Transverse lepton polarization in polarized W decays.
Calculations of transverse polarization of leptons in the decay W → lν with polarized W ’s are presented. Planned accelerators will produce enough W ’s for observation of the Standard Model contributions to this polarization. One loop corrections to the polarization are given; these are too small to be seen at presently available W sources. The exchange of Majorons will contribute to these pola...
متن کاملSearch for Exotic Couplings in Neutron Decay: A Measurement of the Transverse Polarization of Electrons
First results are presented from an experiment that aims at the simultaneous determination of both transversal polarization components of electrons emitted in the decay of free neutrons – two observables that have never before been addressed experimentally. They reveal first-order sensitivity to real and imaginary parts of the exotic scalar and tensor interactions.
متن کاملMeasurement of the transverse polarization of electrons emitted in free-neutron decay.
Both components of the transverse polarization of electrons (sigmaT1, sigmaT2) emitted in the beta-decay of polarized, free neutrons have been measured. The T-odd, P-odd correlation coefficient quantifying sigmaT2, perpendicular to the neutron polarization and electron momentum, was found to be R=0.008+/-0.015+/-0.005. This value is consistent with time reversal invariance and significantly imp...
متن کاملMeasurement of T-violating transverse muon polarization in K → π0μ+ν decay at J-PARC
We have proposed a new experiment to search for time reversal invariance violation by measuring the transverse muon polarization (PT ) in K+ → π0μ+ν decay at J-PARC. The physics potential in terms of the discovery of new physics along with the power to constrain exotic models is shown to be competitive with other experiments being planned or prepared. The detector system will be an upgraded ver...
متن کاملMeasurement of the transverse polarization of electrons emitted in neutron decay: A search for weak exotic couplings
First results are presented from an experiment that aims at the simultaneous determination of both transversal polarization components of electrons emitted in the decay of free neutrons—two observables that have never before been addressed experimentally. A non-zero value of the R correlation coefficient, due to the e polarization component perpendicular to the plane spanned by the spin of the ...
