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.
It has been over a century since the boom period of physics exploded with Albert Einstein, Max Planck and others, sending us spinning into a new world of chaos from our previously ordered universe. This brilliant generation ...

A large international team of physicists working on the BES III collaboration has announced possible physical evidence of glueballs. In their study, published in the journal Physical Review Letters, the group analyzed decaying ...
Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical theory. This description sets ...
