A first look at data from the NO$\nu$A upward-going muon trigger
Abstract
The NOA collaboration has constructed a 14,000 ton, fine-grained, low-Z, total absorption tracking calorimeter at an off-axis angle to an upgraded NuMI neutrino beam. This detector, with its excellent granularity and energy resolution and relatively low-energy neutrino thresholds, was designed to observe electron neutrino appearance in a muon neutrino beam, but it also has unique capabilities suitable for more exotic efforts. In fact, if sufficient cosmic ray background rejection can be demonstrated, NOA will be capable of a competitive indirect dark matter search for low-mass Weakly-Interacting Massive Particles (WIMPs). The cosmic ray muon rate at the NOA far detector is approximately 100 kHz and provides the primary challenge for triggering and optimizing such a search analysis. The status of the NOA upward-going muon trigger and a first look at the triggered sample is presented.
