Lebanon Valley College Physicist Dr. Daniel Pitonyak Part of a U.S. Department of Energy $1.95 Million Grant

Brookhaven Lab to Lead New ‘Saturated Glue’ Theory Collaboration

The U.S. Department of Energy’s Brookhaven National Laboratory announced a nearly $2 million grant to a group of researchers who are part of the SURGE (SatURated GluE) Topical Theory Collaboration. The five-year grant will enable scientists from 16 colleges, universities, and national laboratories to develop calculations and a framework for discovering and exploring a saturated state of gluons, the particles that hold together everything we see. Dr. Daniel Pitonyak, LVC assistant professor of physics, is a member of SURGE.

According to Brookhaven’s announcement, SURGE will aid in the discovery and exploration of a saturated state of gluons. These aptly named particles carry the nuclear strong force, acting as the ‘glue’ that holds together quarks, the building blocks of all visible matter. By understanding gluons’ ability to split and recombine and potentially reach a state of saturation, scientists hope to gain deeper insight into the strong force and the role gluons play in generating the mass, spin, and other properties of hadrons—composite particles made of quarks, such as the protons and neutrons of atomic nuclei.

“I am excited to be a member of this collaboration,” said Dr. Pitonyak, who received a National Science Foundation grant in 2020 to fund his theoretical nuclear physics research.

“I will conduct computational work to calculate how much quarks and gluons at very high energy contribute to the proton’s spin, a fundamental quantum mechanical “rotation” carried by all particles. This grant will provide additional support and collaborative opportunities with top institutions in the country for my research and the LVC students who work with me,” added Dr. Pitonyak.

SURGE aims to develop calculations and a theoretical framework for discovering this unique saturated form of gluonic matter. Such a saturated state is predicted by the theory of quantum chromodynamics (QCD) to be observable in particles accelerated to high energies in particle colliders such as the Relativistic Heavy Ion Collider (RHIC) at Brookhaven Lab, the Large Hadron Collider (LHC) at Europe’s CERN laboratory, and the future Electron-Ion Collider (EIC) at Brookhaven.

“Our goal is to advance calculations to high precision and develop a comprehensive framework that allows us to compare our theoretical understanding of gluons’ behavior to a wide range of experimental data from RHIC and the LHC and make predictions for what we expect to see at the future EIC,” said Bjoern Schenke, the Brookhaven theorist who will serve as Principal Investigator for the SURGE collaboration.

Dr. Pitonyak Publishes NSF-funded Research with Miller ’21, Malda ’22, and Colleagues

Dr. Daniel Pitonyak, assistant professor of physics, Josh Miller ’21 (physics and mathematics), Michael Malda ’22 (physics and analytical finance), and physicists from Penn State Berks and Thomas Jefferson National Accelerator Facility published “Updated QCD global analysis of single transverse-spin asymmetries: Extracting H~, and the role of the Soffer bound and lattice QCD”.  The article appeared in the peer-reviewed journal Physical Review D, a leading journal in elementary particle physics research. The authors analyzed additional theoretical and experimental constraints on phenomena in high-energy collisions called single transverse-spin asymmetries and showed their consistency with the underlying mechanism of quark-gluon-quark correlations.  The research was funded by Dr. Pitonyak’s National Science Foundation grant.

Dr. Pitonyak Gives Invited Talks at UVA and Italy Conferences

Dr. Daniel Pitonyak, assistant professor of physics, presented a pair of invited talks based on research supported by his recent National Science Foundation (NSF) grant to study the 3-dimensional structure of hadrons. Dr. Pitonyak presented “Updated QCD Global Analysis of SSAs: New Experimental Data and Constraints” as part of the QCD Evolution Workshop, which was held at the University of Virginia. He followed that presentation with a virtual invited talk—”Updated QCD Global Analysis of SSAs: H~, the Soffer Bound, and Lattice gT”—at the 6th International Workshop on Transverse Polarization Phenomena, which was hosted by Almo Collegio Borromeo in Pavia, Italy.

Dr. Veenhuizen Presents at National Conference on Glass Science

Dr. Keith Veenhuizen, assistant professor of physics, presented research at the 2022 Glass and Optical Materials Division meeting in Baltimore, Md. The presentation was based on results of a student-faculty research project undertaken by Olivia Magneson ’23 with Dr. Veenhuizen. The talk, “Phase-selective laser-induced crystallization of lead bismuth gallate glass,” reports how several crystal phases form preferentially at different temperatures in lead bismuth gallate glass. By varying the power and scanning speed of the laser irradiating the glass, the temperature profile can be controlled, through which the desired crystal phase can be formed. This talk was given at the Laser Interactions with Glasses session, which was organized by Dr. Veenhuizen in collaboration with Dr. Casey Schwarz of Ursinus College.

Dr. Walck Publishes Computational Physics Textbook

Dr. Scott N. Walck, professor of physics, published “Functional Programming for Physics Geeks,” with No Starch Press. The book, a culmination of a decade of Dr. Walck finding innovative ways to teach computational physics to LVC students, is available for pre-order at Amazon and Barnes and Noble. “Functional Programming for Physics Geeks” is the first book in the world to combine functional programming with physics at the undergraduate level.
