List of Feynman diagrams - Wikipedia Diagram Beta decay: beta particle is emitted from an atomic nucleus Compton scattering: scattering of a photon by a charged particle Neutrino-less double beta decay: If neutrinos are Majorana fermions (that is, their own antiparticle), Neutrino-less double beta decay is possible. Several experiments are searching for this. Pair creation and ... Examples of the use of Feynman vertices to describe ... - CERN The corresponding Feynman diagram will be: This is a weak decay of the strange quark. It is an allowed diagonal change between quark generations. The Feynman diagram for the s to u transition is a combination of two quark-W vertices. The pion is derived from a same generation quark weak vertex. Return to top of page Neutron Beta-Decay A rst approximation to neutron beta decay follows by assuming that both the neu-tron and the proton are pointlike Dirac particles which couple directly to a W . The four fermion Feynman diagram using this scheme is shown in gure 3. The matrix element for this decay is easily determined by simply replacing u( ) and u( ) in

conservation laws - Feynman Diagram with antineutrinos and ... The explanation is the same as the one above. Positron has a lepton number equal to − 1 (because its an antilepton) and neutrino has + 1, so that the total lepton number on the RHS is equal to the total lepton number on the LHS. The second Feynman diagram is wrong. W + should decay into a positron-neutrino pair: W + → e + ν e. TikZ-Feynman : how to do a feynman diagram of a beta decay ...

The neutron ejects a W - boson, which then immediately decays to an electron and antineutrino. The neutron becomes a proton. Feynman Diagram - Beta Decay. If the neutron consists of both a W + boson and a W - boson, it is validated in the decay process. Upon decay, it loses the W - boson.

List of Feynman diagrams - Wikipedia

Beta decay - Wikipedia In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is ...
