Weakly interacting massive particles (WIMPs) are hypothetical particles that are one of the proposed candidates for dark matter.
The Compact Muon Solenoid (CMS) experiment is one of two large general-purpose particle physics detectors built on the Large Hadron Collider (LHC) at CERN in Switzerland and France. The goal of CMS experiment is to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.
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, as well as 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.
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.
LHC@home is a distributed computing project for particle physics based on the Berkeley Open Infrastructure for Network Computing (BOINC) platform. The project's computing power is utilized by physicists at CERN in support of the Large Hadron Collider and other experimental particle accelerators.
The LHCb experiment is one of eight particle physics detector experiments collecting data at the Large Hadron Collider at CERN. LHCb is a specialized b-physics experiment, designed primarily to measure the parameters of CP violation in the interactions of b-hadrons. Such studies can help to explain the matter-antimatter asymmetry of the Universe. The detector is also able to perform measurements of production cross sections, exotic hadron spectroscopy, charm physics and electroweak physics in the forward region. The LHCb collaboration, who built, operate and analyse data from the experiment, is composed of approximately 1260 people from 74 scientific institutes, representing 16 countries. Chris Parkes succeeded on July 1, 2020 as spokesperson for the collaboration to Giovanni Passaleva. The experiment is located at point 8 on the LHC tunnel close to Ferney-Voltaire, France just over the border from Geneva. The (small) MoEDAL experiment shares the same cavern.
ALICE is one of eight detector experiments at the Large Hadron Collider at CERN. The other seven are: ATLAS, CMS, TOTEM, LHCb, LHCf, MoEDAL and FASER.
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 Higgs boson, sometimes called the Higgs particle, is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory. The Higgs boson is named after Peter Higgs. In the Standard Model, the Higgs particle is a massive scalar boson with zero spin, even (positive) parity, no electric charge, and no colour charge, that couples to mass. It is also very unstable, decaying into other particles almost immediately.
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.
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.
The Future Circular Collider (FCC) is a proposed post-LHC particle accelerator with an energy significantly above that of previous circular colliders. The FCC project examines scenarios for three different types of particle collisions: hadron collisions in a collider design known as FCC-hh, electron–positron collisions in a collider design known as FCC-ee, and proton–electron collisions in a collider design known as FCC-eh.

FASER is planned to be one of the eight 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 study the interactions of high-energy neutrinos.
Oliver Buchmueller is a scientist and professor of physics at the Faculty of Natural Science, Imperial College London. Buchmueller is presently serving as one of the lead scientists on the CMS experiment at CERN’s LHC, the Principal Investigator of the Atom Interferometer Observatory and Network (AION) and also one of the lead authors at Atomic Experiment for Dark Matter and Gravity Exploration in Space (AEDGE). Previously he has been associated with ALPEH experiment at CERN’s LEP collider and the BaBar experiment at SLAC. Buchmueller was among the group of scientists responsible for the discovery of Higgs Boson particle at the LHC, CERN and later in the scientific exploration to find the traces of dark matter through the LHC.
The Scattering and Neutrino Detetcor (SND) at Large Hadron Collider (LHC), CERN, is currently being built for the detection of the collider neutrinos. The primary goal of SND is to measure the p+p --> +X process and search for the feebly interacting particles. It will be operational from 2022, during the LHC-Run 3 (2022-2024). SND will be installed in an empty tunnel- TI18 that links the LHC and Super Proton Synchrotron, 480m away from the ATLAS experiment interaction point in the fast forward region and along the beam collision axis.
Ritchie Patterson is a physicist at Cornell University known for her research using the Large Hadron Collider to examine dark matter and the disappearance of antimatter. She is a fellow of the American Physical Society and an elected member of the American Association for the Advancement of Science.
The MilliQan experiment is a small-scale detector experiment at CERN's Large Hadron Collider (LHC). The goal of the MilliQan experiment is to detect millicharged particles: particles with charges much smaller than that of the electron. These particles are motivated by the existence of a dark photon, and discovery of millicharged particles would provide a first probe into the dark sector. The MilliQan prototype detector collected data during LHC Run 2 in 2018 and set competitive constraints on millicharged particle charges and masses. The upgraded Run 3 MilliQan detectors are scheduled to be installed in 2022
