Radiative Φ→σγ Vertex in QCD Sum Rules and Phenomenological Approach

摘要

We estimate the coupling constant g_(Φσγ) by using the three-point correlation function and we also investigate this coupling constant by studying the effective lagrangians. Here we consider the effect the Φ-ω mixing effect to the calculation. Besides, a comparison of our predictions with the theoretical results existing in literature is presented.
