Introdução ao modelo padrão de Física de partículas: construção da lagrangiana do setor de léptons sem massa da interação eletrofraca

Abstract

In this current work, we are going to introduce a systematic method for building up the Lagrangian of the massless lepton sector of the Electroweak interaction within standard model of particle physics. Starting off doing a ”brief”comment about the particles in which such theory holds. In the following sections, we’ll stamble upon with Lie Groups and classical fields (such as scalar, vectorial, tensorial and spinorial fields). For making out, we’ll make the Lagrangian using a direct application of the previous concepts developed through this work.
