Abstract

We predict the V\ensuremath→P\ensuremathγ decay widths and the V\ensuremath→P\ensuremathγ^* transition form factors, where V=(\ensuremathρ,\ensuremathω,K^*,\ensuremathφ) and P=(\ensuremathπ,K,\ensuremathη,\ensuremathη^\ensuremath'), using spin-improved holographic light-front wave functions for the mesons. We find excellent agreement with the available data for both the decay widths and the timelike transition form factors extracted from the leptonic conversion decays V\ensuremath→Pl⁺l^\ensuremath-.
