Physics Colloquium with Jaehoon Yu on DAMSA, A Novel Dark Matter Search Experiment

Neutrinos make up a quarter of the elementary particle map in the Standard Model of particle physics. They, however, do not behave as the Standard Model predicted.  Thus, the model needs to be modified for it to have the predictive power. Future neutrino experiments, such as the Deep Underground Neutrino Experiment (DUNE) at Fermilab near Chicago aims to precisely measure neutrino properties to accomplish this goal.  They use high flux neutrino beams produced from the proton interactions on a target and a powerful combination of detectors for the precision measurements.

Fermilab's PIP-II LINAC is an essential element in providing the necessary high flux proton beams to DUNE.  Thanks to the powerful beams, this facility can also shed lights on the dark matter thought to make up about 25% of the universe.   Discovering the dark matter at an accelerator will enable detailed studies of its properties.  In this talk, I will briefly describe DUNE and the recently proposed concept of the Dump produced Aboriginal Matter Search at Accelerators (DAMSA).  I will also discuss current status and plan for DAMSA and its expected sensitivity reach in the search for Axion-Like Particle, a dak sector particle.
