consis antiproton (in other words, a proton and antiproton are created and the two original protons are still present). Each particle has a rest energy of 938 MeV. (The antiproton was discovered in 1955 by performing this experiment.) (a) If the experiment is carried out in the lab frame, with one proton incident on a target proton at rest, find the minimum kinetic energy that the incident proton must have for the reaction to proceed. (b) If the experiment is carried out in the center-of-mass (CM) frame, with two colliding beams of protons, find the minimum kinetic energy that each of the two initial protons must have for the reaction to proceed. (c) Comment on the comparison between (a) and (b).

6. A collision between two protons results in a final state consisting of three protons and one antiproton (in other words, a proton and antiproton are created and the two original protons are still present).
