摘要:

本文考虑了引力的多维修正,其引力相互作用具有较小的质量标度。假定稳定的暗物质粒子可通过与虚黑洞的相互作用发生衰变。文中估算了此类过程的衰变率。结果表明,在适当固定参数的情况下,这些超大质量粒子的衰变能够对高能宇宙射线通量作出显著贡献,尤其是在 Greisen-Zatsepin-Kuzmin 极限附近。此类粒子还可产生极高能中微子,并在现有大型水下或 ice-cube 探测器中被观测到。

英文摘要:

Multidimensional modification of gravity with a smaller mass scale of the gravitational interaction is considered. Stable by assumption dark matter particles could decay via interactions with virtual black holes. The decay rates of such processes are estimated. It is shown that with the proper fixation of the parameters the decays of these ultra-massive particles can give noticeable contribution to the flux of high energy cosmic rays in particular, near the Greisen-Zatsepin-Kuzmin limit. Such particles can also create neutrinos of very high energies observed in the existing huge underwater or ice-cube detectors.
