“…There are several supersymmetric models [180,[187][188][189][190][191] which generate neutrino mass via different down-type quarks or charged leptons in the loop and consequently induce the operators O 3 and O 2 , respectively. Finally, there are models with only heavy particles in the loop such as the inert Zee model [192] or supersymmetric models with R-parity conservation [193,194].…”

From the Trees to the Forest: A Review of Radiative Neutrino Mass Models

A plausible explanation for the lightness of neutrino masses is that neutrinos are massless at tree level, with their mass (typically Majorana) being generated radiatively at one or more loops. The new couplings, together with the suppression coming from the loop factors, imply that the new degrees of freedom cannot be too heavy (they are typically at the TeV scale). Therefore, in these models there are no large mass hierarchies and they can be tested using different searches, making their detailed phenomenological study very appealing. In particular, the new particles can be searched for at colliders and generically induce signals in lepton-flavor and lepton-number violating processes (in the case of Majorana neutrinos), which are not independent from reproducing correctly the neutrino masses and mixings. The main focus of the review is on Majorana neutrinos. We order the allowed theory space from three different perspectives: (i) using an effective operator approach to lepton number violation, (ii) by the number of loops at which the Weinberg operator is generated, (iii) within a given loop order, by the possible irreducible topologies. We also discuss in more detail some popular radiative models which involve qualitatively different features, revisiting their most important phenomenological implications. Finally, we list some promising avenues to pursue.

“…[19], with a singlet Majorana fermion ψ S of hypercharge parameter α = 0, that determines also the hypercharges of the vector-like fermion doublet ψ D , the singlet scalar φ S , and the complex doublet scalar φ D . The alternative case α = −2, called the Inert Zee Model, has previously been analysed and found to be consistent with constraints from neutrino oscillation, dark matter and lepton-flavour violation data [29]. A doublet-triplet model, T1-2-F with α = −1, has also been analysed in a similar way [30].…”

We present a detailed study of a combined singlet-doublet scalar and singletdoublet fermion model for dark matter. These models have only been studied separately in the past. We show that their combination allows for the radiative generation of neutrino masses, but that it also implies the existence of lepton-flavour violating (LFV) processes. We first analyse the dark matter, neutrino mass and LFV aspects separately. We then perform two random scans for scalar dark matter imposing Higgs mass, relic density and neutrino mass constraints, one over the full parameter space, the other over regions where scalar-fermion coannihilations become important. In the first case, a large part of the new parameter space is excluded by LFV, and the remaining models will be probed by XENONnT. In the second case, direct detection cross sections are generally too small, but a substantial part of the viable models will be tested by future LFV experiments. Possible constraints from the LHC are also discussed.

“…Mô hình Zee được đề xuất như một hướng mở rộng của mô hình chuẩn cho việc sinh khối lượng neutrino ở các bổ đính bậc cao [2]. Các mô hình mở rộng mô hình chuẩn cũng đem lại nhiều hiệu quả Vật lý mới cần nghiên cứu, các Vật lý mới này được đưa ra từ các kênh rã vi phạm số lepton thế hệ [5,9], từ các kênh rã của các boson trung hòa ra các photon … [6,8]. Đây là các kênh rã hiếm và hiện nay đang rất được quan tâm nghiên cứu, đóng góp của các boson chuẩn trong các kênh rã này là phần quan trọng không thể thiếu, nhất là ở bậc một vòng.…”

By adding scalars, the Zee model, as standard model byond, has generated masses for the neutrinos. Due to the addition of new scalars, the mass spectrum and physical states of the particles are different from ones of the standard model. Using general Lagrangian, the interactions of gauge bosons with fermions and Higgs bosons are given. These vertices are the basis for the study of decay processes such as: lepton flavor violating Higgs decays, Higgs decays to two photon.
