    • We use a standard right-handed coordinate system. The nominal collision point is the center of the detector with coordinate (0, 0, 0). The direction of the proton beam is the positive +z axis. The +x axis is horizontal, pointing away from the center of the Tevatron ring. The +y axis points vertically upwards. The polar angle, θ, is defined such that θ=0 is the +z direction. The rapidity is defined as y=-ln[(E+pZ)/(E-pZ)], where E is the energy and pZ is the momentum component along the proton beam direction. Pseudorapidity is defined as η=-ln(tanθ2). φ is defined as the azimuthal angle in the plane transverse to the proton beam direction.

    • Since the longitudinal component of the momentum of the neutrinos is not measured, the measured properties of the W boson candidates are limited to their transverse energy and transverse mass, defined as MT=(p{combining long solidus overlay} T+pTℓ)2-(p{combining long solidus overlay} x+pxℓ)2-(p{combining long solidus overlay} y+pyℓ)2 where p{combining long solidus overlay} T is the magnitude of the missing transverse energy vector, pTℓ is the transverse momentum of the lepton and pxℓ and pyℓ (p{combining long solidus overlay} x and p{combining long solidus overlay} y) are the magnitude of the x and y components of the lepton's momentum (missing transverse energy) respectively.
