报告摘要:

Scattering amplitudes with spinning particles are shown to decompose into multiple copies of simple building blocks to all loop orders, which can be used to efficiently reduce these amplitudes to sums over scalar integrals. Absence of unphysical kinematic singularities cleanly exposed by the method uncover novel consistency relations among master integrals and their coefficients. Analytic results are obtained for the five gluon, two loop, and four gluon, three loop planar scattering amplitudes in pure Yang-Mills theory as well as for leading singularities to even higher orders.

报告人简介:

Hui Luo got her PhD degree from Zhejiang University in 2013. Then she started her postdoc position in SISSA/Padua University, Italy. After that, she continued her research on high energy physics in Hamburg University and Johannes Gutenburg University of Mainz in Germany till the middle of 2018. Currently, Hui Luo is an associate professor in Graduate School of China Academy and Engineering Physics, Beijing. She is now focusing on developing methods of high-order quantum corrections as well as the insight and implementations of Neural Networks in physics.
