TL;DR
This paper calculates how finite size effects influence nucleon masses using relativistic chiral perturbation theory and compares these results with two-flavor lattice QCD data.
Contribution
It introduces a method to quantify finite size effects on nucleon masses within chiral perturbation theory and validates it against lattice QCD results.
Findings
Finite size effects can significantly impact nucleon mass calculations.
Relativistic chiral perturbation theory accurately predicts finite size effects.
Comparison shows good agreement with lattice QCD data.
Abstract
The finite size effects on nucleon masses are calculated in relativistic chiral perturbation theory. Results are compared with two-flavor lattice results.
