Modular flavor symmetry and vector-valued modular forms
Journal of High Energy Physics, 2022 We revisit the modular flavor symmetry from a more general perspective. The scalar modular forms of principal congruence subgroups are extended to the vector-valued modular forms, then we have more possible finite modular groups including Γ N and Γ N ′ $$

Minimally modified Fritzsch texture for quark masses and CKM mixing
Journal of High Energy Physics, 2023 The Standard Model does not constrain the form of the Yukawa matrices and thus the origin of fermion mass hierarchies and mixing pattern remains puzzling.

Lepton-flavour violating decays in theories with dimension 6 operators [PDF]
, 2015 Despite a large experimental effort, so far no evidence for flavour-violating decays of charged leptons such as l i → l j γ and l i → l j l k l k has been found.

Common origin of θ 13 and dark matter within the flavor symmetric scoto-seesaw framework
Journal of High Energy Physics, 2022 To understand the observed pattern of neutrino masses and mixing as well as to account for the dark matter we propose a hybrid scoto-seesaw model based on the A 4 discrete flavor symmetry.

Low energy effective theories of composite dark matter with real representations [PDF]
SciPost Physics CoreWe consider pseudo Nambu-Goldstone bosons arising from Dirac fermions transforming in real representations of a confining gauge group as dark matter candidates.

Neutrino physics in TeV scale gravity theories [PDF]
Physical Review D, 2022 In this paper, the general features of the neutrino sector in TeV scale quantum gravity theories, such as ADD and Many Species Theory, is investigated. This class of theories has an inherent way to generate small neutrino masses.

Proceedings of European Physical Society Europhysics Conference on High Energy Physics — PoS(EPS-HEP 2009), 2010 After an overture and a non-technical exposition of the relevant theoretical framework including a brief discussion of some of the most popular extensions of the Standard Model, we will compile a list of 20 goals in flavour physics that could be reached already in the next decade. In addition to K, D and B_{s,d} decays and lepton flavour violation also

Predicting the values of the leptonic CP violation phases in theories with discrete flavour symmetries [PDF]
, 2014 Using the fact that the neutrino mixing matrix U=Ue†Uν, where Ue and Uν result from the diagonalisation of the charged lepton and neutrino mass matrices, we consider a number of forms of Uν associated with a variety of discrete symmetries: i) bimaximal ...

Wrinkles in the Froggatt-Nielsen mechanism and flavorful new physics
Journal of High Energy Physics, 2023 When the Froggatt-Nielsen mechanism is used to explain the Standard Model flavor hierarchy, new physics couplings are also determined by the horizontal symmetry.
