WebIn this paper we study various particle physics effects of a light, scalar dark energy field with chameleon-like couplings to matter. We show that a chameleon model with only matter couplings will induce a coupling to photons. In doing so, we derive the first microphysical realization of a chameleonic dark energy model coupled to the electromagnetic field … Web24 de nov. de 2024 · November 24, 2024 • Physics 13, 174. A theoretical approach called naturalness has helped physicists understand several particle physics puzzles—but the Higgs boson’s unsuitably small mass is currently foiling this strategy.

The scale of this instability, determined as the Higgs field value at which the potential drops below the electroweak minimum, is about 1011 GeV. However, such a scale is unphysical as it is …

WebPhysicists look for traces of these particles in data collected by the detectors. The challenge is that these particles are also produced in many other processes, plus the Higgs boson only appears in about one in a billion LHC collisions.
