WebMar 17, 2024 · The right-handed neutrinos are fascinating conjectures with, potentially, critical roles in the evolution of the Universe. First of all, the right-handed neutrinos are singlets under the electromagnetic, the weak, and the strong interactions; for this reason they are also called ‘sterile neutrinos’. Sterile neutrinos (or inert neutrinos) are hypothetical particles (neutral leptons – neutrinos) that are believed to interact only via gravity and not via any of the other fundamental interactions of the Standard Model. The term sterile neutrino is used to distinguish them from the known, ordinary active neutrinos in the Standard Model, which carry an isospin charge of ±+1/ 2 and engage in the weak interaction. The term typically refers to neutrinos with right-handed chirality (see right-hande…

WebOct 11, 2016 · The independent set of SME coefficients in the Hamiltonian (5) can trigger the oscillation between left-handed neutrinos and right-handed antineutrinos. These oscillations always exhibit direction dependence and are absent in the first two terms of the series . In other words, the SME coefficients that produce neutrino-antineutrino mixing ... WebMay 3, 2024 · The right-handed neutrinos later decay and generate a lepton asymmetry, which is partially converted to a baryon asymmetry by Standard Model sphaleron processes. We find that a sufficient asymmetry can be generated for a wide range of right-handed neutrino masses and reheating temperatures. banks market cap
