Rest energy of each quark is 173 GeV. The total rest energy is 2 × 173 = 346 GeV. Total energy of the pair is rest energy plus kinetic energy: 346 + 50 = 396 GeV. Since energy is shared equally, each quark has 396 / 2 = 198 GeV.

The Rest Energy of Quarks: Unlocking the Hidden Power Inside Matter In the subatomic realm, quarks are the fundamental building blocks of protons, neutrons, and all matter building blocks in the universe. But did you know that each quark carries an enormous rest energy? According to modern particle physics, every quark has a rest energy of approximately 173 GeV (gigaelectronvolts), a staggering value rooted in Einstein’s famous equation E = mc². But what does this mean for the total energy within a quark pair? --- ### Understanding Rest Energy: The Intrinsic Power of Quarks
