The very massive Higgs particle (mass 125 GeV/c2) is created when two protons traveling at equally high speeds but in opposite directions collide head‑on. The mass of a proton is 938.27 MeV/c2. In order to make a Higgs particle when they collide, each proton must have a minimum kinetic energy of 62.5 GeV. What is the minimum total energy E(min) of each proton? E(min) = ? eV In terms of the speed c of light, what speed v is each proton traveling? Calculate your answer to five significant figures. v = ? c
