Exempel på hur man kan använda LEPTON i en mening

• A celebrated example is the case of deep inelastic scattering, in which a virtual space-like photon is exchanged between the incoming lepton and the incoming hadron.
• Like the electron, the muon, and the three neutrinos, the tau is a lepton, and like all elementary particles with half-integer spin, the tau has a corresponding antiparticle of opposite charge but equal mass and spin.
• In the Minimal Supersymmetric Standard Model, baryon number and lepton number are no longer conserved by all of the renormalizable couplings in the theory.
• In particle physics, majorons (named after Ettore Majorana) are a hypothetical type of Goldstone boson that are conjectured to mediate the neutrino mass violation of lepton number or B − L in certain high energy collisions such as.
• The first two sets consisted of twelve values; 1 lepton, 2, 5, 10, 20, 40, 60, 70, 80 and 90 lepta, 1 drachma and 2 drachmae.
• There are two main types of particle colliders, which differ in the types of particles they collide: lepton colliders and hadron colliders.
• This process, inverse beta decay, conserves lepton number, as the incoming antineutrino has lepton number −1, while the outgoing positron (antielectron) also has lepton number −1.
• His formulation, carried out in collaboration with Nobel Laureate Abdus Salam, of the original gauge theory of quark–lepton unification, and their resulting insight that violations of baryon and lepton numbers, especially those that would manifest in proton decay, are likely consequences of such a unification, provide cornerstones of modern particle physics today.
• The set of eight stamps, with denominations of 1 lepton, 5, 10, 25 and 50 lepta, 1 drachma and 2 and 5 drachmae, depicted an infantryman aiming a rifle while others look on; the 10 lepta and 25 lepta values were inscribed only with ΗΠΕΙΡΟΣ (these were released in February), while the others read ΑΥΤΟΝΟΜΟΣ ΗΠΕΙΡΟΣ (these were released in March with the exception of the 5 drachma, which came out in April).
• Interest in preon models peaked in the 1980s but has slowed, as the Standard Model of particle physics continues to describe physics mostly successfully, and no direct experimental evidence for lepton and quark compositeness has been found.
• Since weak hypercharge is always conserved within the Standard Model and most extensions, this implies that baryon number minus lepton number is also always conserved.
• In the currently accepted Standard Model, lepton number is nearly conserved at temperatures below the TeV scale, but tunneling processes can change this number; at higher temperature it may change through interactions with sphalerons, particle-like entities.
• A separate quantum number for each generation is more useful: electronic lepton number (+1 for electrons and electron neutrinos), muonic lepton number (+1 for muons and muon neutrinos), and tauonic lepton number (+1 for tau leptons and tau neutrinos).
• These particle–antiparticle pairs carry various kinds of charges, such as color charge if they are subject to quantum chromodynamics such as quarks or gluons, or the more familiar electromagnetic charge if they are electrically charged leptons or quarks, the most familiar charged lepton being the electron and since it is the lightest in mass, the most numerous due to the energy–time uncertainty principle as mentioned above; e.
• In particle physics the semileptonic decay of a hadron is a decay caused by the weak force in which one lepton (and the corresponding neutrino) is produced in addition to one or more hadrons.
• However, if the lepton number is not conserved, or equivalently the neutrino is its own antiparticle, another kind of process can occur: the so-called neutrinoless double electron capture.
• The two types of weak interactions they (rarely) engage in are neutral current (which involves the exchange of a Z boson and only results in deflection) and charged current (which involves the exchange of a W boson and causes the neutrino to convert into a charged lepton: an electron, a muon, or a tauon, or one of their antiparticles, if an antineutrino).
• One possible WDM candidate particle with a mass of a few keV comes from introducing two new, zero charge, zero lepton number fermions to the Standard Model of Particle Physics: "keV-mass inert fermions" (keVins) and "GeV-mass inert fermions" (GeVins).
• The high-energy analog of the neutrinoless double beta decay process is the production of same-sign charged lepton pairs in hadron colliders; it is being searched for by both the ATLAS and CMS experiments at the Large Hadron Collider.
• In particle physics, the Pontecorvo–Maki–Nakagawa–Sakata matrix (PMNS matrix), Maki–Nakagawa–Sakata matrix (MNS matrix), lepton mixing matrix, or neutrino mixing matrix is a unitary.
