As A is a pseudo-scalar, Z an axial vector and h being a scalar, it looks like the spins are not balanced on both sides. Is it related to the longitudinal mode of Z boson?

  • So your not using A as it usually stands for as EM gauge field? What are you using it as? – AHusain Jul 28 '16 at 04:43
  • No. The A here doesn't stand for the EM gauge field. The A here refers to the pseudo-scalar Higgs boson in MSSM. – RKB Jul 29 '16 at 09:25
