Sensitivity to Cabibbo-Suppressed $\Lambda$ Production in MicroBooNE
None None, USDOE Office of Science (SC), High Energy Physics (HEP) · 2022
We present a procedure to measure a flux averaged, restricted phase space cross section for direct (Cabibbo suppressed) Λ production using the MicroBooNE detector.This is a rare process, exclusively occurring in anti-neutrino interactions and to maximise the sensitivity of this analysis we combine predictions using the NuMI flux from two data taking periods, one in which this beam was run in neutrino mode and one in anti-neutrino mode.The event selection for this analysis was previously described in MicroBooNE public note 1097 [1].The calculation of systematic uncertainties is shown and a method to propagate them through to the final cross section calculation is described, with final sensitivities shown in the form of Bayesian posterior distributions on the extracted cross section.
