[Theory-seminars] cake seminar tomorrow at 1pm room L102

[Vincent Mathieu]

Dear all, 

tomorrow Raza Sufian will give a cake seminar at 1pm room L102 (please note the change of time)
See the title and abstract below. 

As the semester starts, we are looking for volunteers for the cake seminar series. 
Please fill the Doodle with your availabilities:

Title: Calculation of Pion Valence Distribution Using Hadronic Lattice Cross Sections

abstract:

Recently, it has been shown by Ma & Qiu [PRL 120 (2018) no.2, 022003)] that a class of coordinate-space-separated non-local hadronic matrix elements, computable directly in lattice QCD, can be factorized into parton distribution functions with calculable coefficients, in the same manner as the hadronic cross sections measured in an experiment. In this talk, I will present the progress of the calculation of pion valence distribution using this hadronic “Lattice Cross Sections” formalism.
I will also report an upcoming calculation of the determination of weak neutral current (WNC) axial form factor (G^Z_A) and its application to neutrino-nucleon elastic scattering cross section.
