter to identify particles which interact via the strong nuclear force. Using data collected by Belle II, this project combines machine learning with the new calorimeter information provided by CsI(Tl) pulse shape discrimination to explore the potential for separating ionizing pions and muons. The successful realization of this novel approach to ionizing pion vs. muon identification would have far reaching impact in numerous Belle II analyses. Special Qualifications expected: Prior experience with python scripting and machine learning will be beneficial as well as experience working in a linux computing environment.
