A principal goal of the LHC and its high-luminosity upgrade is measuring the Higgs boson interaction with itself. Observing the production of pairs of Higgs bosons is the best way of experimentally establishing this and other Higgs boson…

A particle compatible with the Higgs boson of the standard model (SM) was observed in 2012 by the ATLAS and CMS Collaborations, with a mass of about 125 GeV. Could there be other heavier Higgs bosons, as predicted in some theories trying to…

Top quarks are the heaviest known elementary particles, as heavy as a tungsten atom. In high energy proton proton collisions at the LHC about 10 pairs of a top quark and its antiparticle are produced every second. But they are not here to…
