comment How many sigma did the discovery of the W boson have?
Thank you. But isn't a number of 22 over a zero background almost an infinite number of sigmas?

comment What does spin 0 mean exactly?
The formula for the return angle is also valid for spin 2: such systems return to their original state after a rotation by pi.

comment Can the mass of longitudinal and transverse W bosons be measured separately?
Your request is not helpful for the answer. The question was: Is there a way that the existing data from the LHC, the LEP or the Tevatron can be used to check that longitudinal and transverse mass differ? Or maybe it has already been checked?

Isn't 'transversal' and 'perpendicular' defined with reference to the beam direction? Can't a particle be polarized in any direction in between, especially if the beam is not fully polarized?

comment Can the mass of longitudinal and transverse W bosons be measured separately?
Anna, but polarization changes continuously, so one would expect a smooth superposition of Gaussians, not a secondary peak. To see two distinct peaks, one would need to separate exact longitudinal and exact transversal polarization only, leaving out all the intermediate orientations. Is that possible?
