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.
Collective effects are reviewed for collisions of various systems – from proton-proton to heavy ion – in wide energy range. Collectivity is one of the crucially important and most essential fea-tures in reactions with subatomic particles due to strong interaction. As consequence, a study of collective behavior in multiparticle production processes provides one of the most sensitive and...
Discussion leader Roman Zhokhov (IZMIRAN, Troitsk)
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.
