11. Calculation of phase-space integration of sufficient inclusive processes

Peng Zhang

02/11/2020, 02:00

In this talk, I will introduce a systematic method (inverse unitarity+differential equations+auxiliary mass flow) to calculate phase-space integration for sufficient inclusive processes. With this method, we can get numerical results with high precision efficiently.

31. Introduction to parton shower

Dr Hai-Tao Li

02/11/2020, 04:00

Monte-Carlo event generators have been widely used to simulate the processes in high-energy physics. Parton shower plays a central role in Monte-Carlo event generators which provides a reliable tool to perform the leading logarithms resummation. Precision prediction from parton shower requires more theory developments such as proof of NLL resummation and NLO shower framework. Beyond the...

32. Light-ray OPE in QCD

Hao Chen

02/11/2020, 05:00

Light-ray operators play an important role in various areas of physics and, in particular, are natural language for an interesting class of observables in collider physics, including energy-energy correlator (EEC). Similar to operator product expansion (OPE) of local operators, OPE of light-ray operators governs the collinear behavior of these observables. In this talk, I will first briefly...

33. The pion-photon transition form factor at two loops in QCD

Dr Yao Ji

02/11/2020, 06:00

In this talk, I will report on our recent fully analytic calculation of the leading-power contribution to the photon-pion transition form factor at two loops in QCD. The applied techniques rely on hard-collinear factorization, together with modern multi-loop methods. I will focus both on the technical details, such as the treatment of evanescent operators, and the phenomenological...
