Description
The NOvA experiment is designed to study accelerator neutrino oscillations. However, due to the unique design of its detectors (large size, high segmentation) and the flexibility of its data acquisition system configuration, NOvA also provides opportunities for investigating atmospheric neutrinos. Nevertheless, the experiment currently lacks a dedicated trigger for selecting such events.
The primary data-taking phase of the NOvA experiment is scheduled to conclude in 2027. This creates a limited time window for developing and implementing new event selection methods.
This work presents a developed trigger algorithm capable of identifying both track-like and cascade-like (non-track) events characteristic of atmospheric neutrino interactions. Estimates of the algorithm's performance efficiency based on Monte Carlo simulation are provided, along with results from testing on previously collected unbiased NOvA experimental data.
