    Calculating Reaction Energy and Velocity in a Proton-Electron Collision

    Well, if you have just two particles..shouldn't it just be P_{CMS}=P_E+P_P? how do you define P_CMS?

    Calculating Reaction Energy and Velocity in a Proton-Electron Collision

    Well, this was my question. Isn't the CMS defined by \vec{p}_p+\vec{p}_e=0?

    Calculating Reaction Energy and Velocity in a Proton-Electron Collision

    Hi, i have the following exercise: At the HERA acceleratro of DESY in Hamburg electrons and protons were accelerated to E_e=27.5 GeV and E_p = 920GeV and brought to collision. A)How large is the reaction energy in the centre-of-mass system? B) What is the velocity of the HERA...
