Description

The extraction of time-like gravitational formfactors from exclusive meson pair production is discussed. The special attention is payed to structures which should cancel between quarks and gluons but may be non-zero for quarks. In particular, dipole term may be associated with shear viscosity. Its studies in exotic hybrid mesons production is addressed. The smallness of the respective GDA may be an analog of smallness of shear viscosity in holographic approach,
