Multi-strange baryon measurements at LHC energies, with the ALICE experiment

TL;DR

This paper reports on measurements of multi-strange baryons at LHC energies using the ALICE experiment, focusing on early proton-proton collision data at 0.9 and 7 TeV, highlighting the cascade-decay analysis method.

Contribution

It presents the first results of multi-strange baryon spectra at LHC energies using ALICE, emphasizing the cascade-decay topology and early data analysis.

Findings

Uncorrected pT-spectra for Xi and Omega baryons at 0.9 and 7 TeV

Use of cascade-decay topology for baryon identification

Focus on early pp data-taking period (2009-2010)

Abstract

The status of the charged multi-strange baryon analysis (Xi-, anti-Xi+, Omega-, anti-Omega+) at LHC energies is presented. This report is based on the results obtained with ALICE (A Large Ion Collider Experiment), profiting from the characteristic cascade-decay topology. A special attention is drawn to the early pp data-taking period (2009-2010) and subsequently, on the uncorrected pT-spectra extracted at mid-rapidity for centre of mass energies of 0.9 TeV and 7 TeV.
