Hadron Structure on the Lattice

TL;DR

This paper reviews lattice QCD calculations of key nucleon properties, including form factors, scalar content, and parity-violating effects, highlighting their current status and phenomenological relevance.

Contribution

It provides a comprehensive overview of recent lattice QCD results on nucleon structure and discusses their implications for particle physics phenomenology.

Findings

Lattice calculations of the nucleon sigma term and scalar strangeness are summarized.

Results on vector and axial form factors, including strangeness contributions, are presented.

The paper discusses the status and potential impact of these lattice studies on phenomenology.

Abstract

A few chosen nucleon properties are described from a lattice QCD perspective: the nucleon sigma term and the scalar strangeness in the nucleon; the vector form factors in the nucleon, including the vector strangeness contribution, as well as parity breaking effects like the anapole and electric dipole moment; and finally the axial and tensor charges of the nucleon. The status of the lattice calculations is presented and their potential impact on phenomenology is discussed.
