{wiki=Pole_mass}
The term "pole mass" is commonly used in the context of particle physics and refers to the mass of a particle as it would be measured in a specific way. More precisely, the pole mass is defined as the mass of a particle that corresponds to the position of the pole of the particle's propagator in a quantum field theory. The propagator describes how the particle behaves in terms of its interactions with other particles.
