Heavy quark physics in the covariant quark model.
I give a short introduction to the covariant quark model and its applications to heavy quark physics. The special emphasis will be devoted to the semileptonic, rare and radiative decays of the $\Lambda_b$-baryon.

Lattice Results For Heavy Quark Physics [PDF]
The status of lattice calculations for heavy quark systems is reviewed, focussing on weak matrix elements for leptonic and semi-leptonic decays of heavy mesons. After an assessment of the main systematic errors, results for the decay constants $f_D$ and $f_B$, the $B$ parameter describing $B - \bar{B}$ mixing, the Isgur-Wise function and the ...

Aspects of Heavy Quark Physics
We discuss the use of two QCD based effective field theories in determining parameters of the standard model. Heavy Quark Effective theory provides a framework for studying the weak decays of the B meson. We calculate the B → Xclv decay rate to second nonvanishing order in the HQET expansion and compare the theoretical prediction to experimental data ...

Heavy-quark thresholds in Higgs-boson physics [PDF]
We perform a comprehensive study of the effects related to a heavy-quark threshold in the production and decay of a scalar or pseudoscalar Higgs particle. We study the QCD corrections to the decay mode into a quark-antiquark pair and also the mixing of a Higgs boson with quarkonium states, both below and above the open-flavor threshold, which can ...

QCD at the amplitude level: Fock state interference in heavy quark electroproduction
Quantum chromodynamics (QCD) rigorously predicts the existence of both nonperturbative intrinsic and perturbative extrinsic heavy quark contents of nucleons.

QCD light-cone distribution amplitudes of heavy mesons from boosted HQET
Light-cone distribution amplitudes (LCDAs) frequently arise in factorization theorems involving light and heavy mesons. The QCD LCDA for heavy mesons includes short-distance physics at energy scales of the heavy-quark mass.
