Name: Seongchan Park Institution: IPMU Title: Kaluza-Klein Dark Matter Key Words: Kaluza-Klein, dark matter, extra dimension, Pamela, Fermi Abstract: Kaluza-Klein dark matter(KK DM) is a candidate of WIMP CDM in extra dimension models with a geometrical symmetry, called KK-parity. We explore the properties of KK DM and show how it fits the data from Pamela and Fermi observations of cosmic positron and photon.
