Description
Motivated by the Reactor Anti-neutrino Anomaly (RAA, an experimental 6% flux deficit),
recent reactor anti-neutrino experiments have explored the existence of
a fourth, sterile neutrino. Its experimental signature is oscillations
induced over short baselines. The STEREO and PROSPECT experiments have
excluded the RAA’s best-fit oscillation parameters at over 4σ and
produced exclusions contours for other areas of the parameter space.
A joint analysis combining STEREO, PROSPECT, and Daya Bay is currently
underway to improve the exclusion contours.
This talk will present my work in this context on reproducing STEREO
Phase 2 results, focusing on numerical optimizations to improve
computational efficiency. I will also discuss the development of an
analytical response model, used to enhance flexibility in fitting
procedures and better handle systematic uncertainties.
