LHC signals for neutrino mass model in bilinear R-parity violating mAMSB

TL;DR

This paper explores how a specific neutrino mass model with bilinear R-parity violation in supersymmetry can be tested at the LHC, focusing on displaced vertices from long-lived particles.

Contribution

It analyzes the LHC phenomenology of a neutrino mass model with bilinear R-parity violation, highlighting the potential of displaced vertex searches to probe the model's parameter space.

Findings

Displaced vertices provide the best detection channel.

Almost all parameter space can be tested with 10 fb-1.

LHC has greater reach than Tevatron for this model.

Abstract

We investigate a neutrino mass model in which the neutrino data is accounted for by bilinear R-parity violating supersymmetry with anomaly mediated supersymmetry breaking. We focus on the CERN Large Hadron Collider (LHC) phenomenology, studying the reach of generic supersymmetry search channels with leptons, missing energy and jets. A special feature of this model is the existence of long lived neutralinos and charginos which decay inside the detector leading to detached vertices. We demonstrate that the largest reach is obtained in the displaced vertices channel and that practically all of the reasonable parameter space will be covered with an integrated luminosity of 10 fb-1. We also compare the displaced vertex reaches of the LHC and Tevatron.
