Sharpening low-energy, standard-model tests via correlation coefficients in neutron beta decay.
The correlation coefficients a, A, and B in neutron beta decay are proportional to the ratio of the axial-vector-to-vector weak coupling constants, gA/gV, to leading recoil order. With the advent of the next generation of neutron-decay experiments, the recoil-order corrections to these expressions become experimentally accessible, admitting a plurality of standard model (SM) tests. The measurem...
متن کاملLow Energy Tests of the Standard Model from β-Decay and Muon Capture
Two recent low energy precision experiments are considered, in order to illustrate how limits set by these measurements for couplings beyond the Standard Model are complementary to high energy constraints.

متن کاملTests of physics beyond the Standard Model with future low energy neutrino experiments
Neutrino-electron scattering can be used to probe neutrino electromagnetic properties at low-threshold underground detectors with good recoil electron energy resolution. We study the sensitivity of Helium detector experiments, such as HELLAZ, for artificial anti-neutrino sources. We show that, for a Sr − Y source, one expects a sensitivity to the neutrino magnetic moment at the level of μν = 2 ...
متن کاملLow Energy Tests of the Standard Model with Spin Degrees of Freedom
After briefly reviewing the status of the standard model, I will focus mainly on polarized electron scattering and other tests of the weak neutral current. I will also address other low energy tests in which polarization degrees of freedom play a crucial role, including precision muon physics and searches for electric dipole moments.
متن کاملPrecise Standard Model tests
I summarize the precision tests of the Standard Model in kaon physics which have been reported at this conference.
