U(1)-extensions of the MSSM in light of the Higgs discovery

Presented by Mr. Agamemnon SFONDILIS on 25 Jul 2014 from 14:30 to 14:50
Type: SUSY Phenomenology
Track: SUSY Phenomenology


Motivated by the discovery of a Higgs particle, with a relatively large mass and many production and decay modes under study, I consider a phenomenological U(1)-extension of the MSSM. Such extensions, while maintaining all the benefits of the MSSM such as unification, give extra contributions to the Higgs mass, as well as extra D-term contributions to the stop masses, which can improve naturalness. They can also serve as benchmarks for experiments in searching for SUSY beyond the MSSM. I describe a bottom-up approach allowing for generic charge assignments, where one has more complementarity between the various experimental constraints compared to top-down models such as the E6SSM. For example, decay modes of the Z' that are neglected in the standard searches can become important. I will combine and contrast constraints from visible and invisible Higgs branching fractions, precision tests, and Z' searches. I will show allowed regions in parameter space and discuss prospects with the upcoming run 2 of the LHC.
