Diboson physics at the Tevatron

TL;DR

This paper discusses measurements of diboson production at the Tevatron collider, which test the electroweak sector of the Standard Model and explore potential new physics at high energies.

Contribution

It presents new measurements of diboson events from CDF and compares them with D0 results, highlighting the importance of direct high-energy probes for understanding electroweak interactions.

Findings

Measurements are consistent with Standard Model predictions.

High-energy data constrains anomalous gauge couplings.

Results emphasize the need for direct measurements at Tevatron energies.

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.
