Improved precision in inverse beta decay cross section
arXiv:2502.17343
Abstract
We analyze the cross section for inverse beta decay, focusing on the moderate energies (a few MeV to hundreds of MeV) relevant for reactor and supernova neutrinos. We discuss the updated evaluations of values and uncertainties in the cross section, and the effect of second-class currents. The estimate of theoretical precision is important for current and future experiments, when large data samples are or become available.
