We discuss the motivations and perspectives for the studies of the mesons of the (bc) family at LHCb. The description of production and decays at LHC energies is given in details. The event yields, detection efficiencies, and background conditions for several B c decay modes at LHCb are estimated.

In the framework of three-point QCD sum rules, the form factors for the semileptonic decays of B + c → B s (B * s)l + ν l are calculated with account for the Coulomb-like α s /v-corrections in the heavy quarkonium. The generalized relations due to the spin symmetry of HQET/NRQCD for the form factors are derived at the recoil momentum close to zero. The… (More)

We consider general physical characteristics of doubly heavy baryons: the spectroscopy in the framework of potential approach and sum rules of QCD, mechanisms of production in various interactions on the basis of fragmentation model with account of preasymptotic corrections caused by higher twists over the transverse momentum of baryon, inclusive decays and… (More)

Semileptonic B c-meson decays in sum rules of QCD and NRQCD. Abstract The semileptonic B c-meson decays into the heavy quarkonia J/ψ(η c) and a pair of lep-tons are investigated in the framework of three-point sum rules of QCD and NRQCD. Calculations of analytical expressions for the spectral densities of QCD and NRQCD cor-relators with account for the… (More)

This Technical Design Report is dedicated to Tom Ypsilantis. Tom conceived the Ring Imaging Cherenkov detectors for particle identification in LHCb and he made an inestimable contribution to the LHCb RICH project. Tom would have wished to see these detectors in operation. He was totally dedicated to the project. He will be missed by the RICH group for his… (More)

In the framework of model motivated by perturbative calculations in QCD we estimate the differential and total cross sections for both the photoproduction of vector D *-mesons and their yield in deep inelastic scattering at the HERA collider. The offered model allows us to take into account higher twists over the transverse momentum of meson at p T ∼ m c… (More)

The cross-section for the double charmed baryon production at a B-factory is estimated on the basis of the perturbative QCD calculations for the cc-diquark production as well as of the quark-hadron duality.

We propose a modification of the mechanism of charmed quarks fragmentation into D mesons in hadronic collisions. It is shown that the distinction in valence quark distributions in the initial π ± and K ± mesons leads to different inclusive spectra of D and D s mesons produced in π ± and K ± beams.
