Observation of the radiative decays of $I^¥ (1 S)$ to $I ¨ _{c 1}$

P. Katrenko, I. Adachi, H. Aihara +166

We report the first observation of the radiative decay of the $I^¥ (1 S)$ into a charmonium state. The statistical significance of the observed signal of $I^¥ (1 S) \to I^^{3} I ¨ _{c 1}$ is 6.3…

Measurement of the branching ratios $I ¨ ^{'} \to e^{+} e^{-}$ , $I ¨ ^{'} \to J / I ¨ I ¨ I ¨ $ and $I ¨ ^{'} \to J / I ¨ I^\cdot$

M. Andreotti, S. Bagnasco, W. Baldini +46

We have measured several branching ratios for $I ¨ ^{'}$ decay using the data collected by FNAL E835 experiment during year 2000, obtaining ${\cal B}(Ï^\prime \to e^+ e^-) = 0.00…

Test of lepton-flavor universality in $B \to K^{*} ℓ^{+} ℓ^{-}$ decays at Belle

Belle Collaboration, S. Wehle, I. Adachi +179

We present a measurement of $R_{K^{*}}$ , the branching fraction ratio $B (B \to K^{*} I^¼^{+} I^¼^{-})$ / $B (B \to K^{*} e^{+} e^{-})$ , for both charged and neutral $B$ me…

Measurement of $B^{0} \to D_{s}^{-} K_{S}^{0} I ¨ ^{+}$ and $B^{+} \to D_{s}^{-} K^{+} K^{+}$ branching fractions

J. Wiechczynski, J. Stypula, A. Abdesselam +171

We report a measurement of the $B^{0}$ and $B^{+}$ meson decays to the $D_{s}^{-} K_{S}^{0} I ¨ ^{+}$ and $D_{s}^{-} K^{+} K^{+}$ final states, respectively, using $657 \times 1 0^{6} B B$ pairs co…

Study of Excited $I^_{c}$ States Decaying into $I^_{c}^{0}$ and $I^_{c}^{+}$ Baryons

Belle Collaboration, J. Yelton, I. Adachi +151

Using a data sample of 980 $fb^{- 1}$ of $e^{+} e^{-}$ annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we report the resu…

Measurement of the decay $B \to D ℓ I^½_{ℓ}$ in fully reconstructed events and determination of the Cabibbo-Kobayashi-Maskawa matrix element $∣ V_{c b} ∣$

R. Glattauer, C. Schwanda, A. Abdesselam +178

We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element $∣ V_{c b} ∣$ using the decay $B \to D ℓ I^½_{ℓ}$ ( $ℓ = e, I^¼$ ) based on 711 fb $^{- 1}$ of $…
