<b>Abstract: </b>A clear
outcome of Snowmass 2021 was the
community support for R&D
towards a future muon collider.
We propose a new beam dump
experiment at a future TeV-scale
muon collider, and the
demonstrator facilities along
the way. A beam dump would be an
economical and effective way to
increase the discovery potential
of the collider complex in a
complementary regime. In this
work we consider vector models
such as the dark photon and
Lμ−Lτ gauge boson as new physics
candidates and explore which
novel regions of parameter space
can be probed with a muon beam
dump. We find that, at the full
center of mass energies, for the
dark photon model, we gain
sensitivity in the moderate mass
(MeV - GeV) range at both higher
and lower couplings compared to
existing and proposed
experiments, and gain access to
previously untouched areas of
parameter space of the Lμ−Lτ
model. In this talk, we will
also cover the basics towards
the feasibility of a muon
collider, as well as the physics
potential at various
demonstrator facilities on the
way to R&D for the full 10+
TeV collider.<br>
