The Institute for Nuclear Theory, a national resource funded by the US Department of Energy and the University of Washington, provides an environment for scientists to advance the frontiers of subatomic physics. Scientific meetings at the INT attract hundreds of visitors annually from around the world to hasten breakthrough discoveries through collaborations.

Current and Upcoming Programs

October 30 - November 1, 2019: Hadronic Parity Nonconservation II (INT-19-76W)

S. Gardner, W. Haxton, B. Holstein

Recent work applying large-Nc QCD to hadronic parity violation has yielded an organization of the five low-energy SP (or Danilov) amplitudes into a hierarchy, with two of the associated low-energy constants (LECs) of lower order (LO or NLO) and three others of next-to-next-to-leading-order (NNLO).

November 4 - 8, 2019: Fundamental Symmetries Research with Beta Decay (INT-19-75W)

B. Filippone, A. Garcia, R. Gupta, A. Young

This is a five day workshop to identify and assess the global, current and planned beta decay research over the next five to ten years. The impact of these measurements is defined by theoretical work in diverse areas of nuclear and particle theory, including conventional nuclear structure, electroweak radiative corrections, lattice calculations of nucleon properties and high energy phenomenology.

January 13 - February 7, 2020 : Neutrinos from the Lab to the Cosmos (INT-20-1a)

K. Abazajian, J. Formaggio, C. Lunardini

We are entering an era where we are expanding our knowledge of the properties of neutrinos. Laboratory oscillation experiments are solidifying the basic properties of neutrinos. Astrophysical observations of neutrinos-whether of ultra high energy cosmic neutrinos or of supernovae-provide a new window to their properties and their origin. Read more ...


March 9 - April 10, 2020: The r-process and the nuclear EOS after aLIGO's third observing run (INT-20-1b)

D. Radice, J. Read, L. Roberts

Neutron star mergers provide an extreme test bed for the properties of dense matter and they may provide clues about how the heaviest elements in our solar system were produced. Read more ...


May 11 - June 5, 2020: Chirality and Criticality: Novel Phenomena in Heavy-Ion Collisions (INT-20-1c)

J. Liao, M. Stephanov, Z. Xu, H-U. Yee

The Relativistic Heavy Ion Collider (RHIC) in Brookhaven National Laboratory are currently searching for the novel phenomena of chirality and criticality. The isobaric collision experiment, contrasting the RuRu and ZrZr colliding systems, is specifically designed to probe potential signals of the Chiral Magnetic Effect (CME), that will be the crucial test for the topological aspects of QCD and other associated phenomena.

Highlights from Recent Programs

July 1 - August 2, 2019 : Nuclear Structure at the Crossroads

R.J. Furnstahl, H-W. Hammer, A. Schwenk

Effective Field Theories (EFTs) applied to nuclei and nuclear matter have had many phenomenological successes. In particular, nuclear interactions derived from chiral EFT and advances in nuclear many-body techniques have enabled rapid progress in ab initio nuclear structure calculations up to mass numbers A ~ 100.

April 29-May 24, 2019 : Origins of Correlations in High Energy Collisions

A. Dumitru, C. Loizides, B. Schenke, S. Schlichting

The program "Origins of Correlations in High Energy Collisions" focused on the physical origins of multi-particle correlations in high energy collisions of hadrons and nuclei, as well as in electron-hadron/nucleus collisions. Strong focus lay on the understanding of 2- and 4- particle correlations in collisions of protons with heavy nuclei (and other protons) at RHIC and LHC, as well as in collisions of other very light nuclei with heavy nuclei at RHIC..

March 18 - April 19, 2019 : Quantum Turbulence: Cold Atoms, Heavy Ions, and Neutron Stars

A. Bulgac, M. Forbes, B. Haskell

Turbulence phenomena are characterized by cascades and inverse cascades of energy through different length scales. Quantum superfluids, despite being dissipationless, also exhibit turbulent phenomena which is typically characterized by the creation and dynamics of topological defects such as superfluid vortices and vortex rings. .

In the News

In this work, we have searched for the interaction of dark matter particles with pions in atomic nuclei, manifested as characteristic xenon nuclear recoils in the XENON1T data. Our analysis finds no evidence for a dark matter-pion interaction, but sets the first limit on its strength. Previous analyses only considered the interaction of dark matter with individual nucleons, but nucleons interact due to the strong nuclear force, which arises for example from the exchange of virtual pions. A putative dark matter particle could then scatter off these pions, an interaction we have constrained for the first time. Read more...

Zohreh Davoudi, a former INT and Nuclear Theory graduate student and currently an assistant professor of physics at the University of Maryland, has been awarded a 2019 Sloan Research Fellowship. Granted by the Alfred P. Sloan Foundation, this award identifies 126 early-career scientists every year based on their potential to contribute fundamentally significant research to the wider academic community. Read more...

The American Physical Society awarded its 2019 Lars Onsager Prize to Christopher Jarzynski, a former INT post-doctoral fellow and currently a Distinguished University Professor in the University of Maryland’s Department of Chemistry and Biochemistry, Department of Physics, and Institute for Physical Science and Technology (IPST). Jarzynski will receive the prize, which recognizes outstanding research in theoretical statistical physics, at the society’s March Meeting 2019 in Boston. Read more...

International Day of Women and Girls in Science - 2019.

A wonderful presentation by Professor Assumpta Parreno. Assumpta is the Deputy Director of the Institut de Ciencies del Cosmos at the Universitat de Barcelona in Spain, and early in her career was a Postdoctoral Fellow at the INT.

The US's plan for quantum computing and quantum information science. From the dynamics of non-equilibrium matter in the early universe to the structure of nuclei, QC and QIS may provide is expected to provide a quantum advantage over classical computation in the future.

2018 Nobel Prize in Physics

“For groundbreaking inventions in the field of laser physics” with one half to Arthur Ashkin “for the optical tweezers and their application to biological systems” and the other half jointly to Gérard Mourou and Donna Strickland “for their method of generating high-intensity, ultra-short optical pulses”. [Nobel website]

This particle tracker offers the first direct measurement, at the Relativistic Heavy Ion Collider (RHIC), of how charm quarks are caught up in the flow of a primordial quark-gluon ``plasma'' -- a liquid-like matter that mimics the conditions of the early universe moments after the Big Bang.
