Search For Higgs Pair Production In The Bbτ Τ Final State With The Atlas Detector At The Large Hadron Collider, Puja Saha
Graduate Research Theses & Dissertations
Abstract: This is a search for a Beyond Standard Model (BSM) heavy scalar in the ATLAS detector at 13 TeV center of mass energy using Run 2 data set recorded in 2018 with an integrated luminosity 58.5 fb^{-1}. The heavy scalar (X) decays to two Standard Model (SM) like light Higgs (H) bosons that decay into the bbtautau final state. Particularly, the semi-leptonic final state of two tau's is considered in this search where one tau decays in leptonic final state and other to a hadronic final state. No evidence of a new scalar found, so upper limits are set …
