Abstract A brief overview of the anticipated heavy quark physics at HERA is given. The topics discussed include heavy quark photo- and leptoproduction cross sections at HERA calculated in the context of perturbative QCD, various mechanisms of J / ϕ -leptoproduction and their rates, determination of the gluon density of the proton using open and ...

Heavy quark expansion for heavy hadron lifetimes: completing the $$ 1/{m}_b^3 $$ corrections [PDF]
Journal of High Energy Physics, 2020 We complete the calculation of the contributions from the dimension six operators in the heavy quark expansion for the total lifetime of heavy hadrons. We give the leading order expressions for the Wilson coefficients of the Darwin term ρD and the spin ...

R(D∗), |Vcb|, and the Heavy Quark Symmetry relations between form factors [PDF]
Journal of High Energy Physics, 2017 Stringent relations between the B(∗) → D(∗) form factors exist in the heavy quark limit and the leading symmetry breaking corrections are known. We reconsider their uncertainty and role in the analysis of recent Belle data for B → D(∗)ℓν with model ...

Reports on Progress in Physics, 1986
The author discusses the physics of the hadrons containing charmed, bottom and top quarks. The emphasis is on the most recent experimental results from the e+e- storage rings in the 3-12 GeV range of centre-of-mass energy: SPEAR at SLAC, DORIS at DESY, and the Cornell Electron Storage Ring CESR.

Physics of heavy-quark production in quantum chromodynamics
Physical Review D, 1987For very heavy quark masses, QCD predicts that the inclusive hadronic production of heavy quarks is governed by quark and gluon hard-scattering subprocesses. On general grounds, one expects corrections of order \ensuremath{\mu}/${M}_{Q}$, where \ensuremath{\mu}\ensuremath{\sim}300 MeV and ${M}_{Q}$ is the heavy-quark mass. At the charm mass scale, such
