THE ACCELERATION AND PROPAGATION OF STRANGELETS IN THE GALAXY - NUMERICAL SIMULATIONS

The diffusive propagation of strangelets through the interstellar medi um and their interactions with Galactic supernova remnants are studied with the help of three-dimensional numerical simulations. Using the e vents of the Sanriuku Balloon Center (HECRO-81) experiment and, altern atively, the reported Centauro events to normalize the flux onto the E arth, the confinement time, injection energy, differential spectrum, a nd fractional mass in the Galaxy are addressed. We discuss the consist ency of the results with both the popular compact binary coalescence a nd Type II supernova injection scenarios. We find, in agreement with p revious estimates, that if any of those tentative identifications of s trangelets is correct, the Galaxy is inevitably contaminated with stra ngelets, and there is no room for neutron stars (thus, either strange stars can glitch, or the existence of strangelets in cosmic rays can b e ruled out). The simulations may prove useful to guide future searche s of strangelets by new experiments.
