Multiphoton signatures of supersymmetry at the LHC

Presented by Christoffer PETERSSON on 21 Jul 2014 from 15:30 to 15:50
Type: SUSY Phenomenology
Track: SUSY Phenomenology


I will discuss how the usual phenomenology of gauge mediated supersymmetry breaking can be significantly modified by the non-minimal assumption that supersymmetry is broken in more than one hidden sector. Such multiple hidden sector models give rise to light neutral fermions called pseudo-goldstini and due to the extra decay steps they provide, where soft photons are emitted, these models give rise to multiphoton plus missing energy signatures. Due to the softness of the final state spectrum, the existing LHC searches turn out to be very poorly sensitive. However, by making use of the multiplicity of final state particles, it would be possible to probe these models and I will propose some new dedicated LHC searches.
