Mission

The INT was founded in 1990, and has as its mission statement:

• To create a research environment where visiting scientists can focus their energies on key frontier areas of the field, including those crucial to the success of existing and future experimental facilities.
• To encourage interdisciplinary research at the intersections of nuclear physics with related disciplines, such as particle physics, astrophysics, atomic physics, and condensed matter physics. The goals are to build greater appreciation, in the general physics community, for the tools of nuclear physics and the breadth of their possible applications, and to assure that new ideas generated in other fields are quickly assimilated and exploited by nuclear physics.
• To recruit and nurture the best young researchers, thereby enhancing their professional prospects. The goal is to ensure a highly trained and talented pool of nuclear scientists to meet the nation's needs.
• To contribute to scientific education through graduate student research, INT summer schools, and co-sponsorship of national schools and workshops.
• To strengthen international cooperation in nuclear physics and physics generally, through cooperative programs and exchanges.
• We view the running of visitor programs to be the core of the INT, all INT programs being community driven and prioritized by the NAC. INT program and workshop attendance has reached a steady state, with the INT hosting roughly 400 scientific visitors per year.

INT Budget History

The INT is funded annually from June 1 of each year; the grant is normally on a 5-year cycle, with the current budget being Year 1 of the 5-year grant running from June 1, 2024 to May 31, 2029. Historically from 2000-2024, the INT had been on a growth trajectory for annual funding increases of 2-3% each year.

 

Cost of Programs and Workshops

The INT support visitors’ local expenses, which is roughly ~80% of lodging costs (which varies based on season and lodging selected) and $30 meal per diem. Travel expenses are not provided unless there is an exception approved by the event organizers and INT Director. We can host up to 20 participants (limited by desk space) per week during INT programs and 45 participants at INT workshops (limited by the seating capability of our meeting room). Our goal is to ensure a 16-person average attendance during programs and a 40-person average attendance for workshops.

Research Impact of INT Programs and Workshops

It is hard to fully assess the long-term impact of research activity at the INT until years later, but here is a sample of accomplishments that can be traced back to the INT:

• Generalized Parton Distributions (GDPs) were invented at the 1996 INT program "Quark and Gluon Structure of Nucleons and Nuclei"; X. Ji's (Maryland) two papers have now accrued over 1700 citations.
• INT post-doc Chris Jarzynski (post-doc 1994-1996) developed his theory of microscopic work leading to his being awarded the Sackler prize in 2008 for his "ground breaking developments in statistical mechanics".
• The first modeling of neutrino-nucleus inelastic interactions important to core-collapse supernovae was done at the INT, leading to the recognition of a new mechanism for supernova nucleosynthesis, the neutrino process.
• The development of effective field theory for nuclear physics occurred at two INT workshops held in 1998 and 1999. The seminal papers from these meetings have been very influential in low-energy few-body physics, developing more realistic nucleon potentials and extracting useful data from lattice simulations.
• Much of the early phenomenology of the Colored Glass Condensate (CGC) for RHIC collisions was developed at the INT, including the prediction of particle suppression at forward rapidity, which was subsequently verified experimentally and remains the strongest evidence for CGC.
• The current focus of the nuclear structure community on mean field theory and the energy density functional can be traced back to programs at the INT ("Nuclear Structure near the Limits of Stability, Fall 2005") and the leadership of Senior Fellow Bertsch.
• The AdS/CFT correspondence has been used to compute jet quenching and other features of quark-gluon plasmas. This effort was spearheaded by participants of the 2003 INT program "QCD and String Theory.” Son's viscosity bound has proved to be a key development in the hydrodynamic theory of heavy ion collisions, and the role of viscosity now dominates the research of the hydro community today.
• INT post-doc Shina Tan (post-doc 2006-2008) developed his theory of universal properties of many-body wave functions (the so-called "Tan Relations") leading to his receiving the 2010 APS George E Valley Prize, given biennially to the one physicist within five years of PhD deemed to have made the most significant contribution to physics.
• The 2010 program on EIC physics led to the publication of a thick volume, underwritten by the INT, outlining the possible scientific program for such a facility.
• The 2017 program on “Electromagnetic Signatures of R-process Nucleosynthesis in Neutron Star Mergers” and the 2014 program “Binary Neutron Star Coalescence as a Fundamental Physics Laboratory” played a key role in presciently bringing together the nuclear physics, astrophysics, and gravitational wave communities before GW170817- the first multi-messenger observation of a neutron star merger.
• The 2017 INT program on “Neutrinoless Double-beta Decay” and  the workshop on  “Lattice QCD inputs for Neutrinoless Double-beta Decay” have catalyzed theoretical developments in effective field theory, ab-initio nuclear structure, and lattice QCD that have paved the way for modern calculations of the decay half-lives, with better control on  theoretical uncertainties.  
• The program “Probing Nucleons and Nuclei in High Energy Collisions,” which was held at the Institute for Nuclear Theory, Seattle, WA, USA, from October 1 until November 16, 2018, resulted in the publication of a 332-page collection of proceedings. These proceedings are important for the experimental program at CERN and at BNL, 2002.12333 [hep-ph].
• The INT program on “Nuclear Structure at the Crossroads” held in 2019 brought together experts in nuclear interactions and nuclear many-body techniques that have been advancing nuclear structure calculations up to mass numbers A≃100 to address open issues. This field is at a critical point in its development, and this program played an important role in identifying priorities and led to a white paper, 2107.00413 [hep-ph].
• The 2019 INT workshop “Hadronic contributions to (g−2)μ ”, featuring 61 participants, brought together the Muon g−2 Theory Initiative and led to a community consensus for the entire Standard-Model prediction. This has led to the white paper “The anomalous magnetic moment of the muon in the Standard Model” 2006.04822 [hep-ph]. It has been widely used as a theory benchmark, including in the publications by the Fermilab experiment 2104.03281, 2308.06230, and has garnered more than 1000 citations.
• The 2020 INT workshop on “Origin of the Visible Universe: Unraveling the Proton Mass” addressed how the mass of the proton emerges from the strong interaction dynamics. The goal of the workshop was to identify key measurements to access and disentangle the individual contributions to the proton mass. Highlights from recent measurements at JLab of the gluonic trace anomaly were presented for the first time, and perspectives for future measurements at EIC were discussed.
• The INT workshop on “Machine Learning for Nuclear Theory” held in 2022 brought together researchers driving the development of machine learning and artificial intelligence for problems in nuclear theory and related areas. Applications discussed ranged from lattice QCD and statistical systems, hadron and nuclear structure, many-body theory, quantum computing, and nuclear astrophysics. Discussions initiated new collaborations and the exchange of techniques across different subfields.
• The 2022 INT workshop on “Dense Nuclear Matter Equation of State from Heavy-Ion Collisions” brought together and strengthened ties between subfields of nuclear physics interested in the Equation of State (EOS). As a result of the workshop, a white paper 2301.13253 has been written that highlights the role that heavy-ion collision experiments and simulations used to describe them can play, along with microscopic calculations and astrophysical observations, in constraining the EOS.

The INT's Post-Doc and 5-Year Fellow Program

A major goal of the INT is to mentor young scientists and help them attain tenure track or permanent research scientist positions after leaving the INT. Since its inception, the INT has historically supported five junior researchers at any given time: two Fellows and three postdoctoral research associates. In recent years due to fluctuations in DOE funding and receipt of funding from other sources, the number of postdoctoral fellows associated with the INT has varied in step with the available funds. Our DOE grant currently supports 6.5 postdoctoral fellows and one 5-yr Fellow that holds the rank of Research Assistant Professor in the Physics Department. In the fall, we will support 4 postdocs and two 5-yr Fellows.

The best metric for the INT’s success at mentoring young scientists is the number of former INT post-docs and Fellows now in permanent or tenure-track positions. Since the inception of the INT, 50 of the INT’s junior researchers have already found such positions.
