متن کاملThe Passage of Ultrarelativistic Neutralinos through Matter
The origin of the most energetic cosmic ray events, with E ∼ 1020 eV, remains mysterious. One possibility is that they are produced in the decay of very massive, long–lived particles. It has been suggested that these so–called “top–down scenarios” can be tested by searching for ultrarelativistic neutralinos, which would be produced copiously if superparticles exist at or near the TeV scale. In ...

متن کاملDensity Matrix Kinetic Equation Describing a Passage of Fast Atomic Systems through Matter
The quantum-mechanical consideration of a passage of fast dimesoatoms through matter is given. A set of quantum-kinetic equations for the density matrix elements describing their internal state evolution is derived. It is shown that probabilistic description of internal dynamics of hydrogen-like atoms is impossible even at sufficiently low energies because of the “accidental” degeneracy of thei...
