QCD sum rules which have great success in reproducing hadronic properties are based on the Wilson's operator product expansion; in a way it makes use of the appropriate window of energy scale where both hadronic description and the quark-gluon description are valid. Special emphasis is put on ...
By combining potential models and QCD spectral sum rules (QSSR), we discuss the spectroscopy of the(bc¯)mesons and of the (bcq), (ccq) and (bbq) baryons (q≡dors), the decay constant and the (semi)leptonic decay modes of theBcmeson. For the masses, the best predictions come from...
By making suitable assumptions on theSU 3 transformation properties of the mass operator, we get a modified Gell-Mann-Okubo (GMO) mass formula, which, in general, depends on five parameters. In any sector, the number of parameters surviving in the mass formula (i.e. the pattern of symmetry...
It examines the relationship of such data to conventional models of hadron structure, the interpretation of sum-rules like those of Ellis and Jaffe and Gottfried, and finally the potential for refinement of our understanding of nuclear structure. 关键词: Theoretical or Mathematical, Experimental/ ...

These measurements will certainly help us to understand the production and decay properties of the Bc meson. Very recently, the LHCb Collaboration have firstly mea- sured the Bc+ → D0 K + decay mode with a statistical sig- nificance of 5.1σ using proton–proton collision data corre- ...
In this article, we review the current status ofB-mixing andb-hadron lifetimes both from experimental and theoretical points of view. Furthermore, we discuss the phenomenological potential of these observables for deepening our understanding of quantum chromodynamics (QCD) and for indirect searches for...
