Doing this would be no simple task, in fact, it would require the largest experiment and most sophisticated machine in human history. In this way, the search for the Higgs boson itself has pushed both particle accelerator and detector technology to its limits — with the ultimate ...
or in our jargon, five sigma. That was the requirement for discovering the Higgs boson. This super-precise measurement of the W boson doesn’t have five sigma…it hasseven sigma. That means, if we trust the analysis team, then a measurement like this could come accidentally out of the St...
The Standard Model is seriously lacking, in other words, and one of the reasons there is so much excitement about Higgs boson is because it would help fill in the gaps of the Standard Model explanation.There's little doubt that the Standard Model is only a temporary quick fix in the ...
1 First publications about the discovery of the Higgs boson: CMS Collaboration,“Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC”. ATLAS Collaboration, “Observation of a New Particle in the Search for the Standard Model Higgs Boson with the ATLAS ...
So far, all the mea- surements of the discovered new particle [3–10] are well com- patible with the scalar boson predicted by the Standard Model (SM) [11–15]. It is well known that the SM cannot be the final theory of nature. Theoretically, successful explanation of some prob- ...
Indeed, the corresponding Majorana mass term leads, through a type-I seesaw mechanism, to a simple explanation of the neutrino mass problem. 2HDMs with a U(1)X gauge symmetry are also characterized by a richer phenomenology due to the presence of a massive Z′ gauge boson that arises after...
We propose an extension of the scalaron-Higgs model by a non-minimal coupling of the Standard Model Higgs boson to the quadratic Ricci scalar resulting in a Higgs-dependent scalaron mass. The model predicts a successful stage of effective single-field Starobinsky inflation. It features a multi...
While R-parity is conserved in this model lepton number is explicitly vio- lated. We quantify the impact of the extended neutrino sec- tor on the NMSSM Higgs sector by computing the complete one-loop corrections with full momentum dependence to the Higgs boson masses in a mixed on-shell-DR...
This scenario is mostly constrained by searches for the Z' gauge boson which limits the invisible decay width to less than {\mathcal {O}}(30) eV. As those constraints do not apply in the real scalar model, it is possible to obtain an invisible decay width in the MeV range. Finally, ...
