FIRST DIRECT MEASUREMENT OF THE PARITY-VIOLATING COUPLING OF THE Z TO THE s-QUARK∗
We have made the first direct measurement of the parity-violating coupling of the Z boson to the strange quark, As, using ∼550,000 ee → Z0→hadrons events produced with a polarized electron beam and recorded by the SLD experiment. Z0→ ss̄ events were tagged by the absence of B or D hadrons and the presence in each hemisphere of a high-momentum K or K s . From the polar angle distributions of the ...

متن کاملFirst direct measurement of the parity-violating coupling of the Z0 to the s quark
We present the first direct measurement of A(s), the parity-violating coupling of the Z0 boson to the strange quark, using approximately 550 000 e(+)e(-)-->Z0-->hadrons events recorded by the SLC Large Detector with a polarized e(-) beam. We tagged Z0-->s&smacr; events by the absence of B or D hadrons and the presence in each hemisphere of a high momentum K+/- or K(0)(s). Fitting the polar angl...
