1. Coordinate space calculation of two- and three-loop sunrise-type diagrams, elliptic functions and truncated Bessel integral identities / Groote, S. ; Körner, J.G.
We integrate three-loop sunrise-type vacuum diagrams in D0=4 dimensions with four different masses using configuration space techniques. [...]

2. Resolving the SELEX–LHCb double-charm baryon conflict: the impact of intrinsic heavy-quark hadroproduction and supersymmetric light-front holographic QCD / Brodsky, S. J. ; Groote, S. ; Koshkarev, S.
In this paper we show that the intrinsic heavy-quark QCD mechanism for the hadroproduction of heavy hadrons at large xF can resolve the apparent conflict between measurements of double-charm baryons by the SELEX fixed-target experiment and the LHCb experiment at the LHC collider. [...]

3. NNLO QCD corrections to the polarized top quark decay t()Xb+W+ / Czarnecki, A. ; Groote, S. ; Körner, J. G. ; Piclum, J. H.
We compute the next-to-next-to-leading order (NNLO) QCD corrections to the decay t()Xb+W+ of a polarized top quark. [...]

4. T-odd correlations in polarized top quark decays in the sequential decay t()Xb+W+(++ν) and in the quasi-three-body decay t()Xb+++ν / Fischer, M. ; Groote, S. ; Körner, J. G.
We identify the T-odd structure functions that appear in the description of polarized top quark decays in the sequential decay t()Xb+W+(++ν) (two structure functions) and the quasi-three-body decay t()Xb+++ν (one structure function). [...]

5. Production of doubly charmed baryons nearly at rest / Groote, Stefan ; Koshkarev, Sergey
We investigate the production cross sections, momentum distributions and rapidity distributions for doubly charmed baryons which according to the intrinsic heavy quark mechanism are produced nearly at rest. [...]

6. Double quarkonium production at high Feynman- x / Koshkarev, Sergey ; Groote, Stefan
In this paper we give estimates for the proton–proton cross sections into pairs of quarkonium states J/ψ , ψ(2S) , ϒ(1S) and ϒ(2S) at the scheduled AFTER@LHC energy of 115 GeV. [...]
