Strongly interacting (QCD) matter

At present, production, properties, and decays of exotic multiquark hadrons --- tetra- and pentaquarks are intensively studied both experimentally and theoretically.
Based on the $SU(3)_F$ flavor symmetry, there is a large number of such states which differ by their light quark content. Having already a 20-years' history, quite a few exotic hadrons are found experimentally despite predicted...

19. Production of bound states of quarks and leptons in rare Higgs boson decays

Strongly interacting (QCD) matter

The rare decay process of the Higgs boson into a pair of J/Ψ and ϒ particles is studied within the perturbative Standard Model and the relativistic quark model. We study also the processes of single and paired production of lepton bound states (positronium, dimuonium, ditauonium) within the framework of the relativistic approach we are developing [1-5]. The relativistic corrections connected...

14. Gravitational formfactors, equivalence principle and shear viscosity

Oleg Teryaev (JINR)

QCD (lattice, (non) perturbative, effective models)

Gravitational formfactors describe the (angular) momentum distribution in hadrons as well as their coupling to gravity. The equivalence principle may be extended to be valid separately for quarks and gluons. The small violation of such an extension may be related to the analog of shear viscosity contribution and be a counterpart of its smallness.

7. Shear viscosity and parton distributions

Oleg Teryaev (JINR)

Strongly interacting (QCD) matter

The shear-like contributions to energy-momentum tensors appearing in the definitions of hadronic matrix elements are considered. Their extraction from sum rule for various parton distributions is analyzed. The counterparts of the viscosity smallness manifested in holographic QCD are discussed.
