Neutrinos as a probe of dark-matter particles

TL;DR

This paper explores the potential of neutrinos, particularly right-handed ones, as probes for dark-matter particles within an extended Standard Model framework that includes additional gauge symmetries.

Contribution

It proposes a new model extending the Standard Model with additional gauge groups and introduces principles to guide the search for dark-matter interactions involving neutrinos.

Findings

Neutrinos may directly couple with dark-matter particles.

A specific extended Standard Model framework is proposed.

Guidelines for future dark-matter and neutrino interaction searches.

Abstract

We try to envision that there might be a dark-matter world and neutrinos, especially the right-handed ones, might be coupled directly with dark-matter particles in the dark-matter world. The candidate model would be the extended Standard Model based on SU_c(3)\times SU_L(2)\times U(1)\times SU_f (3)\times SU_R(2), with the search of the detailed version through the aid of the two working rules, "Dirac similarity principle" and "minimum Higgs hypothesis".
