Heavy-quark pair production in polarized photon-photon collisions at next-to-leading order: Fully integrated total cross sections

B. A. Kniehl, A. V. Kotikov, Z. V. Merebashvili +1

We consider the production of heavy-quark pairs in the collisions of polarized and unpolarized on-shell photons and present, in analytic form, the fully integrated total cross sect…

Heavy quark pair production in gluon fusion at next-to-next-to-leading $O (α_{s}^{4})$ order: One-loop squared contributions

B. Kniehl, J. G. Körner, Z. Merebashvili +1

We calculate the next-to-next-to-leading order $O (α_{s}^{4})$ one-loop squared corrections to the production of heavy-quark pairs in the gluon-gluon fusion process. Together wit…

Expansion of massive scalar one-loop integrals to O(ε^2)

J. G. Körner, Z. Merebashvili, M. Rogal

We report on the results of an ongoing calculation of massive scalar one-loop one-, two-, three- and four-point functions needed in the NNLO calculation of heavy hadron production.

Analytically integrated results for heavy fermion production in two-photon collisions and a high precision $α_{s}$ determination

B. Kamal, Z. Merebashvili

The cross section for massive fermion production in two-photon collisions was examined at next-to-leading order in QCD/QED for general photon helicity. The delta function (virtual+…
