Particle phenomena, as a research area, encompasses the theoretical and experimental investigation of processes, interactions, and emergent behaviors involving elementary and composite particles, primarily within high-energy and nuclear physics. It focuses on quantifying scattering amplitudes, decay channels, production cross-sections, and correlation patterns governed by the Standard Model and its proposed extensions. Research in particle phenomena typically addresses gauge interactions, symmetry breaking, confinement, hadronization, and collective effects in many-body systems such as quark–gluon plasma. The field integrates accelerator-based experiments, detector technology, and advanced computational methods to test fundamental symmetries, probe new physics scales, and refine effective field theories describing particle interactions.
Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most past experiments have focused on heavier dark matter candidates, while much lighter dark matter, ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using conventional technologies used by ...
The origins of extremely high-energy particles that fill the universe—such as protons, electrons, and neutrinos—remain one of the longest-standing mysteries in modern astrophysics. A leading hypothesis suggests that "explosive ...
