Searches for New Physics with the ALICE Experiment in pp Collisions

TL;DR

This paper evaluates ALICE detector capabilities in searching for new heavy stable charged particles, using gluino R-hadrons as a case study with simulations to assess detection prospects in proton-proton collisions.

Contribution

It presents a detailed simulation-based analysis of the ALICE detector's performance in detecting heavy stable charged particles, focusing on gluino R-hadrons in pp collisions.

Findings

Cross sections and kinematic properties for gluino R-hadrons were obtained from PYTHIA simulations.

Detector response simulations indicate the ALICE detector's sensitivity to R-hadrons within the specified acceptance.

The study provides a framework for future experimental searches for new physics with ALICE.

Abstract

The performance of the ALICE detector in searches for new heavy stable charged particles in pp collisions is discussed in this paper. Gluino R-hadron was chosen as an example of a candidate, and cross sections and kinematic properties were obtained from PYTHIA simulations for various gluino masses ($100-500 GeV/c^2$). Detector response simulations for R-hadrons in the TPC acceptance ($|\eta|<1$) were performed for $100 GeV/c^2$ R-hadron mass.
