Description

Scattering amplitudes involving multiple partons are plagued with infrared singularities. The soft singularities of the amplitudes are captured by the soft function which is defined as the vacuum expectation value of Wilson line correlators. Renormalization properties of soft function allows us to write it as an exponential of the finite soft anomalous dimension. An efficient way to study the soft function is through a set of Feynman diagrams known as Cwebs (webs). In this talk I will discuss the progress that has been made by our group in the last couple of years in understanding the structure and the building blocks of Cwebs.
