We propose an adjoint SU(5)GUT model with a T7 family symmetry, that successfully describes the prevailing SM fermion mass and mixing pattern. The light active neutrino masses can be generated by type I and type III see saw mechanisms. The model predictions for both quark and lepton sectors are in a very good agreement with the experimental data. The model predicts an effective Majorana neutrino m

I will discuss the origin of CP violation in settings with a discrete (flavor) symmetry. In particular, we show that certain discrete symmetries clash with CP in the sense that, in generic settings with such symmetries, one cannot consistently define a proper CP transformation. For such discrete symmetries, CP violation can be purely group theoretical, leading to physical effects such as particle

SNO+ is the successor of the SNO experiment, where the heavy water has been replaced by 780 tons of liquid scintillator (linear alkyl benzene, LAB). SNO+ is located in the SNOLAB underground facility, near Sudbury Ontario Canada, 2 km below the surface to mitigate backgrounds produced by cosmic rays, and in a clean lab environment (class 2000) to reduce external backgrounds. The SNO+ experiment wi

CP violation phase is required for many beyond the Standard Model (SM) scenarios. Experimental results from BaBar, Belle, and most recently from LHCb are very interesting in this respect. It is important to calculate various CP violation parameters within the SM. In the talk, the final state interaction (FSI) phases with the CKM matrix are calculated using the recent experimental results from LHCb

We apply the method of reduction of couplings in a Finite Unified Theory (FUT). The method consists on searching for renormalization group invariant relations among couplings/parameters of a renormalizable theory holding to all orders in perturbation theory. It has a remarkable predictive power since, at the unification scale, it leads to relations between gauge and Yukawa couplings in the dimensi

The new form for the Jarlskog determinant J=Im(V31 V22 V33) is derived after making Det(V) real, and the maximality of the weak CP violation is proved. A string derivation of family unified model SU(7)xU(1) is suggested, and it is speculated delta(PMNS)=+-delta(CKM)

Models beyond the Standard Model with extra scalars are highly motivated by the recent discovery of scalar Higgs boson. The Two Higgs Doublet Model Type III considers the most general case for the scalar potential and Yukawa interactions. We are interested in flavor changing interactions between neutral Higgs bosons and fermions which arises from Yukawa couplings. In particular we study the decay

In addition to the discovery of the long-awaited Higgs boson, the LHC Run I brought us several surprises in flavor physics. Among them, two have attracted a great deal of attention: a hint for Higgs lepton flavor violating decays at CMS and a collection of anomalies in b to s transitions at LHCb, including an intriguing hint for lepton universality violation. In this talk we will discuss some mode

I will consider a general paradigm of a dark sector interacting with the standard model through a set of heavy neutral mediators, and discuss briefly the various possibilities that emerge. I will then concentrate on the neutrino-portal scenario and present some of its more salient features.

In gauging the Standard Model flavor group, anomaly cancellation requires adding fermions. Remarkably their mass is inversely related to the known fermion masses, as in the well known neutrino see-saw. In this case all flavor violating effects turn out to be controlled roughly by the Standard Model Yukawa, suppressing transitions for the light generations. Due to the inverted hierarchy the scale

Flavor physics measurements performed mai

The S3 model is an extension of the SM in which has been imposed a S3 flavor symmetry. In order to give masses to the particles and keep the flavour symmetry unbroken two additional Higgs doubletes are added. The model has three right handed neutrinos which help implement a seesaw mechanism to give light masses to the left handed ones. On this model we calculate the leptonic as well as the baryon

The strategy of constraining the lepton flavor mixing from remnant CP symmetry is investigated in a rather general way. The neutrino mass matrix generally admits four remnant CP transformations which can be derived from the measured lepton mixing matrix in the charged lepton diagonal basis. Conversely, the lepton mixing matrix can be reconstructed from the postulated remnant CP transformations. Al

We study the dicrete symmetries (P, C, T) on the kinematical level.
We found problems in construction of the neutral particles in the (1,0)+(0,1) and (1/2,1/2) representations of the Lorentz Group. As well known the photon has the quantum numbers 1^-, so it is quite relevant
to the relativity. It appears that the answers are connected with the
helicity basis properties, and commutations /antico

Using the fact that the neutrino mixing matrix $U = U^\dagger_{e}U_{\nu}$, where $U_{e}$ and $U_{\nu}$ result from the diagonalisation of the charged lepton and neutrino mass matrices, we analyse the predictions based on the sum rules which the Dirac phase $\delta$ present in $U$ satisfies when $U_{\nu}$ has a form dictated by, or associated with, discrete symmetries and $U_e$ has a ``minimal'' fo

Degenerate neutrino masses need a special flavor symmetry at work for
the tree-level configuration. Majorana neutrinos require SO(3). We show that the presence of threshold corrections to neutrino masses at the electroweak scale may destroy the degenerate pattern and generate the observed neutrino mixing.
Compared to the case with different Majorana CP-phases for each mass
eigenstate, the exa

The OPERA experiment at the Gran Sasso underground laboratory has been designed to study the nu_mu -> nu_tau oscillation in appearance mode in the CNGS neutrino beam. Four nu_tau candidate events have been confirmed so far, using a sub-sample of data from the 2008-2012 runs. Given the number of analysed events and the low background, nu_mu -> nu_tau oscillations have been established with a signif

A spin-space extension is reviewed, which provides information on the standard model. Its defining feature is a common matrix space that describes symmetries
and representations, and leads to limits on these, for given dimension. The model provides additional information on the standard model, whose interpretation
requires an interactive formulation. Within this program, we compare the model’s l

We present a framework to generate the mass hierarchies and mixing angles of the fermionic sector of the Standard Model with two extra Higgs doublets and one right-handed neutrino. The masses of the first and second generation are generated by small quantum effects, explaining the hierarchy with the third generation. The model also generates a natural hierarchy between the first and second generat

The charged fermion masses of the three generations exhibit the two strong hierarchies m3 >> m2 >> m1. We assume that also neutrino masses satisfy a normal ordering and derive the consequences of the hierarchical spectra on the fermionic mixing patterns. The quark and lepton mixing matrices are built in a general framework with their matrix elements expressed in terms of the corresponding four fer

Anomalies in (semi)leptonic $B$-meson decays present interesting patterns
that might be revealing the shape of the new physics to come. I will
review the decays and observables where these appear, discussing the extent up to which the respective SM predictions are understood. In this sense, the most interesting anomaly is, perhaps, the violation of lepton universality implied by a recent measure

We propose a renormalisable model based on $A_4$ family symmetry with an
$SU(5)$ grand unified theory (GUT) which leads to the minimal supersymmetric standard model (MSSM) with a two right-handed neutrino seesaw mechanism.
Discrete $\mathbb{Z}_9\times \mathbb{Z}_6$ symmetry provides the fermion mass hierarchy
in both the quark and lepton sectors. Proton decay is highly suppressed by these symme

In this talk we shall give an overview of unified models of quark and lepton (including especially neutrino) masses and mixing based on discrete CP and family symmetries. Various different approaches to model building will be described, denoted as direct, semi-direct and indirect. The minimal predictive seesaw model is introduced and embedded into a fairly complete SU(5) SUSY GUT with A4 symmetry.
