SUMMARY
The discussion centers on calculating the invariant mass of electron-proton (ep) collisions at HERA, where 30 GeV electrons collide with 820 GeV protons. The correct invariant mass is determined to be 314 GeV. The participants clarify the use of the equation M^2 = (E1 + E2)^2 - (p1 + p2)^2, emphasizing the importance of considering the direction of momentum in the calculations. The solution involves applying the energy-momentum relation E^2 = p^2 + m^2 to find the correct momentum values.
