Particle detectors, as a technique, encompass the ensemble of methods and instrumentation used to register, localize, and characterize ionizing particles through their interactions with matter. These techniques exploit processes such as ionization, scintillation, Cherenkov radiation, and semiconductor charge collection to convert particle passage into measurable electrical or optical signals. Detector techniques include tracking (e.g., gaseous wire chambers, silicon strip and pixel detectors), calorimetry (sampling and homogeneous calorimeters for energy measurement), and time-of-flight methods for velocity determination, often integrated in complex, layered systems enabling precise reconstruction of particle trajectories, momenta, identities, and interaction vertices in nuclear, particle, and astroparticle physics experiments.

The Belle II experiment is a large research effort aimed at precisely measuring weak-interaction parameters, studying exotic hadrons (i.e., a class of subatomic particles) and searching for new physical phenomena. This effort ...
The Higgs boson was discovered in the detectors of the Large Hadron Collider a dozen or so years ago. It has proved to be a particle so difficult to produce and observe that, despite the passage of time, its properties are ...
