Systematic Investigation of Possibilities for New Physics Effects in b --> s Penguin Processes

C. S. Kim, Y. J. Kwon, Jake Lee +1

Although recent experimental results in b-->s penguin process seem to be roughly consistent with the standard model predictions, there may be still large possibilities of new physi…

Implications of the first observation of $B \to K_{1} γ$

Y. J. Kwon, Jong-Phil Lee

Implications of the recent new measurements of $B \to K_{1} γ$ by Belle are examined. It is shown that the new branching ratio $\calB(B\to K_1(1270)γ)$ requires very large form factor…

Test of Factorization Hypothesis from Exclusive Non-leptonic B decays

C. S. Kim, Y. Kwon, Jake Lee +1

We investigate the possibility of testing factorization hypothesis in non-leptonic exclusive decays of B-meson. In particular, we considered the non factorizable \bar{B^0} -> D^{(*…

Measurement of |V_{ub}/V_{cb}| (and |V_{ub}|) in Exclusive Nonleptonic Decays, \bar{B}^0 --> D_s^{()-}(π^+,ρ^+) and \bar{B}^0 --> D_s^{()-}D^{(*)+}

C. S. Kim, Y. Kwon, Jake Lee +1

We have studied extracting $|\vub/\vcb|$ by calculating the ratios $B (B ˉ^{0} \to D_{s}^{(*) -} (π^{+}, ρ^{+})) / B (B ˉ^{0} \to D_{s}^{(*) -} D^{(*) +})$ including penguin effects…

A Measurement of $B (D_{s} \to ϕ l^{+} ν) / c a l B (D_{s} \to ϕ π^{+})$

The CLEO Collaboration

Using the CLEO~II detector at CESR, we have measured the ratio of branching fractions $B (D_{s}^{+} \to ϕ e^{+} ν) / B (D_{s}^{+} \to ϕ π^{+}) = 0.54 \pm 0.05 \pm 0.04$ . We use this meas…
