aCORN: A New Measurement of the Electron- antineutrino Correlation Coefficient in Neutron Decay
The aCoRn collaboration plans to measure the electron-antineutrino correlation coefficient (“little a”) in neutron decay. “a” is the least well known of the neutron decay coefficients. It’s value, when combined with other neutron decay parameters, can be used to determine the weak vector and axial vector coupling constants and to test the validity and self-consistency of the Electroweak Standar...
متن کاملDetermination of the Electron-Antineutrino Angular Correlation Coefficient a0 in Unpolarized Neutron β-Decay
The coefficient a 0 has been derived from a measurement of the integral spectrum of recoil protons stored in a quasi-Penning trap with inhomogeneous magnetic field and adiabatic focusing onto an electro-static mirror of potential variable in 10 V steps between 0 V and 850 V. Correction for incomplete transfer of energy from transverse to longitudinal degrees of freedom, and the violation of the...
متن کاملA method for an improved measurement of the electron–antineutrino correlation in free neutron beta decay
The angular correlation between the beta electron and antineutrino in nuclear beta decay is characterized by the dimensionless parameter a. The value of a for free neutron decay, when combined with other neutron decay parameters, can be used to determine the weak vector and axial vector coupling constants gV and gA and test the validity and selfconsistency of the Electroweak Standard Model. Pre...

متن کاملAn experiment for the measurement of the bound-beta decay of the free neutron
The hyperfine-state population of hydrogen after the bound-beta decay of the neutron directly yields the neutrino left-handedness or a possible right-handed admixture and possible small scalar and tensor contributions to the weak force. Using the through-going beam tube of a high-flux reactor, a background free hydrogen rate of ca. 3 s can be obtained. The detection of the neutral hydrogen atom...
