R-parity violating supersymmetry and neutrino physics: experimental signatures

TL;DR

This paper reviews R-parity violating supersymmetry models that generate neutrino masses, focusing on their LHC signatures, especially displaced objects, and discusses their implications for dark matter.

Contribution

It provides a comprehensive review of RPV SUSY models with neutrino mass generation, emphasizing experimental signatures and recent LHC results.

Findings

LHC experiments have observed signatures consistent with displaced objects in RPV SUSY models.

RPV SUSY models can naturally explain neutrino masses and accommodate a 125-GeV Higgs boson.

Implications for dark matter are discussed within the context of these models.

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 paper, we discuss RPV scenarios where neutrino masses are naturally generated, namely RPV through bilinear terms (bRPV) and the $\mu$-from-$\nu$ supersymmetric standard model ($\mu\nu$SSM). 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.
