Bion non-perturbative contributions versus infrared renormalons in two-dimensional ℂP N − 1 models
Abstract We derive the semiclassical contributions from the real and complex bions in the two-dimensional ℂP N − 1 sigma model on ℝ×S 1 with a twisted boundary condition. The bion configurations are saddle points of the complexified Euclidean action, which can be viewed as bound states of a pair of...
