Physics Theory Seminar with Juhi Dutta

Juhi Dutta (hosted by Bhupal Dev) from the University of Oklahoma will be presenting a seminar on "Prospects of natural anomaly mediated SUSY breaking at HL-LHC"

The minimal anomaly mediated supersymmetry breaking (AMSB)  models are currently in conflict with constraints from naturalness, Higgs mass and particle mass limits from LHC as well as  from dark matter searches on the WINO-like neutralino which serves as the lightest SUSY particle (LSP). These conflicts may be avoided by introducing minor changes to the underlying phenomenological models consisting of non-universal bulk scalar Higgs masses and A-terms, providing a setting for  natural anomaly-mediation (nAMSB).  In nAMSB, the WINO is still expected to be the lightest of the gauginos, but the higgsinos are expected to be the lightest electroweakinos (EWinos) in accord with naturalness.

Dutta and her team have examined what sort of spectra are expected to emerge when nAMSB arises from a string landscape setting and explore the LHC phenomenology of nAMSB models via higgsino pair production and wino pair production. We characterize and present results for the dominant LHC signatures arising from the remaining patch of parameter space which is fully testable at high-luminosity LHC via EWINO pair production searches.

This lecture was made possible by the William C. Ferguson fund.
