On gravitational flow in the Relativistic Theory of Gravitation
A definition of the gravitational flow and a short description of the recipe
of its calculation are presented.Comment: 6 page
On Boundedness of the Admissible Time Slowing Down by the Gravitational Field
It is shown that there exists, in the field theory of gravitation, contrary
to the General Theory of Relativity (GTR), a bound for admissible time slowing
down by the gravitational field which excludes a possibility of unbounded
compression of matter by the gravity forces.Comment: 5 page
Impossibility of Unlimited Gravitational Collapse
It is shown that the gravitational field, as a physical field developing in
the Minkowsky space, does not lead to unlimited gravitational collapse of
massive bodies and, hence, excludes a possibility of the formation of the
``black holes''.Comment: 6 page
B_c Meson Production in Nuclear Collisions at RHIC
We study quantitatively the formation and evolution of B_c bound states in a
space-time domain of deconfined quarks and gluons (quark-gluon plasma, QGP). At
the Relativistic Heavy Ion Collider (RHIC) one expects for the first time that
typical central collisions will result in multiple pairs of heavy (in this case
charmed) quarks. This provides a new mechanism for the formation of heavy
quarkonia which depends on the properties of the deconfined region. We find
typical enhancements of about 500 fold for the B_c production yields over
expectations from the elementary coherent hadronic B_c-meson production
scenario. The final population of bound states may serve as a probe of the
plasma phase parameters.Comment: 9 Pages, 11 Postscript Figure
X-ray emission during the muonic cascade in hydrogen
We report our investigations of X rays emitted during the muonic cascade in
hydrogen employing charge coupled devices as X-ray detectors. The density
dependence of the relative X-ray yields for the muonic hydrogen lines (K_alpha,
K_beta, K_gamma) has been measured at densities between 0.00115 and 0.97 of
liquid hydrogen density. In this density region collisional processes dominate
the cascade down to low energy levels. A comparison with recent calculations is
given in order to demonstrate the influence of Coulomb deexcitation.Comment: 5 pages, Tex, 4 figures, submitted to Physical Review Letter
