B+ decay feynman diagram
Webthe three and in fact weighs more than B and C combined, so it can decay to B+C. The lowest order Feynman diagram describing this decay (A → B +C): As can be seen there are no internal lines, and the diagram includes only a single vertex. Using the Feynman rules as listed in the previous paragraph: (a) We label the incoming and outgoing four ... WebThe nal values are L = +1 and Le= (+1)+( 1) = 0 again. The Feynman diagram is below. This is structurally very similar to the ones we have seen before. However, the nal state is much more complicated because we have a three-body nal state.

WebThe 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 WebThe leading-order Feynman diagrams for electron capture decay. An electron interacts with an up quark in the nucleus via a W boson to create a down quark and electron neutrino. Two diagrams comprise the leading (second) order, though as a virtual particle, the type (and charge) of the W-boson is indistinguishable.
