Welcome to a seminar by Christoffer Petersson

Abstract

In light of the recent Higgs and supersymmetry searches at the LHC, I will discuss how the spectrum and phenomenology of the MSSM Higgs sector is modified in scenarios where supersymmetry is broken spontaneously at around the TeV scale. In such scenarios, additional tree-level contributions to the quartic Higgs potential become relevant and a standard model-like Higgs particle with a mass of 125 GeV can easily be accommodated, without requiring large radiative corrections.

Moreover, the Higgs particle can decay into a gravitino and a neutralino, which subsequently decays promptly into a photon and another gravitino, giving rise to final state consisting of a photon and missing transverse energy. I will estimate the relevant standard model backgrounds and present prospects for discovering this novel Higgs decay channel by the 2012 LHC run.
