Abstract
We present a quenched lattice calculation of f(V)(perpendicular to)/f(V), the coupling of vector mesons to the tensor current normalized by the vector meson decay constant. The chirally improved lattice Dirac operator, which allows us to reach small quark masses, is used. We put emphasis on analyzing the quark mass dependence of f(V)(perpendicular to)/f(V) and find only a rather weak dependence. ...
Abstract
We present a quenched lattice calculation of f(V)(perpendicular to)/f(V), the coupling of vector mesons to the tensor current normalized by the vector meson decay constant. The chirally improved lattice Dirac operator, which allows us to reach small quark masses, is used. We put emphasis on analyzing the quark mass dependence of f(V)(perpendicular to)/f(V) and find only a rather weak dependence. Our results at the rho and phi masses agree well with QCD sum rule calculations and those from previous lattice studies.
