The top quark being an unstable particle, it decays mostly via a W boson and b quark. The W bosons are also transients and they decay, in turn, either leptonically (electron\/muon\/tau and a corresponding neutrino) or, hadronically, to a pair of quarks which produce jets or sprays of particles in the detector (<a rel=\"noreferrer noopener\" href=\"https:\/\/cms.cern\/news\/detecting-creation-top-quarks-out-light\" target=\"_blank\">link<\/a>).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists of the CMS and TOTEM collaborations have looked for evidence of this process in the data collected at the LHC in 2017.
