Abstract EN
The propagators of unstable particles are considered in framework of the convolution representation.
Spectral function is found for a special case when the propagator of scalar unstable particle has Breit-Wigner form.
The expressions for the dressed propagators of unstable vector and spinor fields are derived in an analytical way for this case.
We obtain the propagators in modified Breit-Wigner forms which correspond to the complex-mass definition.
