Marat Siddikov, Ivan Schmidt
TL;DR
This paper calculates next-to-leading order corrections to neutrino-induced pion and kaon production, showing they significantly increase cross-sections and providing a computational tool for accurate predictions in experiments.
Contribution
It introduces the first detailed estimation of NLO corrections for neutrino-induced meson production and offers a versatile code for cross-section evaluation with different GPD models.
Findings
NLO corrections can double the leading order cross-section.
Corrections are sizable in the Minerva experiment kinematics.
A code for cross-section calculation including these corrections is provided.
Abstract
In this paper we study the next-to-leading order corrections to deeply virtual pion and kaon production in neutrino experiments. We estimate these corrections in the kinematics of the Minerva experiment at FERMILAB, and find that they are sizable and increase the leading order cross-section by up to a factor of two. We provide a code, which can be used for the evaluation of the cross-sections, taking into account these corrections and employing various GPD models.
