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

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 \(145\,GeV\).
