WR effects on CP angles determination at a B factory

The right-handed charged current gauge boson WR can affect significantly on the determination of the CP violation angles to be measured at B factories if the right-handed current quark mixing matrix VR is taken to a specific form to satisfy the bounds by neutral K meson system. The WR contribution can be sizable in B0-B0 mixing and tree level b quark decay. The deviation of the CP angles in unitarity triangle from the standard model values can be as large as −32° ∼ +19° for f3 (γ), and 66° ∼ 115° for f1 (β) and f2 (α) for mt = 175 GeV.
