Good 𝜈's: Neutrino Physics at a Muon Collider

US/Eastern
Description

Workshop Goals & Scope:  

The workshop will bring together experts in neutrino physics and high-energy colliders to explore the unique opportunities that a high-energy muon collider offers in answering key neutrino-related questions. The primary focus will be identifying questions that cannot be addressed by current or near-future experiments, with an emphasis on exploring new physics through neutrino interactions at such a collider.

The workshop will involve contributions from both neutrino and collider physicists as well as machine experts, who will collaborate to assess the need for a dedicated neutrino detector and investigate how high-energy neutrinos from muon decay could help address broader questions in the main detector. The discussions and outcomes of the workshop will be concluded in a white paper. The white paper will summarize the key findings, possible neutrino-related measurements, and design considerations for the collider, including the potential for incorporating a neutrino factory. This workshop, which will be first in this topic, will serve as a hub for the community, fostering collaborations that could shape the future of neutrino studies at high-energy muon colliders.
