The Weak Charge of the Proton and New Physics
We address the physics implications of a precision determination of the weak charge of the proton, QW (p), from a parity violating elastic electron proton scattering experiment to be performed at the Jefferson Laboratory. We present the Standard Model (SM) expression for QW (p) including one-loop radiative corrections, and discuss in detail the theoretical uncertainties and missing higher order...
متن کاملNew Physics at the LHC: Strong vs Weak symmetry breaking
where Ψ is a collective index for the Standard Model (SM) fermions and i, j are generation indices. A remarkable property that has emerged, and that is most clearly exhibited by the Lagrangian L, is that while all the fundamental interactions among the particles are symmetric under a local SU(2)L×U(1)Y invariance, the observed mass spectrum is not. In other words, the electroweak symmetry is hi...

Spin Effects in the Weak Interaction
Modern experiments investigating the beta decay of the neutron and light nuclei are still provide important constraints on the theory of the weak interaction. Beta decay experiments are yielding more precise values for allowed and induced weak coupling constants and putting constraints on possible extensions to the standard electroweak model. Here we emphasize the implications of recent experim...
