太陽與超新星微中子的暗物質米赫耶夫-斯米爾夫-沃芬斯坦效應

Dark Matter Induced Mikheyev-Smirnov-Wolfenstain Effect in The Sun And Core-Collapse Supernovae

指導教授 : 張維甫

摘要


我們計算了在太陽與超新星微中子受到暗物質的米赫耶夫-斯米爾夫-沃芬斯坦效應。然而,若暗物質不會自我湮滅,例如,不對稱暗物質,才會有足夠大的效應。從太陽微中子觀測實驗的數據,在暗物質質量小於四十百萬電子伏特的範圍,我們得到一個很強的對於微中子與暗物質之間作用力大小的限制條件。在核塌陷超新星中,我們發現只有在超新星的位置很靠近銀河系中心或暗物質與微中子作用力夠強才有機會偵測到這個額外的效應。

並列摘要


We studied the dark matter induced Mikheyev-Smirnov-Wolfenstein eect on neutrino oscillations in the Sun and the core-collapse supernovae. However, to have sizable eect, we found that the dark matter cannot self-annihilate, for instance, the asymmetric dark matter. From the solar neutrino data, we found strong constraint on the interaction between dark matter and neutrino for asymmetric dark matter with mass less than 40 GeV. For supernovae, we found that the additional eect would be detectable only if the supernova sits close to the Galactic center or the interaction between dark matter and neutrinos is strong enough.
