Anomaly-free ALP from non-Abelian flavor symmetry
Chengcheng Han, M. L. López-Ibáñez, Aurora Melis +2
Motivated by the Xenon1T excess in electron-recoil measurements, we investigate the prospects of probing axion-like particles (ALP) in lepton flavor violation experiments. In parti…
Constraining Low-Scale Flavor Models with and Lepton Flavor Violation
M. L. López-Ibáñez, Aurora Melis, M. Jay Pérez +2
We present here two concrete examples of models where a sub-TeV scale breaking of their respective and flavor symmetries is able to account for the recentl…
Implications of the Muon g-2 result on the flavour structure of the lepton mass matrix
Lorenzo Calibbi, M. L. López-Ibáñez, Aurora Melis +1
The confirmation of the discrepancy with the Standard Model predictions in the anomalous magnetic moment by the Muon g-2 experiment at Fermilab points to a low scale of new physics…
Controlled fermion mixing and FCNCs in a 3+1 Higgs Doublet Model
A. E. Cárcamo Hernández, Ivo de Medeiros Varzielas, M. L. López-Ibáñez +1
We propose a 3+1 Higgs Doublet Model based on the family symmetry supplemented by several auxiliary cyclic symmetries leading to viable Yukawa textures for the Standard Mod…
Lepton flavour violation from an anomaly-free leptophilic axion-like particle
C. Han, M. L. López-Ibáñez, A. Melis +2
Motivated by the recent Xenon1T result, we study a leptophilic flavour-dependent anomaly-free axion-like particle (ALP) and its effects on charged-lepton flavour violation (CLFV).…
Muon and electron and lepton masses in flavor models
Lorenzo Calibbi, M. L. López-Ibáñez, Aurora Melis +1
The stringent experimental bound on is compatible with a simultaneous and sizable new physics contribution to the electron and muon anomalous magnetic moments $(…
Leptogenesis in with a Universal Texture Zero
Fredrik Björkeroth, Ivo de Medeiros Varzielas, M. L. López-Ibáñez +2
We investigate the possibility of viable leptogenesis in an appealing model with a universal texture zero in the (1,1) entry. The model accommodates the mass spectrum, mixi…
Neutrino masses and lepton mixing from
Andrea Di Iura, M. L. López-Ibáñez, Davide Meloni
We analyse in detail the phenomenological implications for lepton masses and mixing derived by the breaking of the discrete symmetries into the subgroups $Z_2 \time…
Effective Theories of Flavor and the Non-Universal MSSM
Dipankar Das, M. L. López-Ibáñez, M. Jay Pérez +1
Flavor symmetries à la Froggatt-Nielsen~(FN) provide a compelling way to explain the hierarchies of fermionic masses and mixing angles in the Yukawa sector. In Supersymmetric~(SUSY…
Flavour-changing Higgs decays into bottom and strange quarks in supersymmetry
G. Barenboim, C. Bosch, J. S. Lee +2
In this work, we explore the flavour changing decays in a general supersymmetric scenario. In these models, the flavour changing decays arise at loop-level but, origi…
Improved -weapons for Higgs hunting
G. Barenboim, C. Bosch, M. L. López-Ibáñez +1
In this work, we use the results from Higgs searches in the and decay channels at LHC and indirect bounds as BR to constrain the parameter space of a gener…
