Lorentz Transformation to Lab Frame

[math] \begin{bmatrix} E_{Lab} \\ P_{x(Lab)} \\ P_{y(Lab)} \\ P_{z(Lab)} \end{bmatrix}= \begin{bmatrix} \gamma & 0 & 0 & \gamma \beta \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ \gamma \beta & 0 & 0 & \gamma \end{bmatrix} \cdot \begin{bmatrix} E_{CM} \\ P_{x(CM)} \\ P_{y(CM)} \\ P_{z(CM)} \end{bmatrix} [/math]
