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.
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013.
The LHCb collaboration recently reported on the arXiv preprint server the first observation of the decay of the Bc+ meson (composed of two heavy quarks, b and c) into a J/ψ charm-anticharm quark bound state and a pair of ...
