Welcome to the Institute for Nuclear Theory (INT)

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.

January 25 - February 5, 2027

Prospects for Fundamental Investigations with Ultracold Neutrons

T. Chupp, T. Ito, E. Mereghetti, P. Mumm, A. Saunders, C.-Y. Seng, A. Young

This two-week program of talks and discussions will focus on assessing the new physics discovery potential and model diagnosing power of new UCN sources, experimental opportunities, and the role of SM and BSM theory over 10-, 20-, and 30-year time frames.

February 22 - 26, 2027

Exploring New Approaches to Neutrino Flavor Transport

H. Duan, S. Richers, I.Tamborra

Because of the large disparity between the scales of neutrino oscillations and hydrodynamics, neutrino flavor mixing has only recently begun to be implemented in simulations of core-collapse supernovae (CCSNe) and neutron star mergers (NSMs), and even then only through approximate approaches.

Chiral Gauge Theories on the Lattice and Beyond

A. Cherman, S. Sen, H. Singh

This program aims to bring together researchers from high-energy physics, lattice field theory, condensed matter physics, quantum information, and tensor networks to address one of the central open problems in theoretical physics: the nonperturbative formulation and simulation of chiral gauge theories.

March 22 - April 2, 2027

Towards Realizing the Program with Polarized Ion Beams at EIC

R. Milner, Z.E. Meziani, P. Shanahan, F. Rathmann

In March 2025, the EIC Polarized Ion Source (EPIOS) scientific consortium was formed. EPIOS has written a whitepaper published in June 2026 as a Perspective in Physical Review C where the science case is summarized.

INTURN

Institute for Nuclear Theory Undergraduate Research Network

The Institute for Nuclear Theory (INT) at the University of Washington (UW) offers opportunities for undergraduate research in nuclear physics. This INT Undergraduate Research Network (INTURN) program hosts undergraduate students interested in pursuing research in nuclear theory and taking steps toward a career in physics.
