Dear all,
I will be defending my thesis on October 14th at 8am EST, and would like 
to share a zoom link in case you are interested in attending!

Here is a summary of what I will be presenting, a big part is focused on 
my analysis for proton and neutron DVCS in deuterium in RGC.

Nucleon Structure Studies at Jefferson Lab and the Electron Ion Collider
The research programs of Thomas Jefferson Laboratory (JLab) and the 
future Electron-Ion Collider (EIC) focus on understanding the structure 
of nucleons in terms of the quarks and gluons composing them. 
Generalized Parton Distributions (GPDs), which describe how quarks and 
gluons' transverse position and longitudinal momentum are distributed 
inside nucleons, are measured with the Deeply Virtual Compton Scattering 
(DVCS) reaction in particular. The first longitudinally polarized-target 
experiment of the CLAS12 program at JLab took place in 2022-2023 
offering unique access to the DVCS beam- and target-spin asymmetries for 
protons and neutrons in deuterium. They are crucial observables to study 
GPDs and their flavor dependence. Specific analysis methods implemented 
to work with a polarized nuclear target allow to obtain preliminary 
results for the asymmetries in this thesis. In the long term, the 
measurements of reactions such as DVCS at the EIC impose strict 
requirements on the detection of the scattered electrons and photons and 
constrain the design of the electromagnetic calorimeter. It will be 
based on scintillating crystals read by Silicon Photomultipliers, that 
both have been characterized to provide guidelines for developing the 
calorimeter.

Thank you for all the shared RGC analysis fun and all your insights and 
advice! This is not a way of saying goodbye, I am planning on keeping on 
with the analysis after my defense :) Best regards, Noémie.
