# Binding Energies in Nonrelativistic Field Theories

## TL;DR

This paper reviews how relativistic corrections relate the binding energy of bound states to their kinetic mass, explaining anomalies observed in heavy-light mesons and quarkonia.

## Contribution

It provides a review of the mechanism connecting binding energy and kinetic mass, clarifying previously observed anomalous results in lattice QCD studies.

## Key findings

- Relativistic corrections link binding energy to kinetic mass.
- Explanation of anomalies in heavy-light mesons and quarkonia.
- Clarification of previous lattice QCD results.

## Abstract

Relativistic corrections communicate the binding energy of a bound state to its kinetic mass. This mechanism is reviewed and used to explain anomalous results of Collins, Edwards, Heller, and Sloan (hep-lat/9512026), which compared rest and kinetic masses of heavy-light mesons and quarkonia.
