Regularization of multi-soliton form factors in sine-Gordon model
arXiv:1111.7086 · doi:10.1016/j.cpc.2012.03.011
Abstract
A general and systematic regularization is developed for the exact solitonic form factors of exponential operators in the (1+1)-dimensional sine-Gordon model by analytical continuation of their integral representations. The procedure is implemented in Mathematica. Test results are shown for four- and six- soliton form factors.
