Measurement of the polarization in the decays Bd-->J/ psi K*0 and Bs-->J/ psi phi. Academic Article uri icon

abstract

  • This Letter reports on measurements of the longitudinal polarization fractions in the decays BdJ/ K*0 and BsJ/ using data collected with the Collider Detector at Fermilab. Bd mesons are reconstructed through the decay chain BdJ/ K*0, J/+-, K*0K+-. A sample of 6510 Bd events is used to obtain a longitudinal polarization fraction of L/=0.650.10(stat)0.04(syst). Bs mesons are reconstructed through the decay chain BsJ/ , J/+-, K+K-. A sample of 195 Bs events is used to obtain the result L/=0.560.21(stat)-0.04+0. 02(syst). 1995 The American Physical Society.
