Subluminal Magnetic Monopole Search with NO$\nu$A

ORAL

Abstract

The existence of the magnetic monopole has eluded physicists for centuries. The NO$\nu$A far detector (FD), used for neutrino oscillation searches, has the additional capability to search for magnetic monopoles at subluminal velocities. With a surface area of over 4,000~m$^2$ and a location near the earth's surface, the 14~kT FD provides us with the unique opportunity to explore an area of magnetic monopole phase space previously inaccessible to underground experiments. We have designed a novel data-driven triggering scheme that continuously searches the FD's live data for monopole-like structures. At the offline level, the largest challenge in reconstructing monopoles is to reduce the 148,000~Hz speed-of-light cosmic ray background. In this talk, I will present the trigger algorithm that we employ and the offline reconstruction algorithm that will be used for the first NO$\nu$A monopole search.
