Abstract:
It has been known since the 1930’s that protons are not “point-like” elementary particles, but rather have a substructure. Today, we know from Quantum Chromodynamics (QCD) that protons are made from quarks and gluons, with gluons being the elementary force carriers for strong interactions. Quarks and gluons are collectively called as partons. The substructure of the protons can be described in terms of parton correlation functions such as Form Factors, (1D) Parton Distribution Functions (PDFs) and their 3D generalizations in terms of Transverse Momentum-dependent parton Distributions and Generalized Parton Distributions. All these functions can be derived from the Wigner functions, which simultaneously encode the spatial and momentum distribution of partons inside protons. In this talk, we provide an insight into all these functions from the point of view of their accessibility in experiments as well as from their direct calculation within lattice formulations of QCD.
About me:
I am originally from India. I obtained a Bachelor’s degree in Physics from the University of Calcutta, and a Master’s degree in Physics from Indian Institute of Technology (IIT) Delhi. In 2015, I joined Dr. Andreas Metz’s group at Temple University (Philadelphia) for a Ph.D. During my Ph.D., I gained expertise in Quantum Chromodynamics. My research interests are to search for observables sensitive to partonic Wigner functions, apply Euclidean-correlator approaches to extract PDFs/GPDs from lattice QCD, perform global QCD analyses of data, and understand anomalies in Quantum Field Theories.
