Andreas Papaefstathiou's research will help elevate the study of particle physics in nuclear collisions at Kennesaw State University. The grant will also contribute to the development of a new particle collider in the US, strengthening partnerships between universities.
Scientists from the University of Kansas developed a technique to track ultra-peripheral collisions between protons and ions, resulting in the creation of gold momentarily. The discovery was made possible by studying photon-photon collisions, which are incredibly clean events with almost nothing else produced.
Physicists have shown that particles produced in 'jets' retain information about their origins in subatomic particle smashups. The study establishes a direct connection between the 'entanglement entropy' at the earliest stage of jet formation and the particles that emerge as a jet evolves.
A team of researchers from Chiba University successfully measured the interaction rates of high-energy electron and muon neutrinos using the FASERν detector at the Large Hadron Collider. The study marked the first direct observation of these interactions at a particle collider, providing new insights into particle physics.
Theoretical studies predict the existence of a new family of exotic subatomic particles called beautiful-charming tetraquarks. These particles are composed of four quarks, including two beauty and charm quarks, and two light anti-quarks. The prediction arrives at a fortuitous moment, coinciding with recent discoveries in this domain.
Researchers have made the first-ever observations of how lambda particles, a form of strange matter, are produced by a specific process called semi-inclusive deep inelastic scattering (SIDIS). The study reveals that diquarks, pairs of quarks and gluons, can march through atomic nuclei, contributing to the formation of lambdas.
Researchers from Japan propose a novel framework to describe quark-gluon plasma, which agrees better with experimental data. The new model explains the missing particle yields in low transverse momentum region by accounting for nonequilibrium corona components.
Scientists successfully synthesized the elusive Λ(1405) particle and measured its complex mass, revealing a temporary bound state of a K- meson and proton. The findings may provide insights into the interior of ultra-dense neutron stars and the early formation of the Universe.
Scientists study flow patterns from heavy-ion collisions to understand fluctuations in particle behavior, aiming to calculate the properties of quark-gluon plasma. The results point to initial state influences as the primary trigger for these fluctuations, with collision energy and nucleus size also playing a role.
Scientists at Brookhaven Lab will develop a comprehensive theoretical framework for describing the interaction of heavy-flavor particles with quark-gluon plasma. The Heavy-Flavor Theory Collaboration aims to provide insights into the properties of quark-gluon plasma and its precursors in nuclear matter.
A team of researchers from CERN, MIT, and Staffordshire University have developed a novel algorithm for reconstructing particles at the Large Hadron Collider. The project aims to improve particle reconstruction in high-occupancy imaging calorimeters, enabling more efficient discoveries after the HL-LHC upgrade.
Recent CERN experiments provide evidence for the existence of new particles called pentaquarks, which consist of four quarks and one antiquark. The discovery raises the possibility that a whole new class of matter is at the cusp of being discovered.
A team of scientists led by Clemson University's Marco Ajello has provided conclusive evidence that astrophysical neutrinos come from blazars, which are powerful black holes. This breakthrough resolves the long-standing question about the origin of high-energy cosmic rays.
The 2021 Fall Meeting of the APS Division of Nuclear Physics presents cutting-edge research on nuclear astrophysics, quantum technology, and rare isotopes. Researchers will discuss breakthroughs such as the most precise measurement of neutron lifetime and novel experiments measuring neutron skin in calcium.
Researchers recreated Quark-Gluon Plasma using Large Hadron Collider and analyzed its collective expansion. The study found that the plasma evolved from a fluent liquid form to a more solid state, changing its shape over time, which is surprising and different from other matters.
The American Physical Society has selected five researchers affiliated with Jefferson Lab as its 2020 Fellows. The winners include two staff scientists and three others who have conducted or collaborated on research at the lab. Their work has furthered our understanding of the subatomic world.
Quark and gluon researcher Nobuo Sato aims to bridge the gap between theory and experiment to understand how these particles form hadrons, which make up protons, neutrons, and other atomic particles. His three-year fellowship will allow him to pursue independent research at Jefferson Lab.
Andrea Signori's project, 'Unraveling Hadronization,' aims to improve fragmentation functions and make them more accurate. This will give physicists more confidence in detecting specific quarks in particles, leading to a better understanding of hadronization.
Researchers at Far Eastern Federal University are studying the properties of quark-gluon plasma using a combination of lattice quantum chromodynamics and neural networks. The goal is to understand how this substance modifies with temperature and density changes.
Young scientists Anne-Marie Valente-Feliciano, Anselm Vossen, and Raul Briceño receive grants to support their research on building better accelerators and studying subatomic particle interactions. They will utilize Jefferson Lab's upgraded accelerator and supercomputers to advance our understanding of particle physics.
