Space isn’t remote at all. It’s only an hour’s drive away, if your car could go straight upwards.
Feynman diagrams depicting the different (decay-)channels for single-top-production mechanisms. The letters refer to top quarks (t), bottom quarks (b), light quarks (q: u, d, s), W bosons (W), and gluons (g). In each case, the incoming particles are shown on the left and the outgoing particles on the right of the diagram. The circles indicate the W-t-b vertex (interaction), whose coupling strength is governed by the CKM matrix element Vtb.
