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 Bc decay modes at LHCb are estimated.

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 three-point QCD sum rules, the form factors for the semileptonic decays of B c → Bs(B∗ s )lνl are calculated with account for the Coulomb-like αs/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 nonleptonic… (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 ccdiquark production as well as of the quark-hadron duality.

On the basis of the exact formulas of QCD perturbation theory and parton model the hadronic production cross-sections for Bc(Bc )-mesons (1S0, 1 S1, 2 S0, 2 S1states) are calculated. The method used is the direct calculation of appropriate amplitudes with the help of a FORTRAN program and subsequent Monte-Carlo integration over the phase space and… (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)

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 pT ∼ mc and… (More)

A possibility to accelerate a high intensity polarized proton beam up to 70 GeV at the IHEP accelerator, extract it from the main ring and deliver to several experimental setups is being studied now. We propose to study a wealth of singleand double-spin observables in various reactions using longitudinally and transverserly polarized proton beams at U70.… (More)
