Data-driven analysis of a SUSY GUT of flavour

We present a data-driven analysis of a concrete Supersymmetric (SUSY) Grand Unified Theory (GUT) of flavour, based on SU (5) × S 4 , which predicts charged fermion and neutrino mass and mixing, and where the mass matrices of both the Standard Model and the Supersymmetric particles are controlled by a common symmetry at the GUT scale. This framework also predicts non-vanishing non-minimal flavour violating effects, motivating a sophisticated data-driven parameter analysis to uncover the signatures and viability of the model. The computer-intensive Markov-Chain-Monte-Carlo (MCMC) based analysis, the first of its kind to include a large range of flavour as well as dark matter and SUSY observables, predicts distributions for a range of physical quantities which may be used to test the model. The predictions include maximally mixed sfermions, µ → eγ close to its experimental limit and successful bino-like dark matter with nearby winos (making direct detection unlikely), implying good prospects for discovering winos and gluinos at forthcoming collider runs. The results also demonstrate that the Georgi-Jarlskog mechanism does not provide a good description of the splitting of down type quark masses and charged leptons, while neutrinoless double beta decay is predicted at observable rates.

“…The purple (green) shaded area arises upon variation of the lepton mixing parameters and mass squared differences within the experimentally preferred 3 σ ranges for NO (IO) [76]. Values of m 0 disfavoured by the cosmological bound on the sum of the light neutrino masses [81] are identified by a vertical grey band, while regimes of m ee already disfavoured by searches for 0νββ decay [82] are indicated by a horizontal grey band GERDA [84]; m ee < (200 ÷ 433) meV also for 76 Ge by the Majorana Demonstrator [85]; m ee < (75 ÷ 350) meV for 130 Te, obtained by CUORE [86]. With further improvement of the experimental limits, certain combinations of group theory parameters in the different cases could be disfavoured, at least, if the light neutrino mass spectrum is assumed to follow IO.…”

Flavour and CP symmetries in the inverse seesaw

et al. 2022

We consider an inverse seesaw mechanism of neutrino mass generation in which the Standard Model is extended by $$3+3$$ 3 + 3 (heavy) sterile states, and endowed with a flavour symmetry $$G_f$$ G f , $$G_f=\Delta (3 \, n^2)$$ G f = Δ ( 3 n 2 ) or $$G_f=\Delta (6 \, n^2)$$ G f = Δ ( 6 n 2 ) , and a CP symmetry. These symmetries are broken in a peculiar way, so that in the charged lepton sector a residual symmetry $$G_\ell $$ G ℓ is preserved, while the neutral fermion sector remains invariant under the residual symmetry $$G_\nu =Z_2 \times CP$$ G ν = Z 2 × C P . We study the concrete setup, where the Majorana mass term for three of the sterile states conserves $$G_\nu $$ G ν , while the remaining mass terms (i.e. couplings of left-handed leptons and heavy sterile states, as well as the Dirac-type couplings among the latter) do not break the flavour or CP symmetry. We perform a comprehensive analysis of lepton mixing for different classes of residual symmetries, giving examples for each of these, and study in detail the impact of the additional sterile states on the predictions for lepton mixing. We further confront our results with those obtained in the model-independent scenario, in which the light neutrino mass matrix leaves the residual symmetry $$G_\nu $$ G ν intact. We consider the phenomenological impact of the inverse seesaw mechanism endowed with flavour and CP symmetries, in particular concerning effects of non-unitarity of the lepton mixing matrix (which strongly constrain the parameter space of the scenario), prospects for neutrinoless double beta decay and for charged lepton flavour violating processes.

“…The study of neutrinoless double β-decay (A, Z) → (A, Z + 2) + e − + e − is the most sensitive way which could allow us to reveal the Majorana nature of neutrinos with definite masses ν i . In recent experiments the following lower limits on half-lives of the 0νββ-decay of different nuclei were reached: T 1/2 ( 76 Ge) > 9•10 25 yr (GERDA) [28], T 1/2 ( 136 Xe 136 ) > 10.7•10 25 yr (KamLAND-Zen) [29], T 1/2 ( 130 Te) > 3.2 • 10 25 yr (CUORE) [30].…”

In the introductory part we briefly consider basics of neutrino oscillations and convenient phenomenology of neutrino oscillations in vacuum. Main part of this report is dedicated to a discussion of a plausible BSM scenarios of neutrino mass generation, based on assumptions of massless left-handed SM neutrinos and violation of the total lepton number. It is stressed that search for light sterile neutrinos and neutrinoless double β-decay could provide a crucial tests of this scenarios.
