The Tevatron was a circular particle accelerator in the United States, at the Fermi National Accelerator Laboratory, east of Batavia, Illinois, and is the second highest energy particle collider ever built, after the Large Hadron Collider (LHC) of the European Organization for Nuclear Research (CERN) near Geneva, Switzerland. The Tevatron was a synchrotron that accelerated protons and antiprotons in a 6.28 km (3.90 mi) ring to energies of up to 1 TeV, hence its name. The Tevatron was completed in 1983 at a cost of $120 million and significant upgrade investments were made during its active years of 1983–2011.
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories across more than 100 countries. It lies in a tunnel 27 kilometres (17 mi) in circumference and as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.
ATLAS is the largest general-purpose particle detector experiment at the Large Hadron Collider (LHC), a particle accelerator at CERN in Switzerland. The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators. ATLAS was one of the two LHC experiments involved in the discovery of the Higgs boson in July 2012. It was also designed to search for evidence of theories of particle physics beyond the Standard Model.
H1 was a particle detector operated at the HERA collider at the German national laboratory DESY in Hamburg. The first studies for the H1 experiment were proposed in 1981. The H1 detector began operating together with HERA in 1992 and took data until 2007. It consisted of several different detector components, measured about 12 m × 15 m × 10 m and weighed 2800 tons. It was one of four detectors along the HERA accelerator.
The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed. It was built at CERN, a multi-national centre for research in nuclear and particle physics near Geneva, Switzerland.
The Collider Detector at Fermilab (CDF) experimental collaboration studies high energy particle collisions from the Tevatron, the world's former highest-energy particle accelerator. The goal is to discover the identity and properties of the particles that make up the universe and to understand the forces and interactions between those particles.
The DØ experiment was a worldwide collaboration of scientists conducting research on the fundamental nature of matter. DØ was one of two major experiments located at the Tevatron Collider at Fermilab in Batavia, Illinois. The Tevatron was the world's highest-energy accelerator from 1983 until 2009, when its energy was surpassed by the Large Hadron Collider. The DØ experiment stopped taking data in 2011, when the Tevatron shut down, but data analysis is still ongoing. The DØ detector is preserved in Fermilab's DØ Assembly Building as part of a historical exhibit for public tours.
The High Luminosity Large Hadron Collider is an upgrade to the Large Hadron Collider, operated by the European Organization for Nuclear Research (CERN), located at the French-Swiss border near Geneva. From 2011 to 2020, the project was led by Lucio Rossi. In 2020, the lead role was taken up by Oliver Brüning.
The LHCf is a special-purpose Large Hadron Collider experiment for astroparticle physics, and one of nine detectors in the LHC accelerator at CERN. LHCf is designed to study the particles generated in the forward region of collisions, those almost directly in line with the colliding proton beams.
QuarkNet is a long-term, research-based teacher professional development program in the United States jointly funded by the National Science Foundation and the US Department of Energy. Since 1999, QuarkNet has established centers at universities and national laboratories conducting research in particle physics across the United States, and have been bringing such physics to high school classrooms. QuarkNet programs are designed and conducted according to “best practices” described in the National Research Council National Science Education Standards report (1995) and support the Next Generation Science Standards (2013).
The search for the Higgs boson was a 40-year effort by physicists to prove the existence or non-existence of the Higgs boson, first theorised in the 1960s. The Higgs boson was the last unobserved fundamental particle in the Standard Model of particle physics, and its discovery was described as being the "ultimate verification" of the Standard Model. In March 2013, the Higgs boson was officially confirmed to exist.
David George Charlton is Professor of Particle Physics in the School of Physics and Astronomy at the University of Birmingham, UK. From 2013 to 2017, he served as Spokesperson of the ATLAS experiment at the Large Hadron Collider at CERN. Prior to becoming Spokesperson, he was Deputy Spokesperson for four years, and before that Physics Coordinator of ATLAS in the run-up to the start of collision data-taking.
Sir Tejinder Singh Virdee,, is a Kenyan-born British experimental particle physicist and Professor of Physics at Imperial College London. He is best known for originating the concept of the Compact Muon Solenoid (CMS) with a few other colleagues and has been referred to as one of the 'founding fathers' of the project. CMS is a world-wide collaboration which started in 1991 and now has over 3500 participants from 45 countries.
Peter Jenni, is an experimental particle physicist working at CERN. He is best known as one of the "founding fathers" of the ATLAS experiment at the CERN Large Hadron Collider together with a few other colleagues. He acted as spokesperson of the ATLAS Collaboration until 2009. ATLAS is a world-wide collaboration which started in 1992 involving roughly 3,000 physicists at 183 institutions in 38 countries. Jenni was directly involved in the experimental work leading to the discoveries of the W and Z bosons in the 1980s and the Higgs boson in 2012. He is (co-)author of about 1000 publications in scientific journals.
Ashutosh Vijay Kotwal is an American particle physicist of Indian origin. He is the Fritz London Professor of Physics at Duke University, and conducts research in particle physics related to W bosons and the Higgs boson and searches for new particles and forces.
Stephanie A. Majewski is an American physicist at the University of Oregon (UO) researching high energy particle physics at the CERN ATLAS experiment. She worked as a postdoctoral research associate at the Brookhaven National Laboratory prior to joining the faculty at UO in 2012. She was selected for the Early Career Research Program award of the U.S. Department of Energy (DOE), one of 35 scientists in all DOE-supported fields to receive this national honor in 2014.
FASER is one of the nine particle physics experiments in 2022 at the Large Hadron Collider at CERN. It is designed to both search for new light and weakly coupled elementary particles, and to detect and study the interactions of high-energy collider neutrinos. In 2023, FASER and SND@LHC reported the first observation of collider neutrinos.
