非粒子交换对暗物质湮灭的Sommerfeld增强

Sommerfeld Enhancement from Unparticle Exchange for Dark Matter Annihilation

Chuan-Hung Chen, C. S. Kim

摘要:

我们研究了非粒子交换对暗物质湮灭过程中可能的索末菲增强的影响。假设WIMP碰撞过程中存在非粒子交换,求解了有效势的Schr \rm \ddot{o} dinger方程,发现Sommerfeld增强因子与非粒子的尺度维数有关,为1/v^{3-2 d_{\UP} }.数值上,索末菲增强可以是{ \cal O}(10-10^{3})。

英文摘要:

We investigate the implication of unparticle exchange for the possible Sommerfeld enhancement in dark matter annihilation process. Assuming the unparticle exchange during WIMP collision, we solve the Schr\rm\ddot{o}dinger equation for the effective potential, and find that the Sommerfeld enhancement factor is dictated by the scale dimension of unparticle as 1/v^{3-2d_{\UP}}. Numerically the Sommerfeld enhancement could be {\cal O}(10-10^{3}).
