PENTAGON OPE RESUMMATION IN N = 4 SYM: ONE EFFECTIVE PARTICLE AND MHV AMPLITUDE

摘要

We present the technique for resummation of flux tube excitations series arising in pentagon operator expansion (OPE) program for polygonal Wilson loops and amplitudes in N=4 SYM. Here, we restrict ourselves with contributions of one-particle effective states and illustrate our technique on the example of one-loop MHV_6 amplitude.
