与银河系cosmic ray数据一致的Higgsino暗物质模型和在LHC-7发现的可能性

Higgsino dark matter model consistent with galactic cosmic ray data and possibility of discovery at LHC-7

Ning Chen, Daniel Feldman, Zuowei Liu, Pran Nath, Gregory Peim

摘要:

在扩展的超引力大统一(SUGRA)模型下,提出了一个含Higgsino暗物质的PAMELA正电子过剩的解。该模型是符合最近设置的费米-LAT的光子约束,并产生正电子以及反质子通量与PAMELA实验一致。考虑的SUGRA模型有一个扩展的隐藏部门,额外的自由度,允许满足遗物密度与WMAP一致。Higgsino模型也与CDMS-II和XENON 100的数据一致,并且可以在LHC-7上以1 fb^(-1)的光度进行验证。这些模型可以在几个方面进行测试。

英文摘要:

A solution to the PAMELA positron excess with Higgsino dark matter within extended supergravity grand unified (SUGRA) models is proposed. The models are compliant with the photon constraints recently set by Fermi-LAT and produce positron as well as antiproton fluxes consistent with the PAMELA experiment. The SUGRA models considered have an extended hidden sector with extra degrees of freedom which allow for a satisfaction of relic density consistent with WMAP. The Higgsino models are also consistent with the CDMS-II and XENON100 data and are discoverable at LHC-7 with 1 fb^(-1) of luminosity. The models are testable on several fronts.
