TL;DR

This paper investigates how finite lattice sizes affect nucleon mass calculations in dynamical QCD, using lattice simulations and chiral perturbation theory to predict these effects.

Contribution

It provides a quantitative analysis of finite size effects on nucleon masses in dynamical lattice QCD using one-loop chiral perturbation theory.

Findings

Finite size effects are significant for light dynamical quarks.

Predictions align with lattice simulation results.

Finite size corrections can be estimated using chiral perturbation theory.

Abstract

For lattice calculations with light dynamical quarks, finite size effects have become an important aspect. We study finite size effects in nucleon masses on N_f=2 dynamical lattices of 1-2 fm. Predictions for the finite size effects are obtained in one-loop chiral perturbation theory.
