22 We use a cylindrical coordinate system with z along the proton beam direction, r the perpendicular radius from the central axis of the detector, and φ the azimuthal angle. For θ the polar angle from the proton beam, we define η = - ln tan(θ/2), transverse momentum pT = p sin θ and transverse energy ET = E sin θ

27 The calorimter missing ET (ET (cal)) is defined by the sum over calorimeter towers, ET (cal) = - i Ei T ˆni, where i is calorimeter tower number with |η| < 3.6, ˆni is a unit vector perpendicular to the beam axis and pointing at the ith calorimeter tower. The reconstructed missing energy, ET, is derived by subtracting from ET (cal) components of the event not registered by the calorimeter, such as muons and jet energy adjustments. ET (cal) and ET are the scalar magnitudes of ET (cal) and ET, respectively

28 Electron charge determination is inaccurate for |η| >1.1 due to reduced tracker coverage
