Taking into account the constraints on non-standard interactions (NSIs) of neutrinos and light gauge boson , we compute their contributions to the branching ratio with V denoting the vector mesons ρ, ω or ϕ. Our numerical results show that the value of is larger than the corresponding SM prediction at least by an order of magnitude. The contributions of leptoquarks (LQs) to the invisible decay are also discussed.
