Researchers at the Institute of Nuclear Physics of the Polish Academy of Sciences suggest that the Higgs boson may connect with “new physics” through decays into exotic particles, as described in Hidden Valley models. These models propose that future particle accelerators might detect these exotic decays, offering insights beyond the Standard Model. The Higgs boson, known for imparting mass to elementary particles, may decay in a way that has yet to be observed at the Large Hadron Collider (LHC).
The Hidden Valley concept posits that ordinary particles lie in a low-energy group, while exotic particles exist in a high-energy domain, separated by an energy barrier. Higgs bosons could act as intermediaries, decaying into exotic particles that subsequently convert into quark-antiquark pairs detectable as jets.
Future lepton colliders, like the Compact Linear Collider (CLIC) and Future Circular Collider (FCC), are anticipated to improve the detection of these exotic decays by providing a less complex background compared to proton collisions at the LHC. The study indicates a promising potential to observe these phenomena, elevating our understanding of particle physics and possibly uncovering new physics avenues. The research builds on theoretical predictions and aims to refine understanding of the Higgs boson’s role in potential new physics frameworks.
