Is the charged vecton boson seen by the CDF II the standard model one?

TL;DR

This paper examines whether the CDF II observed charged vector bosons align with the standard model or suggest new physics, proposing an extended gauge symmetry model that can accommodate the observed mass.

Contribution

It introduces an electroweak model with extended gauge symmetry that can explain the CDF II charged boson mass at tree level.

Findings

The model can fit the CDF II charged boson mass at tree level.

Predicts a shift in the neutral vector boson mass in some model variants.

Provides a framework for interpreting CDF II results within extended gauge theories.

Abstract

After the CDF II results, we can ask ourselves, have they observed the vector boson $W$ of the standard model? or have they discovered the effect of new physics? We show that, in electroweak models with $SU(2)_L\otimes SU(2)_R\otimes U(1)_{B-L}$ gauge symmetry, it is possible to accommodate, at tree level, the value of the mass of the charged vector boson obtained by the CDF-II. A shift in the mass of the lightest neutral vector boson is also predicted in some versions of the model.
