For a collision of particles in the center of mass frame,

tex2html_wrap147 . tex2html_wrap148 .

let tex2html_wrap149 , then tex2html_wrap150

If 2 particles are produced, tex2html_wrap151 , tex2html_wrap152

Conservation of energy gives tex2html_wrap153 . Take tex2html_wrap154 + symmetric equation. Then solve for tex2html_wrap155 , and tex2html_wrap156 . Now can solve for momentum in center of mass frame: tex2html_wrap157 Which gives: tex2html_wrap158
