Conference Hall 322, ITP/理论物理所322报告厅 Abstract : Motivated by the recent observation of the high energy electron and positron excesses in cosmic ray by PAMELA and ATIC/PPB-BETS, we suggest an anomaly-free scenario for the universal extra dimension that localizes the SM quarks and splits the spectrum of KK quarks and KK leptons. When the SM quarks are "well localized" at the boundaries, the most stringent bound of the model
(1/R > 510 GeV) is from the resonance search for the Tevatron dijet channels. Even at the early stage of LHC, one can discover the second KK gluon up to 4 TeV.
