Lepton asymmetry measurements in B̄→D*l-ν̄l and implications for V-A and the form factors
We present a measurement of the lepton decay asymmetry Afb in the reaction B¯→D*l−ν¯l using data collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR). The value of Afb confirms that the chirality of the weak interaction is predominantly left-handed in b→c transitions as ex...
