Abstract
Almost all of the visible matter in the universe, including the stars, the planets, and us, is built from protons and neutrons (collectively called nucleons), which are found in the nucleus of an atom.
The nucleons themselves are not a fundamental form of matter since they are composed of other particles, called quarks and gluons, and thus nucleons have a complex internal structure. Both theory and technology have now reached a point where human is capable of exploring the inner dynamics and structure of nucleons and nuclei at the sub-femtometer distances. In this talk, I will discuss how we explore the inside of nucleons and also explain what we know about the quark and gluon substructure and their interactions.
I will describe some interesting effects that occur because of the strange and unanticipated behavior of these particles, and how these phenomena provide a rich avenue for current and future research including connections and overlaps with other fields in physics.
Bio
Dr. Alexei Prokudin is a nuclear physicist who primarily focuses on theoretical sub-atomic nuclear physics, hadron structure and Quantum Chromo Dynamics. The main theme is three-dimensional structure of the proton and the neutron. The aim is to learn the internal structure of the nucleon from the point of view of quarks and gluons. His experience has been mainly in the theoretical and phenomenological interpretation of experimental data from international and national facilities such as CERN, BNL, Jefferson Lab, SLAC, KEK, Fermilab and others in terms of the so-called Transverse Momentum Dependent distributions that encode three-dimensional structure of the nucleon in the momentum space.
Dr. Prokudin is an assistant professor of Physics at Penn State Berks. This position is a bridge appointment with Jefferson Lab, the goal of the bridge position is to strengthen nuclear physics research conducted in the United States by facilitating collaborations between Jefferson Lab and faculty at research universities.
Dr. Prokudin is a CO-PI of Topical Collaboration US DOE TMD grant of more than $2M and he was awarded an individual NSF grant of $150,000 in 2016.
Dr. Prokudin earned his doctorate from the Institute for High Energy Physics in Protvino, Russia, in 2000. Prior to joining PSU Berks in August 2015 Dr. Prokudin was a Postdoctoral Researcher at University of Turin, INFN Turin, and at Universita' del Piemonte Orientale 2001-2009 and a Staff Scientist at Theory Center of Jefferson Lab 2009-2015.
