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.
Proton beams with giga-electron-volt (GeV) energies—once thought to be achievable only with massive particle accelerators—may soon be generated in compact setups thanks to a breakthrough by researchers at The University ...

The detection of dark matter, the elusive type of matter predicted to make up most of the universe's mass, is a long-standing goal in the field of astrophysics. As dark matter does not emit, reflect or absorb light, it cannot ...
Neutrinos are among the most enigmatic particles in the universe. They are omnipresent yet interact extremely rarely with matter.

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the view that the scientific ...
