Description
The tau lepton plays a crucial role in studying the Standard Model, providing access to the Higgs and leptonic sectors of physics. Unlike other proposed future collider experiments, a muon collider has the potential to reach high center of mass energies with colliding leptons, which are fundamental particles, ensuring that the totality of the beam energy is available for the production of new particles, such as taus. However, the inherent instability of muons poses significant challenges in detector design and particle reconstruction for this machine. Muon decays generate substantial beam-induced background (BIB), dominated by soft secondary particles which can obscure collision products in the detector volume. Regardless of the environment, tau reconstruction is already challenging to perform due to the fact that the taus decay before reaching the detector region and must be reconstructed through their decay products, approximately 65% of which are hadronic. Tau reconstruction has been investigated for a 3 TeV muon collider, but no dedicated study exists for a 10 TeV machine. In this study, we assess the performance of the $\texttt{TauFinder}$ reconstruction algorithm in the MAIA (Muon Accelerator Instrumented Apparatus) detector geometry, intended for $\sqrt{s} = 10$ TeV $\mu^+\mu^-$ collisions. We evaluate the reconstruction efficiency of one-prong and three-prong hadronically decaying taus. Our results provide a benchmark performance of tau reconstruction in a 10 TeV muon collider, demonstrating the physics potential of this machine.
