Galactic anisotropy of Ultra-High Energy Cosmic Rays produced by CDM-related mechanisms
S. L. Dubovsky, P. G. Tinyakov
We briefly review current theoretical and experimental status of Ultra-High Energy Cosmic Rays. We show that ``top-down'' mechanisms of UHE CR which involve heavy relic particle-li…

An Example of Semiclassical Instanton-Like Scattering: (1+1) Dimensional Sigma Model
V. A. Rubakov, D. T. Son, P. G. Tinyakov
A solution to the classical field equations in the massless (1+1)-dimensional O(3) sigma model is found, which describes a multi-particle instanton-like transition at high energy.…
