A Short Range Force
Gravitomagnetic and gravitoelectric forces have been studied for sometime and
tests for detecting such forces arising from the earth, are under way. We apply
similar considerations at the level of elementary particles in a formulation
using General Relativity, and deduce the presence of short range forces. A
possible candidate could be the somewhat recently detected but otherwise
mysterious short range force, mediated by massive "photons".Comment: 4 pages, TeX, Based on the paper in the Fifth International

Spin-orbit splittings in heavy-light mesons and Dirac equation
The spin-orbit splitting in heavy-light mesons is seen to be suppressed
experimentally. It is shown that it can be understood qualitatively in the
frame work of Dirac theory. An alternative derivation of a relativistic
dynamical symmetry for the Dirac Hamiltonian, which suppresses spin orbit
splitting, is also given. However it is shown that such a symmetry is not
needed since the spin-orbit splitting in Dirac theory with Coulomb like
potential (as is the case for the one gluon exchange potential in pQCD) is
small anyway.Comment: 9 pages, 1 fi
