"Precision Measurement of the Top Quark Mass"

Abstract: The top quark, discovered in 1995, is the heaviest quark in the Standard Model. The precise measurement mass of the top quark is an excellent probe for testing the Standard Model and the physics beyond the Standard Model. The top quark pair production provides the current measurement of the top quark mass with data from the LHC experiment. The current measurement is performed on the top pair decaying into leptons and a shower of quarks and gluons, called a jet. In this talk, I will present a novel analysis for measuring the top quark mass. This novel analysis selects top quarks which decay into a W-boson and a b-quark. The final event signature will consist of a lepton from the W-boson decay and a J/psi meson from the b-quark hadronization. I will present some preliminary results for the analysis and provide the challenges and the advantages for this analysis.
