I am Zareen Tahsin Anjum, graduated in Nuclear Engineering from University of Dhaka, Bangladesh. 
I am currently working as summer student on the ATLAS experiment at CERN, 
focusing on trigger performance studies in the 1 lepton + 3 tau (1l3τ) channel of Di-Higgs 
production. As part of my project, I implemented ROOT-based tools to evaluate tau trigger 
efficiencies across multiple signal configurations. My work aims to optimize trigger selections for 
improved sensitivity to rare processes like di-Higgs Boson events, contributing to broader efforts in precision measurements.
