Contribution

It introduces a simple Froggatt-Nielsen framework with minimal new particles to address several anomalies and neutrino mass generation.

Findings

Successfully explains B physics anomalies R_K and R_D

Generates naturally light neutrino masses

Accounts for the 750 GeV diphoton excess

Abstract

Vector leptoquarks provide an elegant solution to a series of anomalies and at the same time generate naturally light neutrino masses through their mixing with the standard model Higgs boson. We present a simple Froggatt-Nielsen model to accommodate the B physics anomalies $R_K$ and $R_D$, neutrino masses, and the $750$ GeV diphoton excess in one cohesive framework adding only two vector leptoquarks and two singlet scalar fields to the standard model field content.
