The light quark coupling of the E(38) boson candidate

TL;DR

This paper estimates the coupling constant of the E(38) boson candidate to light quarks, assuming it is produced via bremsstrahlung and decays solely into two photons, providing insight into its interaction strength.

Contribution

It introduces an estimation method for the light quark coupling of the E(38) boson based on production and decay assumptions.

Findings

Coupling constant to light quarks is approximately 10^{-4}

Production assumed to be bremsstrahlung-like

Decay limited to two photons

Abstract

Assuming that the E(38) boson candidate recently observed at the JINR Nuclotron is produced in a bremsstrahlung-like manner and decays only to two photons, its coupling constant to light quarks is estimated to be $\sim 10^{-4}$.
