effective hamiltonian of electroweak penguin for hadronic b quark decays

in this research we work with the effective hamiltonian and the quark model. we investigate the decay rates of matter-antimatter of quark. we describe the effective hamiltonian theory and apply this theory to the calculation of current-current ( ), qcd penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. the gluonic penguin structure of hadronic decays is studied through the wilson coefficients of the effective hamiltonian. we calculate the branching ratios of the tree-level, effective hamiltonian, effective hamiltonian including electroweak penguin, effective hamiltonian including magnetic dipole and the effective hamiltonian including electroweak penguin and magnetic dipole quark decays , , , . we show that, the electroweak penguin and magnetic dipole contributions in b quark decays are small and current-current operators are dominant.
