PROSPECT Characterizes the Footprint of Neutrinos
Predictions based on the Standard Model of particle physics don’t always agree with what scientists see in experimental data. One way to examine these differences is emissions of neutrinos from nuclear reactors. As part of this research agenda, scientists in the PROSPECT Collaboration have reported the most precise measurement ever of the energy spectrum of antineutrinos emitted from the fission of uranium-235, providing a new reference energy spectrum and new constraints on the origin of the disagreements between data and models.

Why the day is 24 hours long: Astrophysicists reveal why Earth’s day was a constant 19.5 hours for over a billion years
A team of astrophysicists at the University of Toronto (U of T) has revealed how the slow and steady lengthening of Earth’s day caused by the tidal pull of the moon was halted for over a billion years.
University of Minnesota theoretical physicists help expand the search for new particle
A team led by University of Minnesota Twin Cities physicists has discovered a new way to search for axions, hypothetical particles that could help solve some of nature’s most puzzling mysteries.
SLAC theorist Lance Dixon receives Galileo Galilei Medal
Lance Dixon, professor of particle physics and astrophysics at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University, will receive the 2023 Galileo Galilei Medal for his contributions to theoretical physics. The award was announced by the Italian National Institute of Nuclear Physics (INFN) on Feb. 15 – the 459th birthday of Galileo.
‘Exotic hadrons’ research to advance knowledge of nuclear physics
IU physicist Adam Szczepaniak is leading a project exploring the physics of exotic hadrons — a largely unexplored group of subatomic particles — under a $1.8 million grant from the U.S. Department of Energy.
Confining quarks
A new way to study quarks, one of the building blocks of the protons and neutrons that make up atomic nuclei, is proposed.
Particles of Light May Create Fluid Flow, Data-Theory Comparison Suggests
A new computational analysis by theorists at Brookhaven National Laboratory and Wayne State University supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can create a fluid of “strongly interacting” particles. In a new paper they show that calculations describing such a system match up with data collected by the ATLAS detector at Europe’s Large Hadron Collider (LHC).
Researchers build long-sought nanoparticle structure, opening door to special properties
Researchers have built a unique, long-sought structure from gold nanoparticles. Alex Travesset of Iowa State and the Ames National Laboratory has the equations and illustrations to explain how it all happened. This new nanomaterial could have useful optical, mechanical and electronic characteristics.
Theoretical calculations predicted now-confirmed tetraneutron, an exotic state of matter
Iowa State University’s James Vary and an international team of nuclear physicists used supercomputers to theorize and predict that a four-neutron structure, a tetraneutron, could form for just billions of billionths of a second. Experiments in Japan have now confirmed the reality of a tetraneutron.
Research Breakthrough Means Warp Speed ‘Unruh Effect’ Can Finally Be Tested in Lab Settings
