ATLAS uses the Higgs boson as a tool to search for Dark Matter

One of the great unexplained mysteries is the nature of dark matter. So far, its existence has only been established through gravitational effects observed in space; no dark-matter particles with the needed properties have (yet) been detected. Could the Higgs boson be the key to their discovery?

Leptons at a distance: a new search for long-lived particles

ATLAS researchers are broadening their extensive search programme to look for more unusual signatures of unknown physics, such as long-lived particles. A theory that naturally motivates long-lived particles is supersymmetry (SUSY). A new search from the ATLAS Collaboration – released this week for the 5th International Conference on Particle Physics and Astrophysics (ICPPA-2020) – looks for the superpartners of the electron, muon and tau lepton

New ATLAS result marks milestone in the test of Standard Model properties

The ATLAS Collaboration has released a new study into a key building block of matter: leptons . This type of particle comes in three different families (flavours) and, according to the Standard Model, should follow strict rules. For instance, except for their mass, leptons of different flavours have identical properties – a feature known as lepton flavour universality. This was recently corroborated by a key measurement of the W-boson decay rates into leptons by the ATLAS Collaboration.

New measurements of the Higgs boson find strength in unity

Physicists can study Higgs-boson couplings in several ways: by measuring the rates of different Higgs boson production mechanisms and decays, and also by studying the particle’s kinematic properties. The ATLAS Collaboration has just presented precise new measurements of these key quantities. Several of these measurements were updated to use the full LHC Run 2 dataset (2015–2018), to provide the best precision to date.

Looking forward: ATLAS measures proton scattering when light turns into matter

Today, at the International Conference for High Energy Physics (ICHEP 2020), the ATLAS Collaboration announced first results using the ATLAS Forward Proton (AFP) spectrometer. With this instrument, physicists directly observed and measured the long sought-after prediction of proton scattering when particles of light turn into matter.

ATLAS probes interactions between heavyweights of the Standard Model

In the contest for the heaviest known elementary particle, the top quark and Z boson rank first and third, respectively. When a proton–proton collision produces a top-quark pair together with a Z boson – a process known as ttZ production – their total mass can reach an impressive 440 GeV! The discovery of this highly energetic process thus required the record collision energy and rate of the LHC; no previous collider could come close.

Jetting into the dark side: a precision search for dark matter

The nature of dark matter remains one of the great unsolved puzzles of fundamental physics. Many theoretical scenarios postulate that dark matter particles could be produced in the intense high-energy proton–proton collisions of the LHC. While the dark matter would escape the ATLAS detector unseen, it could occasionally be accompanied by a visible jet of particles radiated from the interaction point. Today, at the International Conference in High-Energy Physics (ICHEP 2020), ATLAS presented a new search for novel phenomena in collision events with jets and high missing transverse momentum (MET).

Introduction to the ATLAS Experiment

The atlas detector ​.

The ATLAS (A Toroidal LHC ApparatuS) detector is one of the two general-purpose detectors at the Large Hadron Collider (LHC). It is a key tool in high-energy physics because it provides comprehensive data on the vast amount of particles created in the LHC's high-energy collisions. Its array of sensors and instruments is designed to track and identify particles with great precision, enabling scientists to reconstruct and analyze the complex events resulting from these collisions. ATLAS plays a central role in the LHC's research by allowing physicists to test theoretical predictions in particle physics, including the existence of predicted but undiscovered particles, and to explore the fundamental forces and materials that shape our universe. Through this extensive data collection and analysis, ATLAS contributes significantly to our understanding of the Standard Model and the search for new physics beyond it.

Design and Components ​

ATLAS is a multi-purpose particle physics detector with a forward-backward symmetric cylindrical geometry and nearly 4π coverage in solid angle. It is one of the largest and most complex scientific instruments ever constructed, measuring about 44 meters in length and 25 meters in diameter. The detector consists of various layers, each designed to measure different properties of the particles that emerge from the LHC collisions:

  • Inner Tracker : Closest to the collision point, this high-precision tracker detects the paths of charged particles.
  • Calorimeters : Surrounding the tracker are the calorimeters. The Electromagnetic Calorimeter measures the energy of electrons and photons, while the Hadronic Calorimeter does the same for hadrons.
  • Muon Spectrometer : Encasing the calorimeters, the muon spectrometer tracks muons, particles similar to electrons but much heavier, using a system of large superconducting magnets and precision chambers.
  • Magnet Systems : The ATLAS detector utilizes a unique configuration of magnets, including the largest superconducting toroid magnets ever made, to bend the paths of charged particles for momentum measurement.

ATLAS experiment configuration

ATLAS is designed to detect a wide range of particle interactions. Its various components work together to provide comprehensive data about the particles produced in LHC collisions, including their trajectories, momenta, energy, and other identifying characteristics. This information is used for identifying and studying the properties of new and known particles, testing the predictions of the Standard Model, and searching for new physics beyond it.

The Collaboration ​

The ATLAS collaboration is proof of the effectiveness of global scientific partnership. Comprising over 3,000 scientific authors from 42 countries and 182 institutions, the success of ATLAS relies on the close collaboration of research teams located at CERN, and at member universities and laboratories worldwide.

The organizational structure of ATLAS is designed to foster autonomy and collaborative synergy, allowing individual researchers and groups to focus on areas of personal scientific interest while contributing to the collective goals of the experiment. This balance of individual initiative and shared work is important for innovation within the project's framework.

Financially, the collaboration is underpinned by contributions from international funding agencies, CERN, and university investments, reflecting the shared global commitment to advancing scientific knowledge.

The leadership within ATLAS is democratically elected, ensuring that decision-making reflects the collaboration's diverse perspectives and expertise. This inclusive approach extends to the management of the detector's subsystems, with each team's creative input shaping the project's success.

The collaborative nature of ATLAS means that the data generated is a product of significant investment, both in terms of finance and human capital. The decision to keep data within the collaboration for a period before public release is a reflection of this investment and the need to ensure that those who have contributed have the opportunity to analyze and publish their findings.

The ATLAS collaboration operates on principles of shared knowledge, democratic governance, and equitable contribution, which are all key in achieving the scientific objectives while guaranteeing fair recognition and utilization of the resources provided by its international partners.

Rare phenomenon observed by atlas features the lhc as a high-energy photon collider.

During the International Conference on High-Energy Physics (ICHEP 2020), the ATLAS Collaboration presented the first observation of photon collisions producing pairs of W bosons, elementary particles that carry the weak force, one of the four fundamental forces. The result demonstrates a new way of using the LHC, namely as a high-energy photon collider directly probing electroweak interactions. It confirms one of the main predictions of electroweak theory – that force carriers can interact with themselves – and provides new ways to probe it.
