用HAWC探测暗物质

Dark Matter Searches with HAWC

Tolga Yapici, Andrew J. Smith

摘要:

高海拔水切伦科夫(HAWC)伽马射线天文台是一个宽视场天文台,对0.5 TeV - 100 TeV伽马射线和宇宙射线敏感,位于墨西哥普埃布拉州,海拔4100米。HAWC天文台利用暗物质湮灭和衰变产生的GeV-TeV光子对暗物质进行了间接搜索,考虑了各种来源,包括矮球状星系、M31星系和室女星系团,以及使用dSphs的综合限制。HAWC没有发现这些来源有统计学意义的过剩。我们在暗物质质量超过1 TeV时寻找暗物质湮灭和衰变。我们将介绍湮没截面和衰变寿命极限。

英文摘要:

The High Altitude Water Cherenkov (HAWC) gamma-ray observatory is a wide field-of-view observatory sensitive to 0.5 TeV - 100 TeV gamma-rays and cosmic-rays in the State of Puebla, Mexico at an altitude of 4100m. The HAWC observatory performed an indirect search for dark matter via GeV-TeV photons resulting from dark matter annihilation and decay considering various sources, including dwarf spheroidal galaxies (dSphs), the M31 galaxy and the Virgo cluster, as well as a combined limit using the dSphs. HAWC has not seen statistically significant excess from these sources. We searched for dark matter annihilation and decay at dark matter masses above 1 TeV. We will present the annihilation cross-section and decay lifetime limits.
