Title: The Lightest Higgs Boson Mass in the MSSM with Strongly Coupled Spectators
Date (JST): Fri, Mar 01, 2013, 13:30 - 14:30
Place: Seminar Room A
Abstract: We propose a new mechanism for producing a Higgs boson mass near 125 GeV within the MSSM. By coupling the MSSM Higgs boson to a set of strongly interacting elds, large corrections to the Higgs quartic coupling are induced. Although the Higgs doublets do not participate in the strong dynamics, they feel the e ects of the strongly coupled sector via (semi-)perturbative interactions. These same strong dynamics are also capable of generating the -term. Additionally, this strong sector is in the conformal window, which drives the couplings to an infrared xed point and naturally generates model parameters of the appropriate size.
