Magnetic quadrupole moment of $W$-boson in Kobayashi-Maskawa model

Abstract

Magnetic quadrupole moment of $W$-boson in Kobayashi-Maskawa model, I.B. Khriplovich and M.E. Pospelov, BUDKERINP 93--88 Due to CP-invariance violation a vector particle can acquire T- and P-odd electromagnetic moment, magnetic quadrupole one. The W-boson magnetic quadrupole moment is calculated in the Kobayashi-Maskawa model. This is the only known CP-odd moment arising in this model in two-loop approximation.
