Description
Neutrinos constitute a powerful probe for determining Parton Distribution Functions (PDFs), owing to their flavor-dependent interactions with quarks. Historically, neutrino measurements have been limited, in part, by low statistics. However, recent experimental developments are opening a new era of high-statistics neutrino–nucleus interaction measurements with enhanced final-state reconstruction capabilities, as exemplified by the Deep Underground Neutrino Experiment (DUNE). These measurements could, for example, assess emerging tensions between neutrino–nucleon and charged lepton–nucleon deep inelastic scattering (DIS) data, that potentially point toward neutrino-specific nuclear effects. In this work, we assess the potential impact of future DUNE data on improving state-of-the-art PDF determinations. Preliminary results show improvements, specially in nuclear effects.
In addition, we find that if final-state events with a charm meson can be identified, DUNE would be particularly sensitive to the strange-quark PDF.
