Unveiling the seasonal variation of multi-muon events at the NOvA Detector

Popis výsledku v původním jazyce

In this contribution, we investigate the seasonal variation of multi-muon events observed by the NOνA Near Detector (ND), using the general-purpose Monte Carlo code FLUKA-CERN to simulate the transport and interaction of the air-shower particles in the atmosphere and other media. Our atmospheric model uses air densities for Winter and Summer averaged profiles calculated from the temperature and geopotential information at 37 pressure levels given by the European Center for Medium-Range Weather Forecasts datasets in situ. Our FLUKA geometry model also includes a layered underground approximated to match the NOνA~ND and its location. We compare our simulation results with the measured seasonal flux modulation of multi-muon events by the NOνA~ND. For the first time, we were able to describe the multi-muon excess in Winter over Summer quantitatively and the dependence on the multi-muon event multiplicity as observed by NOνA.
