Abstract
The quantum field model of unstable particles with a smeared mass is suggested to describe the finite-width effects. Within the framework of this model, we derive the convolution formula for a width and factorized formula for a cross-section. The phenomenological consequences of the mass smearing is discussed in the various fields of particle physics.
