“…The quark sector with three generations contains a CP violating complex phase called the Cabibbo-Kobayashi-Maskawa (CKM) phase. Recently, a nonzero phase has been hinted at in the lepton sector as well [28][29][30]. The existence of CP violation (CPV) in nature and the SUSY CP problem are reconciled by the idea of that CP is a gauge symmetry [31,32], which is broken spontaneously [33].…”

We study the contributions of supersymmetric models with a U(1) horizontal symmetry and only spontaneous CP breaking to various lepton flavor observables, such as μ → eγ and the electron electric dipole moment. We show that both a horizontal symmetry and a lack of explicit CP violation can alleviate the existing bounds from such observables. The undetermined $$ \mathcal{O} $$ O (1) coefficients in such mass matrix models muddle the interpretation of the bounds from various flavor observables. To overcome this, we define a new fine-tuning measure for different observables in such setups. This allows us to study how naturally the observed IR flavor observables can emerge from a given mass matrix model. We use our flavor-naturalness measure in study of our supersymmetric models and quantify the degree of fine tuning required by the bounds from various lepton flavor observables at each mass scale of sleptons, neutralinos, and charginos.

“…There is some tension between measurements of this phase. The NOνA [29] experiment favors δ CP < π, still allowing a CP-conserving phase, while T2K [30] favors δ CP > π and disfavors CP-violation at the level of 2σ.…”

“…Marvelous data from several ongoing experiments such as Super-K [10], IceCube-DeepCore [11], ANTARES [12], Daya Bay [13], RENO [14], Tokai to Kamioka (T2K) [15,16], and NuMI Off-axis ν e Appearance (NOνA) [17] have been improving our knowledge about the neutrino oscillation parameters beyond expectations. Because of this fascinating progress, we have been able to build a robust, simple, three-flavor neutrino oscillation paradigm which successfully accommodate most of the data [3][4][5][6].…”

We explore the role of matter effect in the evolution of neutrino oscillation parameters in the presence of lepton-flavor-conserving and lepton-flavor-violating neutral-current non-standard interactions (NSI) of the neutrino. We derive simple approximate analytical expressions showing the evolution of mass-mixing parameters in matter with energy in the presence of standard interactions (SI) and SI+NSI (considering both positive and negative values of real NSI parameters). We observe that only the NSI parameters in the (2,3) block, namely εμτ and (γ − β) ≡ (εττ− εμμ) affect the modification of θ23. Though all the NSI parameters influence the evolution of θ13, εeμ and εeτ show a stronger impact at the energies relevant for DUNE. The solar mixing angle θ12 quickly approaches to ∼ 90° with increasing energy in both SI and SI+NSI cases. The change in ∆$$ {m}_{21,m}^2 $$ m 21 , m 2 is quite significant as compared to ∆$$ {m}_{31,m}^2 $$ m 31 , m 2 both in SI and SI+NSI frameworks for the energies relevant for DUNE baseline. Flipping the signs of the NSI parameters alters the way in which mass-mixing parameters run with energy. We demonstrate the utility of our approach in addressing several important features related to neutrino oscillation such as: a) unraveling interesting degeneracies between θ23 and NSI parameters, b) estimating the resonance energy in presence of NSI when θ13 in matter becomes maximal, c) figuring out the required baselines and energies to have maximal matter effect in νμ → νe transition in the presence of different NSI parameters, and d) studying the impact of NSI parameters εμτ and (γ − β) on the νμ → νμ survival probability.

“…[24,25]. In 2021, T2K and NOνA updated their results with the best-fit value from T2K remaining the same, δ D = 252 •+40 • −33 • (NO) and 281 •+28 • −31 • (IO) [26] while the NOνA best fit changes to δ D = 148 •+49 • −157 • for NO [27]. The tension still remains with a difference of 104 • in the best fit values.…”
