Vacuum tadpole contributions in top quark production

Verfügbares Masterarbeitsprojekt

Supervisors: Andre Hoang and Massimiliano Procura

Abstract: Radiative tadpole corrections to the Higgs field vacuum expectation value of the Standard Model  coming from the interaction between the Higgs boson and the top quark are very large and affect the relation of the top quark mass determined from experiments and the top quark Yukawa coupling to the Higgs boson. In the project these large tadpole corrections are implemented in a jet mass cross section that is used for top quark mass measurements using different renormalization schemes for the vacuum expectation value. It shall be then investigated in which way these scheme choices can affect studies of the vacuum stability of the Standard Model. The results are relevant for the interpretation of the top quark mass measurements at the Large-Hadron-Collider.
