Abstract

We perform a model-independent analysis of the data on branching ratios and CP asymmetries of BϕKB\to\phi K and Bη()K()B\to\eta^{(')} K^{(*)} modes. The present data is encouraging to look for indirect evidences of physics beyond the Standard Model. We investigate the parameter spaces for different possible Lorentz structures of the new physics four-Fermi interaction. It is shown that if one takes the data at 1σ1\sigma confidence level, only one particular Lorentz structure is allowed. Possible consequences for the BsB_s system are also discussed.
