Open AccessFlavor symmetries in an SU(5) model of grand unification
We investigate the options for imposing flavor symmetries on a minimal renormalizable non-supersymmetric SU(5) grand unified theory, without introducing additional flavor-related fields. Such symmetries reduce...

Open AccessFlavor symmetries in the Yukawa sector of non-supersymmetric SO(10): numerical fits using renormalization group running
We consider a class of SO(10) models with flavor symmetries in the Yukawa sector and investigate their viability by performing numerical fits to the fermion masses and mixing parameters. The fitting procedure ...

Open AccessThreshold effects in SO(10) models with one intermediate breaking scale
Despite the successes of the Standard Model of particle physics, it is known to suffer from a number of deficiencies. Several of these can be addressed within non-supersymmetric theories of grand unification b...

Open AccessTesting lepton flavor models at ESSnuSB
We review and investigate lepton flavor models, stemming from discrete non- Abelian flavor symmetries, described by one or two free model parameters. First, we confront eleven one- and seven two-parameter mode...

Open AccessDecaying dark matter in halos of primordial black holes
We investigate photon signatures of general decaying dark-matter particles in halos of primordial black holes. We derive the halo-profile density and the total decay rate for these combined dark-matter scenari...

Open AccessFits to non-supersymmetric SO(10) models with type I and II seesaw mechanisms using renormalization group evolution
We consider numerical fits to non-supersymmetric SO(10)-based models in which neutrino mass is generated by the type-I or type-II seesaw mechanism or a combination of both. The fits are performed with a sophis...

Open AccessFull parameter scan of the Zee model: exploring Higgs lepton flavor violation
We study the general Zee model, which includes an extra Higgs scalar doublet and a new singly-charged scalar singlet. Neutrino masses are generated at one-loop level, and in order to describe leptonic mixing, ...

Open AccessRenormalization group running of fermion observables in an extended non-supersymmetric SO(10) model
We investigate the renormalization group evolution of fermion masses, mixings and quartic scalar Higgs self-couplings in an extended non-supersymmetric SO(10) model, where the Higgs sector contains the 10 ...
