1. The ATLAS Experiment at the CERN Large Hadron Collider
2. ATLAS uses a right-handed coordinate system where the nominal interaction point is at the center of the detector and z-axis coinciding with the axis of the beam pipe. The x-axis points from the IP to the center of the LHC, and the y-axis points upward. Cylindrical coordinate (r,ϕ) are used in the transverse plane,ϕbeing the azimuthal angle around the beam pipe. The pseudorapidity is defined in terms of the polar angleθas η=−ln tan(θ2)$\eta = - ln\;tan\left( {{\textstyle{\theta \over 2}}} \right)$.
