It is known that the massive gauge bosons W and Z have 3 states of polarization-one longitudinal and two transverse. So is it possible that by any means we can decrease it longitudinal polarization and increase its transverse component?// Or should I increase its velocity to get this required change?

  • $\begingroup$ @annav Thanks! I had seen this one. My question is if suppose I have a longitudinally polarized W boson. Can I change it to transverse polarization? $\endgroup$ – kbg Jul 7 '17 at 15:02

    $\begingroup$ As W decay very fast , no time for manipulation. You can choose events where the W polarization was longitudinal or transverse. The momentum seems to play a role and it could be used in the choicing. $\endgroup$ – anna v Jul 7 '17 at 15:26
