• “Nucleon binding energy and transverse momentum imbalance in neutrino-nucleus reactions”, T. Cai et al [MINERvA Collaboration], Phys. Rev. D 101, 092001.
  Using ideas from previous work by PhD student Tejin Cai and Professor Arie Bodek, and experimental techniques from Postdoctoral fellow Dan Ruterbories, Tejin has made a measurement of kinematic imbalance that is sensitive to how bound nucleons are inside the carbon nucleus. This result is used in postdoctoral fellow Clarence Wret’s work on T2K which needs to correct for this in its energy estimation.
• “Constraint on the matter–antimatter symmetry-violating phase in neutrino oscillations”, K. Abe et al [T2K Collaboration], Nature 580 (2020) 7803, 339-344.
  T2K data favors differences in neutrino-antineutrino oscillations at almost three standard deviation significance. We knocked COVID-19 off the cover of Nature that week! Marshak Postdoctoral Fellow Clarence Wret is one of the oscillation working group conveners and plays a critical role in the near detector fit that controls uncertainties in the analysis.
• “Neutrino-electron elastic scattering for flux determination at the DUNE oscillation experiment”, Chris M. Marshall, Kevin S. McFarland, Callum Wilkinson, Phys. Rev. D 101 (2020) 3, 032002.
  Chris Marshall and Kevin McFarland teamed up with former Rochester visiting student Callum Wilkinson to study how precision neutrino-electron scattering measurements could be used to constrain the neutrino flux at DUNE.
• “High-Statistics Measurement of Neutrino Quasielastic-like Scattering at 6 GeV on a Hydrocarbon Target”, M.F. Carneiro, D. Ruterbories et al, [MINERvA Collaboration], Phys.Rev.Lett. 124 (2020) 12, 121801.
  The first of many measurements of quasielastic scattering at MINERvA using techniques developed by postdoctoral researcher Dan Ruterbories. This paper finds evidence for some unexpected nuclear effects at low Q², and deviations from the dipole axial form factors at high Q².
