| Abstract: | The high-twist contribution to large-transversemomentum lepton pair production in pion-hadron collisions is investigated. In calculations, various pion model wave functions are used. The high-twist contribution is shown to depend on the choice of wave functions and to exceed the leading one by an order of magnitude in the phase space boundary. |
