abstract = "Exact expressions have been proposed for correlation functions of the large-N (planar) limit of the (1+1)-dimensional SU(N)×SU(N) principal chiral sigma model. These were obtained with the form-factor bootstrap.",

Here we point out that the universal coefficient C2 is proportional to the mean first-passage time of a L{\'e}vy flight in one dimension. This observation enables us to calculate C2=1/16π. {\textcopyright} 2016 American Physical Society.",
