Structure functions near the chiral limit

TL;DR

This paper calculates hadron masses and nucleon structure function moments at low pion masses to accurately predict physical light quark behavior.

Contribution

It provides new computations approaching the physical light quark mass, reducing uncertainties in hadron structure predictions.

Findings

Hadron masses computed near the physical pion mass.

Lowest moments of structure functions determined at low pion masses.

Predictions made closer to physical quark masses.

Abstract

We compute hadron masses and the lowest moments of unpolarized and polarized nucleon structure functions down to pion masses of 300 MeV, in an effort to make unambiguous predictions at the physical light quark mass.
