报告人： 刘正文 博士（Université catholique de Louvain, Belgium） 报告摘要：The Cachazo-He-Yuan formalism expresses the S-matrix as a multiple integral over the moduli space of Riemann spheres with marked points, which is localised by a set of the scattering equations, for various field theories in any number of spacetime dimensions. In this talk, I will give a short introduction to the basic aspects of the scattering equations and CHY formulation, and then will also present some recent developments in this field with a special focus on four-dimensional spacetime. |
