1. On some implications of the BaBar data on the γ ⁎ η ′ transition form factor / Kroll, P. ; Passek-Kumerički, K.
At leading-twist accuracy the form factors for the transitions from a virtual photon to the η or η′ can be expanded into a power series of the variable ω , being related to the difference of the two photon virtualities. [...]

2. Probing axial quark generalized parton distributions through exclusive photoproduction of a γπ ± pair with a large invariant mass / Duplančić, G. ; Passek-Kumerički, K. ; Pire, B. ; Szymanowski, L. ; et al
Exclusive photoproduction of a γπ ± pair in the kinematics where the pair has a large invariant mass and the final nucleon has a small transverse momentum is described in the collinear factorization framework. [...]

4. Next-to-leading order corrections to deeply virtual production of pseudoscalar mesons / Duplančić, G. ; Müller, D. ; Passek-Kumerički, K.
We complete the perturbative next-to-leading order corrections to the hard scattering amplitudes of deeply virtual meson leptoproduction processes at leading twist-two level by presenting the results for the production of flavor singlet pseudoscalar mesons. [...]

5. Towards a fitting procedure to deeply virtual meson production – the next-to-leading order case / Müller, D. ; Lautenschlager, T. ; Passek-Kumerički, K. ; Schäfer, A.
Based on the collinear factorization approach, we present a comprehensive perturbative next-to-leading (NLO) analysis of deeply virtual meson production (DVMP). [...]
