Exclusive B-meson Rare Decays and General Relations of Form Factors in Effective Field Theory of Heavy Quarks

M. Zhong, Y. L. Wu, W. Y. Wang

B meson rare decays ($B\to K(K^{\ast })l\bar{l}$ and $B\to K^{\ast }\gamma$) are analyzed in the framework of effective field theory of heavy quarks. The semileptonic and penguin type form factors…
