This talk focuses on the likelihood-based combination of the measured cluster energy in the electromagnetic calorimeter with the measured momentum at the track perigee in the Inner Detector for electrons. The primary motivation for performing a combination of the track momentum and cluster energy is to improve electron energy resolution, particularly as it pertains to soft particles that leave...
I present the search of the Higgs boson particle, decaying into two b-quarks produced in association with two top quarks with the ATLAS detector at the LHC. The presentation introduces the motivation for this challenging physics search and the description of the phenomenology of this final state. I present previous ATLAS results related to my analysis, jet trigger studies I performed and...
The top quark, first observed by the CDF and D0 Col-
laborations in 1995 [1, 2], is the heaviest of all elementary
particles. Due to the large top-quark mass, the measure-
ment of the production and decay properties of top quark
pairs in proton-antiproton collisions provides an im-
portant test of the standard model of particle physics
(SM) that may unveil the presence of new...
