News and Announcements

In 2021 the Isaac Pomeranchuk Prize is awarded to Professor Larry McLerran (the Institute for Nuclear Theory at the University of Washington Seattle, USA) in recognition of his pioneering contributions to modern understanding of quantum chromodynamics at high energy density and laying the theoretical foundations of ultra-relativistic heavy ion collisions and Prof. Aleksei Starobinskiy (Landau Institute, Chernogolovka) for his research in the field of gravitation and cosmology, including the development of the theory of the inflationary stage in the early Universe.

Jens Gundlach, Eric Adelberger, and Blayne Heckel are Co-Winners of the 2021 Breakthrough Prize in Fundamental Physics for their work on Tabletop Gravity experiments.

Theoretical physicist Gordon Baym, Professor Emeritus at the University of Illinois at Urbana-Champaign, will receive the 2021 American Physical Society (APS) Medal for Exceptional Achievement in Research. Baym will be recognized for his seminal contributions to several fields of physics in early 2021.

In this and a companion paper, Phys. Rev. D 49, 3352 (1994), Larry McLerran and Raju Venugopalan proposed a classical model for the scattering of large nuclei at high energies. They argued that the color charges of the valence quarks can be treated as static sources which propagate along the light cone. A high density of soft gluons is generated, and can be described as a classical gauge field. This provides an energy scale much larger than the usual QCD scale, and so a small QCD coupling.

The Muon g-2 Theory Initiative released an extensive review of the Standard Model prediction for the anomalous magnetic moment of the muon. This community-wide consensus was developed in a series of workshops over the last 3 years, the latest hosted by the INT in September 2019, involving key discussions that led to the recommendations in the white paper. The final value differs from the Brookhaven measurement by 3.7 standard deviations and sets the benchmark for the highly anticipated results from the Fermilab E989 experiment.
