The weak structure of the nucleon from muon capture on 3He

Abstract

I use a microscopic calculation of the weak capture process 3He(μ^{-},ν_μ)3H, to extract and constrain the weak form factors of the nucleon, particularly the induced pseudo-scalar, and the second-class currents. The induced pseudo-scalar form-factor is found to agree with the prediction of chiral perturbation theory. The constraint found on the conservation of vector current (CVC) hypothesis is the tightest to date.
