Z'-induced Invisible Right-handed Sneutrino Decays at the LHC

TL;DR

This paper investigates the potential for detecting invisible right-handed sneutrino decays originating from a Z' boson at the LHC, which could help distinguish B-L extended supersymmetric models from other SUSY scenarios.

Contribution

It provides a detailed analysis of the LHC's sensitivity to invisible sneutrino decay signals from Z' bosons within B-L extended MSSM, including simulation of various detection channels.

Findings

Substantial sensitivity to sneutrino decay signals at Run 2 luminosities.

Effective discrimination of B-L extended MSSM from other SUSY models.

Potential for using mono-jet, photon, and Z-radiation channels for detection.

Abstract

The invisible signals of right-handed sneutrino decays originating from a Z' are analysed at the Large Hadron Collider. The possibility of accessing these events helps disentangling the B-L extension of Minimal Supersymmetric Standard Model from more popular scenarios of Supersymmetry. We assess the scope of the CERN machine in establishing the aforementioned signatures when accompanied by mono-jet, single-photon or Z-radiation probes through sophisticated signal-to-background simulations carried out in presence of parton shower, hadronisation as well as detector effects. We find substantial sensitivity to all such signals for standard luminosities at Run 2.
