On Vud determination from neutron decay
نویسنده
چکیده
The recent results of the PIBETA experiment strongly suggest the presence of a non(V−A) anomalous interaction in the radiative pion decay. The same interaction should inevitably contribute to the neutron decay and in particular it should affect the Vud determination. This paper is dedicated to the prediction of the eventual discrepancy in Vud extracted from the super-allowed 0 + → 0 Fermi transitions and from the polarized neutron decay.

Letter of Intent for an Experiment at the Spallation Neutron Source Precise Measurement of the Neutron Beta Decay Parameters
We propose to perform a precise measurement of a, the electronneutrino correlation parameter, and b, the Fierz interference term in neutron beta decay, at the Fundamental Neutron Physics Beamline at the SNS, using a novel electric/magnetic field spectrometer and detector design. The experiment is aiming at the 10−3 accuracy level in a, and will provide an independent measurement of λ = GA/GV , ...
متن کاملIs the Unitarity of the quark-mixing-CKM-matrix violated in neutron β-decay?
This article is about the interplay between the Standard Model of elementary particle physics and neutron β-decay. Since the Fermi decay constant is known from muon decay, the Standard Model describes neutron β-decay with only two additional parameters. One parameter is the first entry |Vud| of the CKMmatrix. The other one is λ, the ratio of the vector coupling constant and the axial vector con...
متن کاملTHE EVALUATION OF Vud, EXPERIMENT AND THEORY
The value of the Vud matrix element of the Cabibbo-Kobayashi-Maskawa (CKM) matrix can be derived from nuclear superallowed beta decays, neutron decay, and pion beta decay. We survey current world data for all three. Today, the most precise value of Vud comes from the nuclear decays; however, the precision is limited not by experimental error but by the estimated uncertainty in theoretical corre...
متن کاملIsospin Breaking in Neutron β-decay and SU(3) Violation in Semi-leptonic Hyperon Decays
Present precision measurements of the neutron life time lead to a CKM matrix element |Vud| which is three standard deviations off the value inferred from heavy quark decays etc. We investigate the possibility whether isospin-breaking effects in the neutron-to-proton vector current transition matrix element 〈p|V + 0 |n〉 = 1 + δgV could eventually close this gap. For that we calculate in chiral p...
