Transverse mass

The transverse mass is a useful thing to define for use in particle physics. In natural units it is:::$m\_\{T\}^2\; =\; m^2\; +\; p\_\{x\}^2\; +\; p\_\{y\}^2\; ,$:where the z-direction is along the beam pipe and so:$p\_x$ and $p\_y$ are the momentum perpendicular to the beam pipe and:$m$ is the mass
