Heavy Wino-like Neutralino Dark Matter Annihilation into Antiparticles
Junji Hisano, Shigeki Matsumoto, Osamu Saito +1
The lightest neutralino is a viable dark matter (DM) candidate. In this paper we study indirect detection of the wino-like neutralino DM using positrons and antiprotons from the an…
Relic Abundance of LKP Dark Matter in UED model including Effects of Second KK Resonances
Mitsuru Kakizaki, Shigeki Matsumoto, Yoshio Sato +1
We reevaluate the thermal relic density of the Kaluza-Klein (KK) dark matter in universal extra dimension models. In particular, we consider the effect of the resonance caused by s…
Investigation of Possible Dark Matter Direct Detection in Electron Accelerators
Junji Hisano, Minoru Nagai, Mihoko M. Nojiri +1
We investigate a possibility of neutralino dark matter (DM) direct detection in the future electron accelerators. That is counting of high p_T electron recoil events by neutralinos…
Significant effects of second KK particles on LKP dark matter physics
Mitsuru Kakizaki, Shigeki Matsumoto, Yoshio Sato +1
We point out that Kaluza-Klein (KK) dark matter physics is drastically affected by second KK particles. In this work various interesting phenomena caused by the second KK modes are…
