WebThe left side of this Feynman diagram represents the main production mode of the Higgs boson at the LHC. The incoming particles are two gluons, one from each colliding proton. The gluons then exchange a virtual top quark, which produces a virtual top-antitop pair. This pair then annihilates to produce a real Higgs boson. Higgs decay: WebNov 15, 2016 · The experiments that physicists really care about involve Feynman diagrams with loops. Loops represent situations in which particles emit and then reabsorb additional particles. When an electron collides with a positron, there’s an infinite number of intermediate collisions that can take place before the final muon and antimuon pair …

At the tree level there is one Feynman diagram for each process, e− e+ µ− µ+ p1 p2 p′ 1 p ′ 2 q e− µ− e− µ− k p k′ p′ q˜ (1) and the two diagrams look like the same diagram from two different points of view. Indeed, both diagrams have identical arrangements of lines and ... http://hyperphysics.phy-astr.gsu.edu/hbase/Solids/coop.html WebA diagram is constructed when the lines are connected together in pairs to form edges of a graph, with no stray lines leaving. The general procedure is to first figure out which diagrams are relevant to the problem being solved, and then use some Feynman rules to calculate a value for each diagram. tincture that has vicodin like effects
