Exploring neutrino physics at LHC via R-parity violating SUSY

TL;DR

This paper reviews R-parity violating supersymmetric models that naturally generate neutrino masses, discusses their LHC phenomenology with displaced objects, and explores implications for dark matter, highlighting recent experimental results.

Contribution

It provides a comprehensive review of RPV SUSY models with neutrino mass generation and their distinctive collider signatures at the LHC.

Findings

LHC experiments have observed signatures consistent with displaced objects predicted by RPV SUSY.

RPV models with bilinear terms and 'mu from nu' scenario can accommodate a 125-GeV Higgs boson.

Implications for dark matter in RPV SUSY models are discussed.

Abstract

R-parity violating supersymmetric models (RPV SUSY) are becoming increasingly more appealing than its R-parity conserving counterpart in view of the hitherto non-observation of SUSY signals at the LHC. In this talk, RPV scenarios where neutrino masses are naturally generated are discussed, namely RPV through bilinear terms (bRPV) and the "mu from nu" supersymmetric standard model. The latter is characterised by a rich Higgs sector that easily accommodates a 125-GeV Higgs boson. The phenomenology of such models at the LHC is reviewed, giving emphasis on final states with displaced objects, and relevant results obtained by LHC experiments are presented. The implications for dark matter for these theoretical proposals is also addressed.
