Strategy for detecting b polarization effects.
We suggest a strategy for detecting {ital b} polarization effects in {ital e}{sup +}{ital e}{sup {minus}} annihilation on {ital Z} resonance. Using two types of inclusive leptonic samples with different {Lambda}{sub {ital b}} fractions in {ital Z}{r_arrow}{ital b{bar b}} events, the {ital b} polarization effects may be detected without large uncertainties of {ital b} fragmentation and the {Lambda}{sub {ital b}} decay model.
The weak-magnetic moment of heavy quarks
Abstract With initial and final particles on-shell, the anomalous weak-magnetic dipole moments of b and c quarks are electroweak gauge invariant quantities of the effective couplings Zb b and Zc c , respectively, and good candidates to test the Standard Model and/or new physics. Here we present a complete computation of these quantities within the Standard Model. We show that decoupling properties with respect to heavy particles do take place in the weak magnetic moment. The obtained values, a b ( M Z 2 ) = (2.98 − 1.56 i ) × 10 −4 and a c ( M Z 2 ) = (−2.80 + 1.09 i ) × 10 −5 are dominated by one-gluon exchange diagrams. The electroweak corrections are less than 1% of the total magnitude.
