CDF Wjj anomaly as a non-perturbative effect of the electro-weak interaction

TL;DR

This paper proposes that the CDF Wjj anomaly can be explained by a non-perturbative bound state of W bosons resulting from an anomalous three-boson interaction, aligning with observed data without adjustable parameters.

Contribution

It introduces a non-perturbative approach using Bogoliubov compensation to explain the W boson bound state causing the anomaly, a novel theoretical perspective.

Findings

Bound state mass estimated at 145 GeV.

Agreement with experimental data achieved without adjustable parameters.

Provides a non-perturbative explanation for the CDF anomaly.

Abstract

The recently reported CDF excess at $120\,-\, 160\,GeV$ in invariant mass distribution of jet pairs accompanying $W$-boson is tentatively interpreted as a bound state of two $W$ decaying to quark-anti-quark pair. Non-perturbative effects of EW interaction obtained by application of Bogoliubov compensation approach lead to such bound state due to existence of anomalous three-boson gauge-invariant effective interaction. The application of this scheme gives satisfactory agreement with existing data without any adjusting parameter but the bound state mass $145\,GeV$.
