Limit of Energy in Lab Frame

The t quantity is known as the square of the 4-momentum transfer

[math]\displaystyle{ t \equiv \left({\mathbf P_1^*}- {\mathbf P_1^{'*}}\right)^2=\left({\mathbf P_2^{*}}- {\mathbf P_2^{'*}}\right)^2 }[/math]

temp

[math]\displaystyle{ {\mathbf P_1^{2}}+ {\mathbf P_1^{'2}}-2 {\mathbf P_1} {\mathbf P_1^{'}} }[/math]

[math]\displaystyle{ 2m^2-2E_1E_1^'+2 {\vec p_1} {\vec p_1^'} }[/math]
