The Effects Of Rho-omega Mixing In Radiative Vector Meson Decays

Description

The radiative &amp / #969 / &amp / #8594 / &amp / #960 / 0&amp / #960 / 0&amp / #947 / , &amp / #961 / &amp / #8594 / &amp / #960 / 0&amp / #960 / 0&amp / #947 / , &amp / #969 / &amp / #8594 / &amp / #960 / +&amp / #960 / &amp / #8722 / &amp / #947 / and &amp / #961 / &amp / #8594 / &amp / #960 / +&amp / #960 / &amp / #8722 / &amp / #947 / decays
are studied by adding the effect of vector meson mixing to the amplitude of
these decays. For the above decays we consider only &amp / #961 / &amp / #8722 / &amp / #969 / mixing. In addition
to the &amp / #961 / &amp / #8722 / &amp / #969 / mixing, we also analyse the contributions coming from different
intermediate states to examine the decay mechanism of these decays in a phenomenological
framework. For &amp / #969 / &amp / #8594 / &amp / #960 / 0&amp / #960 / 0&amp / #947 / decay, we consider the contributions
of the &amp / #961 / -meson and &amp / #963 / -meson intermediate states and of the kaon-loop, and for
the &amp / #961 / &amp / #8594 / &amp / #960 / 0&amp / #960 / 0&amp / #947 / decay we calculate the amplitude using the contributions of the
&amp / #969 / -meson and &amp / #963 / -meson intermediate states and pion-loop. Moreover, the radiative
&amp / #969 / &amp / #8594 / &amp / #960 / +&amp / #960 / &amp / #8722 / &amp / #947 / decay is studied by considering the contributions of &amp / #963 / -meson
and &amp / #961 / -meson intermediate states and the decay &amp / #961 / &amp / #8594 / &amp / #960 / +&amp / #960 / &amp / #8722 / &amp / #947 / is investigated by
taking into account the contributions of bremmsstrahlung, pion-loop and &amp / #963 / -
meson intermediate state amplitude. We also estimate the coupling constant
g&amp / #969 / &amp / #963 / &amp / #947 / utilizing the latest experimental value of the branching ratio &amp / #969 / &amp / #8594 / &amp / #960 / 0&amp / #960 / 0&amp / #947 / .
