Analytic Four-Point Lightlike Form Factors and OPE of Null-Wrapped Polygons
Yuanhong Guo, Lei Wang, Gang Yang
We obtain for the first time the analytic two-loop four-point MHV lightlike form factor of the stress-tensor supermultiplet in planar SYM where the momentum carrie…

Scattering approach for calculating one-loop effective action and vacuum energy
Yuan-Yuan Liu, Shi-Lin Li, Yu-Jie Chen +2
We propose an approach for calculating one-loop effective actions and vacuum energies in quantum field theory. Spectral functions are functions defined by the eigenvalues of an ope…
