Research output: Contribution to journalArticlepeer-review

Abstract

A derivation of the effective Lagrangian for non-relativistic quantum chromodynamics and the heavy quarks effective field theory is given. Our calculation provides a simple and systematic method of calculation of the full off-shell effective Lagrangian at tree level including all the 1/m corrections.
