Title: "Gravitational formfactors and conservation laws"
The interaction with gravity may be described by the matrix elements of
energy momentum tensor being similar to standard electromagnetic form
factors. The consequences of (flat space) conservation laws for these
form factors are explored. The gravitational formfactors are more
strongly (up to linear terms) restricted by the energy amd angular
momentum conservation, which is deeply related to Post-Newtonian
equivalence principle. The evidences that it may be valid seprately
for quarks and gluons in the nucleon are discussed.
The properties of vacuum gravitational fomfactor implied by
the broken scale invariance and their consequences
for the cosmological constant problem are considered.
