Diboson physics at the Tevatron

Abstract

Measurements of diboson events in proton-antiproton collisions at $\sqrt{s}=1.96$ TeV are effective probes of the electro-weak gauge structure in the Standard Model (SM). Due to the potentially high energy scale in the collisions, bosonic operators beyond the leading order in the Lagrangian become important at the Tevatron and make the theoretical interpretations non trivial. The fact that we need cut-offs in our models in order to maintain unitarity underline the importance of direct measurements at the highest possible energy scales. I report on two new such measurement from CDF and compare to similar D0 results taken at lower integrated luminosities.
