Description |
The ATLAS and CMS collaborations have put forward an extensive program
of searches for new physics, aiming to cover new physics theories as
widely as possible. The results of this searches are typically
interpreted in the context of popular models or simplified model
topologies. However, there exist a plethora of beyond vanilla BSM
theories and scenarios that are not directly covered by the
experimental analyses. This has lead to the emergence of a joint
effort between experimenters and theorists to build a framework for
the reinterpretation of LHC results. The first part of this talk will
serve as an introduction to this very active framework.
On the second part, by means of LHC reinterpretation, we explore the
collider phenomenology of an interesting beyond vanilla theory: The
Minimal Dirac Gaugino Supersymmetric Standard Model (MDGSSM). By
introducing Dirac gauginos (instead of Majorana), we obtain an
enriched phenomenology and distinctive LHC results are expected.
Concretely, the electroweakino sector of the MDGSSM is characterised
by an enriched spectra of neutralinos and charginos exhibiting
naturally small mass splittings and thus, yielding a frequent presence
of scenarios with Long Lived Particles (LLPs). Moreover, in the
coloured sector, production cross sections are enhanced for gluinos,
while for squarks, they are suppressed. Here, we shall derive current
LHC limits on the aforementioned sectors of the MDGSSM, while also
including bounds from dark matter observations.
