[en] We study the form factors of the quark tensor currents in the pion at large squared momentum transfer Q2. It turns out that certain form factors can be evaluated using collinear factorization, whereas others receive important contributions from the end-point regions of the longitudinal quark momenta in the pion. We derive simple analytic expressions for the dominant terms at high Q2 and illustrate them numerically. (orig.)
