Systematics of heavy quarkonia from Regge trajectories on and planes
In this paper we show that heavy quarckonium states, similar to light mesons,
form Regge trajectories in and planes and the slope of
these trajectories is independent on the quantum numbers of the mesons. This
fact can be useful for the prediction of the masses of heavy quarkonia and the
determination of the quantum numbers of the newly discovered states.Comment: 10 pages, 2 figures, 2 tables; some refrences are added, comparison

Parallelization of sequential programs: distribution of arrays among processors and structurization of communications
Data distribution functions are introduced. They are matced with scheduling functions. The processors and iterations are determined that use an array element at its fixed position in a statement. This makes it possible to obtain the initial data distribution and also information on the data volume for every processor and on the structure of required communication
QCD one-loop correction to Higgs boson decay into quarkonium-pair
Rare decays of the Higgs boson into quarkonia-pairs are studied within the
framework of NRQCD approach. The main decay mechanisms and their interference
are studied in detail. One-loop corrections to the widths of these decays are
taken into account for the first time.Comment: Minor changes for the text. Has been accepted by Phys. Rev.
Prospects for the Bc Studies at LHCb
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.Comment: 20 pages, 5 eps-figure
