On the W mass and new Higgs bosons
We discuss the prediction of the W boson mass in a simple extension of the Standard Model (ΣSM) with a real scalar triplet. A shift in the W mass as reported by the CDF II collaboration can naturally be accommodated by the model without modifying the Standard Model value for the Z mass. We discuss the main implications and the properties of the new Higgs bosons. Namely, the partial decay widths of the new charged Higgs are predicted. Furthermore, the neutral Higgs has suppressed couplings to fermions and decays predominantly into a pair of W gauge bosons.
