Quark decay top to two bodies

Abstract

Is investigated the top quark decay (t) two bodies using the spectator model. Is analyzed the decay (t→bW⁺) calculated theoretically the width of decay and decay fraction of the particle whose result is compared with the experimental data of the table Particle Data group. The model prediction on the decay process can be considered good as a first approach to this class of decay. This type of analysis is particularly important because it allows one hand, familiarize students with the decays of particles and on the other, open a space to introduce topics of particle physics in the introductory courses at university level.
