Hard exclusive production of tensor mesons

We point out that hard exclusive production of tensor mesons f2(1270) with helicity λ=±2 is dominated by the gluon component in the meson wave function and can be used to determine gluon admixture in tensor mesons in a theoretically clean manner. We present a detailed analysis of the tensor meson distribution amplitudes and calculate the transition form factor γ+γ∗→f2(1270) for one real and one virtual photon.
