Zapraszamy na seminarium 11.6.2024

Dear All,
 
We have the pleasure of inviting you to the Particle Theory Seminar on Tuesday,
June 11 at 12:15, which will be given by


Herve Dutrieux (William & Mary University, Wiliamsburg, USA)


entitled

“Perturbation theory and the calculation of parton distributions on the lattice".

Abstract:

I will present how the perturbative matching used to relate space-like non-local matrix element computed on the lattice to parton distributions is inconvenient due to the low typical scale of the calculations. I will discuss our control of power corrections and lattice artifacts in a recent generalized parton distribution calculation and argue that, once those are under control, alternatives to the simple perturbative matching can be considered.

 


The speaker will be on-line, local participants are invited to meet in the seminar room D-2-02.
