WP2: Physics and Detectors Requirements


WP2 will be coordinated by UNIPD, with the participation of INFN, CEA, DESY, UOS, LIP, CERN, ISU, SYSU, and UNIPV.


WP2 will study the beam-induced background effects on the detector with different interaction region design to define its optimal configuration which will include the shielding. Event reconstruction algorithms will be developed to exploit 5D information in order to additionally mitigate the beam-induced background effects, in particular the irreducible part. 

The last objective is the detector performance evaluation by using the most relevant SM measurements and New Physics reaches.


Task 2.1

Design of detector configurations at √s=3 TeV and √s=10 TeV with the optimised interaction regions (UNIPD).

This task will study the beam-induced background effects on the detector components produced with different interaction region configurations. Feedbacks will be given to WP5, high energy complex, where the IR is designed to optimise background fluxes and the shielding configuration. This will be done in an iterative way until an optimised IR is defined and the relative detector configuration proposed.

Task 2.2

Design and implementation of event reconstruction algorithms in 5D at √s=3 TeV and √s=10 TeV (DESY).

This task will focus on developing reconstruction algorithms exploiting 3D position, energy, and timing measurements to mitigate beam-induced background and perform tracking and calorimetry clustering. Leveraging on the developments made for future colliders, this task will explore machine learning solutions and parallel computing, both for real-time event processing and for offline analysis, taking into account the specific challenges of a muon collider (e.g., particle tracking in the forward region).

Task 2.3

Evaluate detector performance at different collision energies by using major physics processes (INFN).

This task will explore the detector performance of a muon collider operating at different collision energies. Exploiting an optimal design of the interaction region (Task1) and advances in event reconstruction (Task2), the detector performance will be determined by evaluating the reach of major physics processes for Standard Model measurements, and for searches for physics beyond the Standard Model.
