resource letters A1150L Sum rules A1235C General properties of quantum chromodynamics (dynamics, confinement, etc.)We review the theoretical basis and the applications to hadronic physics of the QCD sum rules invented by Shifman, Vainshtein and Zakharov....
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...
To demonstrate the accuracy of the approximation we evaluate several static properties like energy, mean square radius, axial-vector constant and delta-nucleon mass splitting using both self-consistent and reference profiles. The agreement is found to be very well in the physically relevant mass ...
We, therefore, reduce our lattice size to enable the calculation on the quantum machine and compute the properties of the meson for N = 2. By applying the strategies discussed in the baryon case we can reduce the number of necessary qubits from four to three. In Fig. 4 we report ...
Direct probe of the quark-gluon content of hadrons with hadron beams started with low-energy facilities, such as J/ψproduction at AGS, in the 70’s.However, experiments at these facilities are barely explainable with perturbative QCD, and the statistical accuracy of the data does not allow ...
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...

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- ...
