Phenomenological studies on neutral B-meson decays into $$J/\psi f_1$$ J / ψ f 1 and $$\eta _c f_1$$ η c f 1
Abstract The axial-vector mesons $$f_1(1285)$$ f 1 ( 1285 ) and $$f_1(1420)$$ f 1 ( 1420 ) are particularly viewed as the mixtures of flavor states $$f_n$$ f n and $$f_s$$ f s with mixing angle $$\varphi $$ φ . In order to determine this angle, we study the $$B_{d,s}^0\rightarrow J/\psi f_1(1285,142...
