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 ratio 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 nonstandard model. Which fermions, if any, get a mass? 1...
