Still the collision formula from a lab frame doesn't help parlour tricks like pole and barn Replace the CW ion with a pole. Replace the CCW ion with a barn and they get the same gamma.

No, that's not correct. The *relative* velocity is the velocity of one particle as seen by the other. This is not the velocities of the particles as seen in the lab, which has already been pointed out is 99.9957% of c. > > Colliers would be no better than single > beams otherwise. Relative velocity is not the figure of merit, and not the reason to build colliders vs fixed target machines. Center of mass energy is. And I showed you how to do that calculation, and I also gave you a reference that shows you the formulas you should use, including applications in both cases. Please read them. Note that in a fixed target experiment, one of the p's (say, p2) is zero, and so the vector sum of the momentum is not zero, and so the center of mass energy is reduced, compared to a collider experiment where |p1+p2| = 0. > > > > > The center of mass energy squared is given by the relation > > (E1+E2)^2 - |p1+p2|^2, where the first sum is a scalar sum and the > > second is the scalar magnitude of a vector sum.

It is measured by virtue of the fact that the measured cross sections and decay distributions are identical in cases where the relative velocity of the particles in a collider environment is identical to the relative velocity of the particles in a different fixed target environment. Relativistic kinematics has been experimentally tested and confirmed through *measurement*. It is not just hypothetical stuff. > I hear the > Alpine mountaineer that volunteer to ride > the ion with a police radar had to cancel due > to illness in his dairy. > > > > > All of these calculational formulas are found in public archives, > > which you should take care to bookmark, read, and learn how to use, > > since it is plain that you don't know what you're doing when you look > > at a wiki article and incorrectly quote it, let alone derive incorrect > > conclusions from it.
