any loop involving the Higgs which might give a stronger bound (I’m not asking you to do the loop – just draw it)? What would you measure to compare against this theory prediction? 4. * In supersymmetry, each fermion has a scalar partner, and each gauge boson has a Fermionic partner. For example, the partner of the muon is the smuon ( μ ˜ ) and the partner of the photon is the photino ( A ˜ ). The Lagrangian gets additional terms L SUSY = L SM + 1 2 μ ˜( square + m μ ˜ 2 ) μ ˜ + A ˜ ( + m A ˜ ) A ˜ + ˜ μA ˜ (2) Here, the size of the Yukawa coupling is fixed to the muon’s charge e 0.3 by gauge invariance and supersymmetry. Since the smuon is charged, it may have a very large effect on the g -factor of the muon. a) Assuming m A ˜ = m μ , what bound on m μ ˜ do you get from g - 2? b) For other reasons, we expect m A ˜ m μ ˜ M SUSY . What bound on M SUSY do you get from g - 2 ? 1
