Radiative Neutron β-Decay in Effective Field Theory
نویسندگان
چکیده
We consider radiative β-decay of the neutron in heavy baryon chiral perturbation theory. Nucleon-structure effects not encoded in the weak coupling constants gA and gV are determined at next-to-leading order in the chiral expansion, and enter at the [Formula: see text]-level, making a sensitive test of the Dirac structure of the weak currents possible.

Radiative Corrections for Neutron Decay and Search for New Physics
The expected increased accuracy of neutron β-decay experiments at the new Spallation Neutron Source could result in more stringent tests of the Standard Model. For an unambiguous search for new physics in neutron decay experiments and for a precise determination of fundamental constants, it is necessarily to understand and evaluate all corrections for neutron decay with higher accuracy than the...

Radiative corrections to the neutron β−decay within the Standard Model. Abstract Starting with the basic Lagrangian of the Standard Model, the radiative corrections to the neutron β−decay are acquired. The electroweak interactions are consistently taken into consideration amenably to the Weinberg-Salam theory. The effect of the strong quark-quark interactions on the neutron β−decay is parameter...
متن کاملRadiative Β Decay of the Free Neutron Physical
The theory of quantum electrodynamics predicts that the β decay of the neutron into a proton, electron, and antineutrino is accompanied by a continuous spectrum of emitted photons described as inner bremsstrahlung. While this phenomenon has been observed in nuclear β decay and electron-capture decay for many years, it has only been recently observed in free-neutron decay. We present a detailed ...
متن کاملStandard Model Treatment of the Radiative Corrections to Neutron β-Decay
Starting with the Standard Model electroweak Lagrangian, the radiative corrections to neutron β-decay are obtained. Nucleon compositeness is considered by appropriate parameterization of the nucleon weak transition current and electromagnetic form factors.
متن کاملRadiative Corrections to Low-Energy Neutrino-Deuteron Reactions Revisited
The one-loop QED and electroweak radiative corrections to neutrino-deuteron scattering induced by the neutral current are reexamined, paying a particular attention to the constant term which has never been treated properly in literature. This problem is closely related to the definition of the axial-vector coupling constant gA and requires thorough calculations of the constant terms in the char...
