👉 National Light Particles, often referred to as LEP (Large Electron-Positron) particles, are fundamental subatomic particles that play a crucial role in particle physics. Discovered in 1983 at CERN (the European Organization for Nuclear Research), these particles consist of one electron and one positron (the antiparticle of the electron). They are electrically neutral but carry a net charge of zero. LEP particles are primarily used in experiments to study the electroweak force, a fundamental interaction described by the theory of the Standard Model of particle physics. These particles decay into other particles, such as muons and neutrinos, making them valuable tools for probing the structure of matter and the universe at its most fundamental level. The study of LEP particles has provided insights into the weak nuclear force and helped refine our understanding of the Higgs mechanism, which explains how particles acquire mass.
