TAU Identification Improvements for ATLAS Phase-1 Upgrades in L1Calo Trigger System

ATLAS is one of the biggest detectors at the Large Hadron Collider (LHC) at CERN. It is designed to study high-energy particle collisions. Within the detector, there are two levels in the trigger system, Level 1 and High Level Trigger (HLT). The main objective of this project is to study the tau candidate particles in L1Calo to improve the tau identification in the L1Calo trigger system for the phase-1 upgrades in ATLAS. This is done by exploring the matching efficiency algorithm and studying the rCore energy.
