Solving The N-Body Problem in (2+1)-Gravity
A. Bellini, M. Ciafaloni, P. Valtancoli
We construct a non-perturbative, single-valued solution for the metric and the motion of interacting particles in -Gravity. The solution is explicit for two particles with…
(2+1)-Gravity with Moving Particles in an Instantaneous Gauge
A. Bellini, M. Ciafaloni, P. Valtancoli
By defining a regular gauge which is conformal-like and provides instantaneous field propagation, we investigate classical solutions of (2+1)-Gravity coupled to arbitrarily moving…
Non-Perturbative Particle Dynamics
A. Bellini, M. Ciafaloni, P. Valtancoli
We construct a non-perturbative, single-valued solution for the metric and the motion of two interacting particles in ()-Gravity, by using a Coulomb gauge of conformal type. T…
Gravitino one-loop contribution to Planckian Scattering
A. Bellini, M. Ademollo, M. Ciafaloni
Corrections to the semiclassical approximation in nearly forward Planckian energy collisions are here reconsidered. Starting from the one-loop superstring amplitude, we are able to…
