D 63:054019 (2001) [19] The important kinematic variables are the rapidity y = 1 2 ln E + p$_{z}$ E − $_{p$_{z}$}$, the azimuthal angle φ = tan − 1 p$_{y}$ p$_{x}$ and transverse momentum p$_{T}$ = √ p 2 x + p 2 y where a particle or jet has a 4-momentum ( E, p$_{x}$, p$_{y}$, p$_{z}$ ) and the positive z is defined by the proton beam’s direction, positive y is up and the x direction is that required to make a right-handed coordinate system. In addition, the pseudorapidity η = − ln[tan( θ/ 2)] is sometimes used, where θ is the polar angle, measured with respect to the proton beam axis. The boost rapidity is defined as y$_{boost}$ = 0 . 5 | y$_{1}$ + y$_{2}$ | . [20] Field R, Fermilab ME/MC tuning workshop, Fermilab (2002) [21] Field R, et al.
