In particle physics, a lepton is an elementary particle of half-integer spin (spin ⁠ 1 / 2 ⁠) that does not undergo strong interactions. [1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), including the electron, muon, and tauon, and neutral leptons, better known as neutrinos.

Jan 20, 2023 · Leptons are elementary particles, which means that they are not made from any smaller particles. There are six known types of lepton (12 if you count their anti-particles). Three of these are...

Jul 18, 2023 · A lepton is an elementary half-integer spin particle that does not get involved in strong interactions. Learn its types, history, properties and lepton numbers.

Nov 6, 2024 · Step 1: Determine the lepton number of all the particles on both sides of the equation. Step 2: Identify the lepton number of X. If the lepton number must be conserved, X must also have a lepton number of –1. Step 3: State the particle X.

Leptons and quarks are the basic building blocks of matter, i.e., they are seen as the "elementary particles". There are six leptons in the present structure, the electron, muon, and tau particles and their associated neutrinos.

A lepton is an elementary, half-integer spin (spin 1⁄2) particle that does not undergo strong interactions. Particles that do participate in strong interactions are called hadrons . There are six leptons in the present structure, the electron, muon, …

lepton, any member of a class of subatomic particles that respond only to the electromagnetic force, weak force, and gravitational force and are not affected by the strong force. Leptons are said to be elementary particles; that is, they do not appear to …

There are three well-known leptons that are electrically charged: Electron (e), Tauon (τ), and Muon (μ). While the three leptons that are electrically neutral are the neutrinos (v). There is also an associated antiparticle for each lepton, having the same mass but charged oppositely.

Jul 31, 2017 · There are three types of leptons: the electron (e -), the muon (μ -), and the tauon (τ -), one for each generation. These leptons have antiparticles, each with a charge of +1.6 x 10 −19 C: the positron (e +), the antimuon (μ +), and the antitauon (τ +), respectively. Neutrinos are chargeless, and almost massless.

May 9, 2018 · lepton (lĕp´tŏn´) [Gr.,=light (i.e., lightweight)], class of elementary particles [1] that includes the electron [2] and its antiparticle [3], the muon [4] and its antiparticle, the tau and its antiparticle, and the neutrino [5] and antineutrino associated with each of these particles.
