B-decays at Large $tan β$ as a Probe of SUSY Breaking

Seungwon Baek, P. Ko, Wan Young Song

We consider $B_{s} \to μ^{+} μ^{-}$ and the muon $(g - 2)_{μ}$ in various SUSY breaking mediation mechanisms. If the decay $B_{s} \to μ^{+} μ^{-}$ is observed at Tevatron Run II with a branching r…

Contribution of $b \to s g g$ through the QCD anomaly in exclusive decays $B \to (η^{'}, η) (K, K^{*})$

P. Ko

The charm content in $η^{'}$ is estimated using the QCD U(1) axial anomaly applied to $b \to s g g \to η^{'} s$ . We find $f_{η^{'}}^{(c)} \approx - 3.1$ MeV for $m_{c} = 1.3$ GeV. Our estimate…

Possible New Physics Signals in b -> s gamma and b -> s l^+ l^-

Yeong Gyun Kim, P. Ko, Jae Sik Lee

We consider possible new physics contributions to b\to s l^+ l^- assuming the new physics modifies (chromo)magnetic and electric form factors in b\to s γ^* and b\to s g with the sa…

Recent Developments In Heavy Quarkonium Physics

Pyungwon Ko

Recent developments in heavy quarknoium physics are reviewed in brief, including (i) nonrelativistic QCD(NRQCD), (ii) the importance of color-octet $(Q Q ˉ)$ components in the d…
