“…The models are only self-consistent if there exist exactly three generations of fermions as a result of the triangle gauge anomalies and QCD asymptotic freedom [229,414,433]. Moreover, they can host a dark matter candidate [230,423,[429][430][431][434][435][436][437][438][439][440][441][442][443][444][445], generate neutrino masses [295-299, 446, 447], among other things [448][449][450][451][452][453][454][455][456].…”

A call for new physics: The muon anomalous magnetic moment and lepton flavor violation

We review how the muon anomalous magnetic moment (g − 2) and the quest for lepton flavor violation are intimately correlated. Indeed the decay µ → eγ is induced by the same amplitude for different choices of in-and outgoing leptons. In this work, we try to address some intriguing questions such as:Which hierarchy in the charged lepton sector one should have in order to reconcile possible signals coming simultaneously from g − 2 and lepton flavor violation?What can we learn if the g − 2 anomaly is confirmed by the upcoming flagship experiments at FERMILAB and J-PARC, and no signal is seen in the decay µ → eγ in the foreseeable future? On the other hand, if the µ → eγ decay is seen in the upcoming years, do we need to necessarily observe a signal also in g − 2?.In this attempt, we generally study the correlation between these observables in a detailed analysis of simplified models. We derive master integrals and

“…The candidate includes a scalar combination of χ 0 4 and Ξ 0 3 , or a vector W 0 34 . The key-difference between the 3-4-1-1 model and the previous 3-3-1-1 [20][21][22][23][24][25][26] and 3-3-1 [40][41][42][43][44][45][46][47][48][49][50][51] models is that the present proposal can contain multicomponent dark matter. This is because the matter parity actually contains two single matter parities, characterized by (n, m) parameters, which do not exit in the previous studies.…”

It is well established that the SU(P) L gauge symmetry for P ≥ 3 can address the question of fermion generation number due to the anomaly cancellation, but it neither commutes nor closes algebraically with electric and baryon-minus-lepton charges. Hence, two U(1) factors that determine such charges are required, yielding a complete gauge symmetry, SU(P) L ⊗ U(1) X ⊗ U(1) N , apart from the color group. The resulting theory manifestly provides neutrino mass, dark matter, inflation, and baryon asymmetry of the universe. Furthermore, this gauge structure may present kinetic mixing effects associated to the U(1) gauge fields, which affect the electroweak precision test such as the ρ parameter and Z couplings as well as the new physics processes. We will construct the model, examine the interplay between the kinetic mixing and those due to the symmetry breaking, and obtain the physical results in detail.

Lepton masses and mixings in a T′ flavored 3-3-1 model with type I and type II seesaw mechanisms

We propose a renormalizable T ′ flavor model based on the SU (3) C × SU (3) L × U (1) X × U (1) L gauge symmetry, consistent with the observed pattern of lepton masses and mixings.The small masses of the light active neutrinos are produced from an interplay of type I and type II seesaw mechanisms, which are induced by three heavy right-handed Majorana neutrinos and three SU (3) L scalar antisextets, respectively. Our model is only viable for the scenario of normal neutrino mass hierarchy, where the obtained physical observables of the lepton sector are highly consistent with the current neutrino oscillation experimental data. In addition, our model also predicts an effective Majorana neutrino mass parameter of m β ∼ 1.41541 × 10 −2 eV, a Jarlskog invariant of the order of J CP ∼ −0.032 and a leptonic Dirac CP violating phase of δ = 238 • , which is inside the 1σ experimentally allowed range.
