报告人简介：
Wen-Jie Ma is an Assistant Professor at Shanghai Institute for Mathematics and Interdisciplinary Sciences (SIMIS). Prior to joining SIMIS, he served as a Postdoctoral Research Scholar at Yau Mathematical Sciences Center of Tsinghua University and Yanqi Lake Beijing Institute of Mathematical Sciences and Applications (BIMSA). He obtained his Ph.D in physics at Laval University in 2021.
Professor Ma’s current research interests mainly foucs on conformal field theory and the principle of holography, including non-perturbative booststrap program, AdS/CFT, dS/CFT as well as celestial
holography.
讲座摘要：
Assuming the existence of crossing symmetric celestial OPE, we propose a method to construct four-point massless scattering amplitudes in the framework of celestial holography. This method does not require knowledge of the Lagrangian in the bulk, and instead relies only on CFT techniques and a remarkable property: scattering amplitudes can be derived from a single conformal block coefficient in celestial CFT. Utilizing this method, we construct the MHV amplitudes in pure Yang-Mills, pure gravity, and Einstein-Yang-Mills theories.
