Data handling with SAM and art at the NOνA experiment
During operations, NOvA produces between 5,000 and 7,000 raw files per day with peaks in excess of 12,000. These files must be processed in several stages to produce fully calibrated and reconstructed analysis files. In addition, many simulated neutrino interactions must be produced and processed through the same stages as data. To accommodate the large volume of data and Monte Carlo, productio...
متن کاملSuper-NOνA: A Long-baseline Neutrino Experiment with Two Off-axis Detectors
We consider here the NOνA experiment configuration and propose to place a second off-axis detector, with a shorter baseline, such that the type of neutrino mass hierarchy could be determined, by exploiting matter effects, with only the neutrino run. We show that the determination of this parameter is free of degeneracies, provided the ratio L E, where L the baseline and E is the neutrino energy...
متن کاملGetting the most from NOνA and T2K
The determination of the ordering of the neutrino masses (the hierarchy) is probably a crucial prerequisite to understand the origin of lepton masses and mixings and to establish their relationship to the analogous properties in the quark sector. In this talk, we follow an alternative strategy to the usual neutrino–antineutrino comparison: we exploit the combination of the neutrino-only data fr...
متن کاملResults from MINOS and NOνA
The MINOS experiment, operating in the NuMI beam since 2005, has provided the most precise measurement of the atmospheric mass splitting |∆m232|, and the recent combination of the νμ, νe, and atmospheric neutrino samples has provided some evidence of non-maximal mixing, and hints about the neutrino mass hierarchy and the θ23 octant. Construction of the NOνA experiment, situated off-axis in the ...
متن کاملLibrary Event Matching event classification algorithm for electron neutrino interactions in the NOνA detectors
We describe the Library Event Matching classification algorithm implemented for use in the NOνA νμ → νe oscillation measurement. Library Event Matching, developed in a different form by the earlier MINOS experiment, is a powerful approach in which input trial events are compared to a large library of simulated events to find those that best match the input event. A key feature of the algorithm ...
