Multi-track reconstruction algorithms in the Mu2e experiment

Key Points

Efficient tracking algorithms reconstruct multiple particle events, enhancing data analysis in the Mu2e experiment.
Algorithms were specifically developed to address background noise from p¯-annihilation in the Al target.
The Mu2e experiment aims to discover neutrino-less conversion, with greater accuracy provided by multi-track reconstruction techniques.
Research supports the search for processes beyond the standard model, providing broader implications for particle physics.

Abstract

The Mu2e experiment, under construction at Fermilab, will search for the neutrino-less coherent µ − N → e − N conversion in the field of a 27 Al nucleus, a CLFV process. While the main goal of the experiment is to reconstruct the conversion electron, i.e., an event with a single track, there are motivations to develop an efficient tracking algorithm for reconstructing more simultaneous tracks. This could better constrain the background generated by p¯ -annihilation in the Al target and search for Beyond the Standard Model processes. In this paper, we present the algorithms designed to reconstruct multi-particle events.
