Proton Spin and Tensorgluons

TL;DR

This paper explores the potential role of hypothetical tensorgluons, which carry larger spin, in the nucleon’s spin structure, suggesting they could significantly influence the nucleon spin through their polarized density.

Contribution

It introduces the concept of tensorgluons as additional partons inside hadrons and analyzes their possible impact on the nucleon spin, a novel idea in hadronic physics.

Findings

Tensorgluons can carry a significant fraction of nucleon momentum.

Polarized tensorgluon density can influence nucleon spin structure.

Tensorgluons may provide a screening effect due to their larger spin.

Abstract

Recently it was suggested that inside the hadrons there are additional partons - tensorgluons - which carry the same charges as the gluons, but have larger spin. The nonzero density of tensorgluons can be created inside a nucleon by radiation of tensorgluons by gluons. Tensorgluons can carry a part of nucleon momentum together with gluons. Because tensorgluons have a larger spin, they can influence the spin structure of the nucleon. We analyse a possible contribution of polarised tensorgluon density to the spin of the nucleon. This contribution appears in the next to leading order, compared to the gluons and can provide a substantial screening effect due to the larger spin of tensorgluons.
