1. Precision measurement of the $��$-asymmetry in spin-polarized $^{37}\mathrm{K}$ decay

Abstract

Using TRIUMF's neutral atom trap, TRINAT, for nuclear $��$ decay, we have measured the $��$ asymmetry with respect to the initial nuclear spin in $^{37}\mathrm{K}$ to be $A_��=-0.5707(13)_\mathrm{syst}(13)_\mathrm{stat}(5)_\mathrm{pol}$, a 0.3% measurement. This is the best relative accuracy of any $��$-asymmetry measurement in a nucleus or the neutron, and is in agreement with the standard model prediction $-0.5706(7)$. We compare constraints on physics beyond the standard model with other $��$-decay measurements, and improve the value of $V_\mathrm{ud}$ measured in this mirror nucleus by a factor of 4.

3. The contribution of $��^* \to ����$ to measured $��$ polarization

Abstract

Calculations of the polarization of $��$ and $\bar��$ particles after fragmentation of a polarized quark produced in processes like $Z$-decay and deep inelastic polarized lepton scattering must include $��$ and $\bar��$ produced as decay products of $��^0$ and $��^*$ as well as those produced directly. These decay contributions are significant and not feasibly included in theoretical calculations based on QCD without additional input from other experimental data. Furthermore these contributions depend on the spin structure of the $��^0$ or $��^*$ and are not directly related to the structure function of the $��$, 6 pages, 1 figure

4. Expected Polarization of $��$ particles produced in deep inelastic polarized lepton scattering

Abstract

We calculate the polarization of Lambda and Anti-Lambda particles produced in deep inelastic polarized lepton scattering. We use two models: the naive quark model and a model in which SU(3)$_F$ symmetry is used to deduce the spin structure of SU(3) octet hyperons from that of the proton. We perform the calculations for Lambda and Anti-Lambda produced directly or as decay products of $��^0$ and $��^*$., 12 pages, 1 figure

Abstract

We report results of the first measurements of Λ and Λ̄ polarization produced in deep inelastic polarized muon scattering on the nucleon. The results are consistent with an expected trend towards positive polarization with increasing cursive Greek chiF. The polarizations of Λ and Λ̄ appear to have opposite signs. A large negative polarization for Λ at low positive cursive Greek chiF is observed and is not explained by existing models. A possible interpretation is presented.
