### Description

Lepton-nucleon scattering experiments are performed to investigate the (spin-)structure of nucleons. The theoretical framework for the interpretation of such measurements is perturbative QCD (pQCD). In this contribution we present the measurement of the cross section for the quasi-real photoproduction of charged hadrons with high transverse momenta in muon-deuteron scattering at COMPASS ($\sqrt{s} = 17.4$\,GeV). Furthermore, the dependence of the cross section on pseudo-rapidity and the hadron charge is discussed. The results are compared to recent next-to-leading (NLO) pQCD calculations to evaluate the applicability of pQCD to this process at COMPASS energies.
