The High Energy and Particle Physics Division of the EPS is happy to announce the 2021 EPS HEPP prizes.

The 2021 EPS High Energy and Particle Physics prize is awarded to Torbjörn Sjöstrand and Bryan Webber for the conception, development and realisation of parton shower Monte Carlo simulations, yielding an accurate description of particle collisions in terms of quantum chromodynamics and electroweak interactions, and thereby enabling the experimental validation of the Standard Model, particle discoveries and searches for new physics.

The 2021 Giuseppe and Vanna Cocconi Prize is awarded to the Borexino Collaboration for their ground-breaking observation of solar neutrinos from the pp chain and CNO cycle that provided unique and comprehensive tests of the Sun as a nuclear fusion engine.

The 2021 Gribov Medal is awarded to Bernhard Mistlberger for his groundbreaking contributions to multi-loop computations in QCD and to high-precision predictions of Higgs and vector boson production at hadron colliders.

The 2021 Young Experimental Physicist Prize of the High Energy and Particle Physics Division of the EPS is awarded to Nathan Jurik for his outstanding contributions to the LHCb experiment, including the discovery of pentaquarks, and the measurements of CP violation and mixing in the B and D meson systems; and to Ben Nachman for exceptional contributions to the study of QCD jets as a probe of QCD dynamics and as a tool for new physics searches, his innovative application of machine learning for characterising jets, and the development of novel strategies on jet reconstruction and calibration at the ATLAS experiment.

The 2021 Outreach Prize of the High Energy and Particle Physics Division of the EPS is awarded to Uta Bilow and Kenneth Cecire for the long-term coordination and major expansion of the International Particle Physics Master Classes to include a range of modern methods and exercises, and connecting scientists from all the major LHC and Fermilab experiments to school pupils across the world; and to Sascha Mehlhase for the design and creation of the ATLAS detector and other interlocking-brick models, creating an international outreach program that reaches to an unusually young audience.

All prizes will be awarded in a ceremony on July 26, 2021 during the virtual EPS-HEP 2021 conference: https://www.eps-hep2021.eu/
