(2006-10)We discuss several issues related to collinear singularities and the choice of the factorization scale in perturbative QCD calculations. First, we argue in favor of the use of a bottom-quark distribution function, which ...
Direct search for exotic spin zero particles in the di-lepton final state of Higgs-Z associated production in sqrt(s) = 13 TeV pp collisions (2018-12-07)This thesis presents a search for a new exotic spin-0 particle a in 36.47 fb^(-1) of sqrt(s) = 13 TeV pp collisions recorded by the ATLAS detector at the LHC. This analysis is part of a broader search for a H ==> aa ==> ...
