Prospects for detecting axionlike particles at the Coherent CAPTAIN-Mills experiment
Prospects for detecting axionlike particles at the Coherent CAPTAIN-Mills experiment
We show results from the Coherent CAPTAIN Mills (CCM) 2019 engineering run which begin to constrain regions of parameter space for axion-like particles (ALPs) produced in electromagnetic particle showers in an 800 MeV proton beam dump, and further investigate the sensitivity of ongoing data-taking campaigns for the CCM200 upgraded detector. …
