Extended Data Fig. 2: Higgs boson candidate events.
From: A portrait of the Higgs boson by the CMS experiment ten years after the discovery
(upper) An event display of a candidate H → ZZ → eeμμ. (lower) An event display of an H → bb candidate produced in association with a boson decaying into an electron–positron pair, in pp collisions at \(\sqrt{s}=13\,{\rm{TeV}}\) recorded by CMS. The charged-particle tracks, as reconstructed in the inner tracker, are shown in yellow; the electrons are shown in green, the energy deposited by the electrons in the ECAL is shown as large green towers, the size of which is proportional of the amount of energy deposited; the blue towers are indicative of the energy deposits in the HCAL, while the red boxes are the muon chambers crossed by the muons (red tracks); the yellow cones represent the reconstructed jets. (lower, inset) The zoom into the collision region shows the displaced secondary vertices (in red) of the two b quarks decaying away from the primary vertex (in yellow). One of the bottom hadrons decays into a charm hadron that moves away from the secondary vertex before decaying (b → c → X; vertex in cyan).
