Flavor Changing Neutral Currents in the Asymmetric Left-Right Gauge Model

TL;DR

This paper investigates flavor changing neutral currents within an asymmetric left-right gauge model, analyzing how scalar sector constraints align with recent experimental data to inform new physics beyond the Standard Model.

Contribution

It provides a detailed analysis of FCNC constraints in a minimal asymmetric scalar sector of the left-right model, connecting theoretical predictions with current experimental limits.

Findings

Constraints on scalar-mediated FCNC are consistent with recent data.

The minimal scalar sector can accommodate neutrino mass and dark matter.

Implications for new physics searches are discussed.

Abstract

In the $SU(3)_C \times SU(2)_L \times SU(2)_R \times U(1)_{(B-L)/2}$ extension of the standard model, a minimal (but asymmetric) scalar sector consists of one $SU(2)_R \times U(1)_{(B-L)/2}$ doublet and one $SU(2)_L \times SU(2)_R$ bidoublet. Previous and recent studies have shown that this choice is useful for understanding neutrino mass as well as dark matter. The constraints from flavor changing neutral currents mediated by the scalar sector are discussed in the context of the latest experimental data.
