Tīmeklis2024. gada 9. janv. · We consider right-handed neutrino pair production in generic Z′ models. We propose a new, model-independent analysis using final states containing a pair of same-sign muons. A key aspect of this analysis is the reconstruction of the RH neutrino mass, which leads to a significantly improved sensitivity. Within the U 1 B − … Tīmeklisobserved smallness of neutrino masses [2{6].

Introducing RH neutrinos leads to a more symmetric theory (lepton-quark analogy), while generating a Majorana mass is more in vogue with grand unified theories8 in which lepton number is often violated in any case.

Tīmeklis2015. gada 9. nov. · The heaviest physical neutrino has mass m 3 much larger than m 2 since the atmospheric RH neutrino makes the dominant contribution to the seesaw mechanism. The model approximates to the two RH neutrino case (as considered previously) where m 1 = 0. The SM with three such RH neutrinos is depicted in … Tīmeklis2024. gada 26. apr. · R-parity conserving supersymmetric models with right-handed (RH) neutrinos are very appealing since they could naturally explain neutrino physics and also provide a good dark matter (DM) candidate such as the lightest supersymmetric particle (LSP).

This fermion obtains mass from the supergravity effects leading to a RH neutrino at the electroweak scale with a mass similar to the gravitino mass.

Tīmeklis2013. gada 22. nov. · Saturation can be reached by inclusion of the right-handed (RH) neutrino contributions in TeV-scale left-right symmetric models with type-II seesaw. This imposes a lower limit on the lightest neutrino mass. Using the 0νββ bounds, we also derive correlated constraints in the RH sector, complimentary to those from direct … TīmeklisThe existence of the tiny neutrino masses observed by neutrino oscillation experiments is one of the most mys-terious problems in the Standard Model (SM).
