Search for universal extra dimensions in $p\bar{p}$ collisions

We present a search for Kaluza-Klein (KK) particles predicted by models with universal extra dimensions (UED) using a data set corresponding to an integrated luminosity of 7.3 fb

^{-1}

, collected by the D0 detector at a

p\bar p

center of mass energy of 1.96 TeV. The decay chain of KK particles can lead to a final state with two muons of the same charge. This signature is used to set a lower limit on the compactification scale of

R^{-1}>260

GeV in a minimal UED model.

The D0 detector coordinate system is right-handed with the z axis pointing in the proton beam direction. The y axis points upward and the azimuthal angle φ is measured from the x axis. Pseudorapidity is defined as η = - ln[tan(θ/2)], where θ is the polar angle

Missing transverse energy is defined as ET = - i (Ei T,x, Ei T,y), where Ei T,x = Ei sin θi cos φi, Ei T,y = Ei sin θi sin φi. Here Ei is the energy deposited in ith calorimeter cell and the angles θi and φi define the direction from the origin of the coordinate system to the ith calorimeter cell. We also define ET ≡ |ET |
