Particle physics is a research area focused on the fundamental constituents of matter and radiation and the interactions governing them, typically described by quantum field theories such as the Standard Model. It investigates quarks, leptons, gauge bosons, and the Higgs boson, and their dynamics under the strong, weak, and electromagnetic forces, often at high energies where new degrees of freedom become accessible. The field relies on large-scale experiments (e.g., collider-based and fixed-target facilities), precision measurements, and advanced detectors, while also exploring physics beyond the Standard Model, including neutrino properties, dark matter candidates, and potential new symmetries or interaction sectors.
With the help of innovative large-scale simulations on various supercomputers, physicists at Johannes Gutenberg University Mainz (JGU) have succeeded in gaining new insights into previously elusive aspects of the physics ...

Baryons, composite particles made up of three quarks bound together via the so-called strong force, make up the most visible matter and have thus been the focus of numerous physics studies. Studying the rare processes via ...
Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What is the particle nature ...

In a breakthrough for antimatter research, the BASE collaboration at CERN has kept an antiproton—the antimatter counterpart of a proton—oscillating smoothly between two different quantum states for almost a minute while trapped. ...

A rather unassuming particle is playing an important role in the hunt for subatomic oddities. Similar to protons and neutrons, mesons are composed of quarks bound together by the strong nuclear force. But these short-lived ...

Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their observed oscillations suggest that they do in fact have a mass, which is very low. A further characteristic ...
In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, the strong nuclear force, ...
