We predict the charm and bottom quark nuclear modification factors using weakly coupled pQCD and strongly coupled AdS/CFT drag methods. The log(pT/M_Q)/pT dependence of pQCD loss and the momentum independence of drag loss lead to different…

We present studies from the LHCb experiment of decays of the type H_b to H_c X, where H_b represents a beauty hadron (B+, B0 or Lambda_b) and H_c a charmed hadron (D0, D(*)+, Ds or Lambda_c). Such decays are important for the determination…
We study baryon resonances with heavy flavor in a molecular approach, thus as dynamically generated by meson-baryon scattering. This is accomplished by using a unitary coupled-channel model taking, as bare interaction, the extension to four…
We study the medium modifications of baryon properties in nuclear many-body systems, especially in $\Lambda$ hypernuclei. The nucleon and the $\Lambda$ hyperon are described in the Friedberg-Lee model as nontopological solitons which…

We consider heavy mesons with charm and bottom in nuclear medium. We construct the effective Lagrangian with axial-vector coupling including 1/M-corrections for the heavy meson mass $M$ by following the velocity-rearrangement invariance. As…
The leading particle effect in charm hadroproduction is an enhancement of the cross section for a charmed hadron D in the forward direction of the beam when the beam hadron has a valence parton in common with the D. The large D+/D-…

Brueckner theory is used to investigate the in-medium properties of a $\Lambda$-hyperon in nuclear and neutron matter, based on hyperon-nucleon interactions derived within SU(3) chiral effective field theory (EFT). It is shown that the…

Leading charm hadrons produced in hadron-nucleus interactions cannot be adequately described within the parton fusion model. Recent results on charm baryon production in $\Sigma^- A$ interactions at 330 GeV with the WA89 detector disagree…
