Considerations on Xi- reconstruction in LHCb

TL;DR

This paper presents a new method for reconstructing charged hyperons in the LHCb experiment, improving efficiency by addressing previous ambiguities and adapting techniques from earlier research to LHCb's detector layout.

Contribution

It introduces an alternative Xi- reconstruction method tailored for LHCb, extending prior work and resolving earlier ambiguities to enhance decay reconstruction efficiency.

Findings

Improved reconstruction efficiency for Xi- and Omega- baryons.

Addressed and resolved reconstruction ambiguities from previous methods.

Extended FOCUS collaboration techniques to LHCb detector layout.

Abstract

This paper describes an alternative method of charged hyperon reconstruction applicable to the LHCb experiment. It extends the seminal work of the FOCUS collaboration to the specific detector layout of LHCb and addresses the reconstruction ambiguities reported in their earlier work, leading to improvements in the reconstruction efficiency for the specific cases of Xi- and Omega- baryon decays to a charged meson and a Lambda baryon.
