particulele

Particulele is the Romanian word for “the particles,” the definite plural form of particulă. In scientific usage, particulele refers to small, discrete constituents of matter or radiation that can be described by physics and chemistry. The term is common in Romanian textbooks and articles when discussing microscopic objects from molecules to subatomic particles.

In physics, particles can be classified as elementary or composite. Elementary particles include quarks, leptons (such as electrons and neutrinos), gauge bosons (photons, gluons, W and Z bosons), and the Higgs boson. Composite particles include protons, neutrons, mesons, and atoms. Particulele are characterized by properties such as mass or energy, electric charge, and spin, as well as quantum numbers like flavor and, for quarks and gluons, color charge. Their behavior is governed by the laws of quantum mechanics and quantum field theory, with the Standard Model providing a framework for their interactions via the electromagnetic, weak, and strong forces (gravity being described separately in general relativity).

The study of particulele is central to particle physics. Experimental investigations use particle accelerators and detectors to observe collision outcomes, measure lifetimes and masses, and identify decay channels. Milestones include the discovery of the Higgs boson in 2012 at the Large Hadron Collider and evidence for neutrino oscillations, which showed that neutrinos have mass. In Romanian scientific writing, particulele also appear in broader contexts, such as environmental science, where they can refer to fine particles in air or water when specified.
