SUMMARY
In the discussion, it is confirmed that massive bosons, such as the W and Z bosons, possess three polarization states (m_s = 1, 0, -1), while massless bosons, like photons, have only two polarization states (m_s = 1, -1). These polarization states are indeed equivalent to helicity states, with the caveat that helicity for massive particles is not Lorentz invariant. Thus, the W and Z bosons exhibit three helicity states, while the photon has two.
