Exclusive proton final-states and kinematic imbalance in differential neutrino cross-sections with the MicroBooNE detector

Friday 9 Jun 2023, 16:00 → 17:00 US/Central

This is the so-called “Wine and Cheese” seminar.

Code of conduct: The Wine and Cheese is a scientific seminar and thus questions and discussion are welcome. The goal of discussion is to enhance the quality and understanding of the science for the whole community. Out of consideration for all, even when questions are not straightforward, we will insist that they be asked and answered with respect and civility. We value voices of all backgrounds, accents, pitches and degrees of softness, both among our speakers and in the audience. Scientific claims are judged by their content and rigor, and not by the demeanor of their proponent

16:00 → 17:00 Exclusive proton final-states and kinematic imbalance in differential neutrino cross-sections with the MicroBooNE detector

Making high-precision measurements of neutrino oscillation parameters requires an unprecedented understanding of neutrino-nucleus scattering. In today’s seminar, we demonstrate how we push towards this high-precision era by presenting two differential cross section measurements using neutrino data sets from the MicroBooNE detector.

In the first part, we report on the first charged current single- and double-differential cross sections in kinematic imbalance variables on argon. We use events with a single muon, a single final state proton, and no final state pions recorded by the MicroBooNE liquid argon time projection chamber detector. These variables characterize the missing momentum in the plane transverse to an incoming neutrino. Thus, they act as a direct probe of nuclear effects such as final state interactions, Fermi motion, and multi-nucleon processes.

In the second part, we present the first cross-section measurement for the production of 2 particle-2 hole (2p2h) states on argon. These interactions produce a topology with one muon and two protons in the final state (CC1μ2p0π). This analysis reports a single differential cross-section measurement for CC1μ2p0π event topologies in a variety of kinematic variables. Comparisons are made to a set of theoretical models that explore different cross-section modeling configurations.
