Feynman diagrams for neutralino pair production at hadron collidersDate: 2015-05-22
Here are some hand-drawn Feynman diagrams for neutralino dark matter pair production at hadron colliders. Note that these diagrams do not take into account neutralino mixings (as in, you won’t see a wino coupling to a higgsino, etc.) or electroweak symmetry breaking - the neutral higgsinos have not mixed with each other yet. The relevant vertices are also given.
These might come in handy if you are reading Neutralino Dark Matter at 14 and 100 TeV.
