Charged vector particles in a magnetic field

The properties of exact solutions of the Proca equations in a magnetic field are investigated for arbitrary value of the phenomenological parameter $k$ that characterizes the magnetic moment of the particle. For the case $k=1$, which corresponds to the Weinberg–Salam model, a spin operator is constructed whose eigeuvalues can be used to classify the solutions. A Green's function is constructed for the Weinberg–Satam charged vector boson in the unitary gauge.
