Single pseudoscalar and vector mesons hard semi-inclusive photo-production γhM X via higher twist (HT) mechanism is calculated using the QCD running coupling constant method. The structure of infrared renormalon singularities of the HT subprocess cross section and the Borei sum for it are found. The problem of normalization of HT process cross section in terms of the meson elm form factor is discussed.
