Unformatted text preview: their masses in terms of the gauge couplings and any parameters you have deﬁned in your potential. c) In the usual standard model, the ratio of the masses of the Z and W bosons is M Z /M W = 1 / cos θ W , where θ W is the weak mixing angle (i.e. tan θ W = g 1 /g 2 ). In our alternative model, is there a value of the Higgs expectation value such that the ra-tio of masses satisﬁes this relation? State two measurements which can distinguish this spectrum from the conventional standard model ones. d) Construct all possible renormalizable Yukawa interactions in the non-standard model. Which fermions, if any, get a mass? 1...
