A bstractFlavor symmetries successfully explain lepton and quark masses and mixings yet it is usually hard to distinguish different models that predict the same mixing angles. Further experimental input could be available, if the agents of flavor breaking are sufficiently low in mass and detectable or if new physics with non-trivial flavor charges is sufficiently low in mass and detectable. The recent hint for lepton-nonuniversality in the ratio of branching fractions B → Kμμ over B → Kee, RK…

Lepton universality violation with lepton flavor conservation in B-meson decays
A bstractAnomalies in semileptonic B-meson decays present interesting patterns that might be revealing the shape of the new physics to come. Under the assumption that neutrino and charged lepton mass
Minimal lepton flavor violation implications of the b → s anomalies
A bstractThe latest measurements of rare b → s decays in the LHCb experiment have led to results in tension with the predictions of the standard model (SM), including a tentative indication of the
Lepton flavor non-universality in B-meson decays from a U(2) flavor model
A bstractWe address the recent anomalies in semi-leptonic B-meson decays using a model of fermion masses based on the U(2) flavor symmetry. The new contributions to b → sℓℓ transitions arise due to a
On the breaking of lepton flavor universality in B decays
A bstractIn view of recent experimental indications of violations of Lepton Flavor Universality (LFU) in B decays, we analyze constraints and implications of LFU interactions, both using an effective

We conduct a systematic study of the impact of new physics in quark-level b→cc s transitions on B physics, in particular rare B decays and B-meson lifetime observables. We find viable scenarios where

Composite leptoquarks and anomalies in B-meson decays
A bstractWe attempt to explain recent anomalies in semileptonic B decays at LHCb via a composite Higgs model, in which both the Higgs and an SU(2)L-triplet leptoquark arise as pseudo-Goldstone bosons
Diagnosing lepton-nonuniversality in b → sℓℓ

Heavy and light scalar leptoquarks in proton decay
We list scalar leptoquarks that mediate proton decay via renormalizable couplings to the Standard Model fermions. We employ a general basis of baryon number violating operators to parameterize

Model building for flavor changing Higgs couplings
If $t\rightarrow hq$ ($q=c,u$) or $h\rightarrow\tau\ell$ ($\ell=\mu,e$) decays are observed, it will be a clear signal of new physics. We investigate whether natural and viable flavor models can

We study the impact of an additional U(1)′ gauge symmetry with flavor-dependent charges for quarks and leptons on the LHC flavor anomalies observed in B→K∗μ+μ-, R(K)=B→Kμ+μ-/B→Ke+e-, and h→μτ. In its
