Higgs effective field theory

WebIn physics, specifically field theory and particle physics, the Proca action describes a massive spin -1 field of mass m in Minkowski spacetime. The corresponding equation is a relativistic wave equation called the Proca equation. [1] The Proca action and equation are named after Romanian physicist Alexandru Proca .
