MINERvA

Group Leaders:

MINERvA, or Main INjector ExpeRiment for v-A, at Fermilab is an experiment dedicated to the study of neutrino-nucleus interactions in the GeV regime. Its goal is to illustrate the interplay between hadronic and nuclear physics and measure intranuclear dynamics that are crucial for the present and future neutrino oscillation measurements.

As the analysis of the Low-Energy data—the \nu_{\mu}/\overline{\nu}_{\mu} beam flux peaks at about 3 GeV with most of the rate between 1-6 GeV—has come to a conclusion, nuclear effects are shown to be a complex phenomenon which challenges many of the popular theoretical descriptions. Recently, MINERvA has completed its physics run with the Medium-Energy (flux peak at 6 GeV) beam. The experiment received a total of 12×1020 protons on target in both neutrino and antineutrino mode running, which allow for a new level of statistical precision in neutrino interaction measurements, both in comparisons of interaction channels on a range of nuclei and in expansion to kinematic phase space that has not been accessible in previous data sets.

The Oxford Group in MINERvA was established in 2016, and is pioneering the measurements of transverse kinematic imbalance, or TKI, in neutrino-nucleus interactions. Recent highlights include Phys. Rev. D 102, 072007 (2020), Phys. Rev. D 101, 092001 (2020), and Phys. Rev. Lett. 121, 022504 (2018), that systematically explore the potential of TKI in identifying the medium properties and interaction dynamics in exclusive processes.
