Using Bs(t) -> phi K_s to measure Sin 2 beta
Alakabha Datta, C. S. Kim, David London
In this talk we show that, unlike other pure penguin processes, the decay $\bs(t)\toϕ\ks$ is dominated by a single amplitude, that of the internal -quark. Thus, the ind…
Measurement of the Lifetime Difference of Mesons: Possible and Worthwhile?
A. S. Dighe, T. Hurth, C. S. Kim +1
We estimate the decay width difference in the system including contributions and next-to-leading order QCD corrections, and find it to be around 0.3%…
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^{(*…
Difficulties in Obtaining Weak Phases from Penguin Decays
Alakabha Datta, C. S. Kim, David London
We re-examine a recent proposal for obtaining βusing the measurements of the b -> d penguin decays B_d(t) -> K^0 \kbar and B_s(t) -> ϕK_S, along with a theoretical assumption. We s…
Determination of the CP Phase with Possibility of New Physics
C. S. Kim, Sechul Oh
We propose a new method to extract the CP violating weak phase in the CKM paradigm of the Standard Model, using and …
New Physics Working Group Summary of LCWS2000 at FNAL
C. S. Kim
Here I summarize P5-WG (New/Alternative Physics Working Group) of LCWS2000@FNAL, held on Oct 24-28, 2000. There were 13 talks altogether, 7 talks on collider signals from new parti…
