Query: Conformal invariance and particle aspects in general relativity   We study the breakdown of conformal symmetry in a conformally invariant
gravitational model. The symmetry breaking is introduced by defining a
preferred conformal frame in terms of the large scale characteristics of the
universe. In this context we show that a local change of the preferred
conformal frame results in a Hamilton-Jacobi equation describing a particle
with adjustable mass. In this equation the dynamical characteristics of the
particle substantially depends on the applied conformal factor and local
geometry. Relevant interpretations of the results are also discussed.
