[Theory-seminars] Theory seminar June 14 - Hervé Dutrieux

[Astrid Hiller Blin]

Dear all,

Next Monday, June 14 at *9:00 AM* (I guess at this rate we cannot call it
"unusual time" anymore), Hervé Dutrieux will give a theory seminar on
https://bluejeans.com/801786278
<https://www.google.com/url?q=https://bluejeans.com/801786278/5878?src%3DcalendarLink&sa=D&source=calendar&usd=2&usg=AOvVaw25sgt91GOrFua-h6qKqY9J>,
see below for details.

This week too, our HUGS summer students will join the seminar. The
recordings and slides of our seminars can be found in the archives:

*Theory seminar*
Monday, June 14, *9:00 AM*

*Hervé Dutrieux* (CEA Saclay) will talk about "The deconvolution problem of
deeply virtual Compton scattering".

*Abstract:*
Generalized parton distributions are instrumental to study both the
three-dimensional structure and the energy-momentum tensor of the nucleon,
and motivate numerous experimental programmes involving hard exclusive
measurements.
Based on a next-to-leading order analysis and a careful study of evolution
effects, we exhibit non-trivial generalized parton distributions with
arbitrarily small imprints on deeply virtual Compton scattering  and Deeply
Inelastic Scattering observables.
This means that in practice the reconstruction of generalized parton
distributions from measurements, known as the deconvolution problem, does
not possess a unique solution for this channel.
I will detail in this presentation the computation of such distributions,
and discuss their relevance for the phenomenology of generalized parton
distributions.


Have a good weekend,
Astrid, Christos and Filippo
