OK Tommaso, these are the questions I would particularly like an answer to :-2.3A beam of protons of energy E1=20 GeV is made to collide head-on with a beam of protons of energy E2=5 GeV. Determine:a) the CM energy;b) the boost of the CM in the laboratory;c) the angle in the laboratory of a ultra-relativistic particle produced at 90 degrees in the CMd) the energy a beam of protons must have to gen
