Abstract:

We present the first measurement of the D*(+) width using 9/fb of e(+)e(-) data collected near the Upsilon(4S) resonance by the CLEO II.V detector. Our method uses advanced tracking techniques and a reconstruction method that takes advantage of the small vertical size of the Cornell Electron-positron Storage Ring beam spot to measure the energy release distribution from the D*(+)-->D(0)pi(+) decay. We find gamma(D*(+)) = 96+/-4 (stat)+/-22 (syst) keV. We also measure the energy release in the decay and compute Delta m identical with m(D*(+))-m(D(0)) = 145.412+/-0.002 (stat)+/-0.012 (syst) MeV/c(2).

Hadronic mass moments in inclusive semileptonic B meson decays

Physical Review Letters 87:25 (2001)

Abstract:

The first and second moments of the hadronic mass-squared distribution in the B meson semileptonic decay to charm, B → X c ℓ ν, were measured. The measurement of and the heavy quark effective theory expression for this moment were used, in conjunction with similar information on the first moment of the photon energy spectrum in B → s λ. As a result, λ and ∧̄ were determined.

Abstract:

We have measured the first and second moments of the hadronic mass-squared distribution in B-->X(c)l nu, for P(lepton)>1.5 GeV/c. We find = 0.251+/-0.066 GeV(2), <(M(2)(X)-)(2)> = 0.576+/-0.170 GeV(4), where M macro(D) is the spin-averaged D meson mass. From that first moment and the first moment of the photon energy spectrum in b-->s gamma, we find the heavy quark effective theory parameter lambda(1) (in the modified minimal subtraction renormalization scheme, to order 1/M(3)(B) and beta(0)alpha(2)(s)) to be -0.24+/-0.11 GeV(2). Using these first moments and the B semileptonic width, and assuming parton-hadron duality, we obtain absolute value of V(cb) = 0.0404+/-0.0013.

Abstract:

We present a search for the "wrong-sign" decay D0 → Κ+π-π+π- using 9 fb-1 of e+e- collisions on and just below the Y(4S) resonance. This decay can occur either through a doubly Cabibbo-suppressed process or through mixing to a D̄0 followed by a Cabibbo-favored process. Our result for the time-integrated wrong-sign rate relative to the decay D0 → Κ-π+π-π+ is (0.0041-0.0011+0.0012(stat)±0.0004(syst))×(1.07 ±0.10)(phase space), which has a statistical significance of 3.9 standard deviations. ©2001 The American Physical Society.
