TL;DR

This paper develops a microscopic SU(3) chiral Lagrangian model to study strange particle production off nucleons induced by neutrinos and antineutrinos at low to intermediate energies, predicting measurable cross sections.

Contribution

It introduces a novel microscopic model based on SU(3) chiral Lagrangian for strange particle production in neutrino interactions.

Findings

Main mechanisms dominate single kaon production up to 1.5 GeV

Cross sections are sizable for experimental detection

Model applicable to experiments like MINERvA, T2K, NOvA

Abstract

The strange particle production off the nucleon induced by neutrinos and antineutrinos is investigated at low and intermediate energies. We develop a microscopic model based on the SU(3) chiral Lagrangian. The studied mechanisms are the main source of single kaon production for (anti)neutrino energies up to 1.5 GeV. Using this model we have also studied the associated production of kaons and hyperons. The cross sections are large enough to be measured by experiments such as MINER$\nu$A, T2K and NO$\nu$A.
