The postdoc position is limited to a duration of three years with the possibility of … WebHiggs production: The left side of this Feynman diagram represents the main production mode of the Higgs boson at the LHC. The incoming particles are two gluons, one from each colliding proton. The gluons then exchange a virtual top quark, which produces a virtual top-antitop pair. This pair then annihilates to produce a real Higgs boson. Higgs ...

Web14 de jan. de 2024 · To experimentally constrain this shape we must measure the Higgs boson self-coupling, which is accessible at the LHC through the simultaneous production of two Higgs bosons. The selected student will join the Portuguese ATLAS team, working in close collaboration with theorists and integrated into our international collaboration. WebThe cause of the screening of the weak interactions at long distances puzzled the high-energy community for more nearly half a century. With the discovery of the Higgs boson a new era started with direct experimental information on the physics behind the breaking of the electroweak symmetry. This breaking plays a fundamental role in our understanding …
