The existence of the magnetic monopole has eluded physicists for centuries. The NOvA Far Detector (FD), used for neutrino oscillation searches, also has the ability to identify magnetic monopoles. With a surface area of 4,100 m2 and a location near the earth’s surface, the 14 kt FD provides us with the unique opportunity to be sensitive to potential low-mass monopoles unable to penetrate underground experiments. We have designed a novel data-driven triggering scheme that continuously searches the FD’s live data for monopole-like patterns. At the offline level, the largest challenge in reconstructing monopoles is to reduce the 148,000 Hz speed-of-light cosmic ray background. In the absence of any signal events in a 95-day exposure of the FD, we set limits on the monopole flux of 2×10−14cm−2s−1sr−1 at 90% C.L. for monopole speed 6×10−4<β<5×10−3 and mass greater than 5×108 GeV. In this talk, I will review the current monopole results and discuss the sensitivities of future searches using more than 8 years of collected FD data. – (Proceedings of Science ; Vol. 449) .
