We discuss theoretical and phenomenological aspects of two-Higgs-doublet extensions of
the Standard Model. In general, these extensions have scalar mediated flavour changing …

Precise measurements of the lepton properties provide stringent tests of the Standard Model
and accurate determinations of its parameters. We overview the present status of τ physics …

The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a
success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a …

In the alignment limit of a multidoublet Higgs sector, one of the Higgs mass eigenstates
aligns with the direction of the scalar field vacuum expectation values, and its couplings …

The existence of charged Higgs boson (s) is inevitable in models with two (or more) Higgs
doublets. Hence, their discovery would constitute unambiguous evidence for new physics …

BABAR, Belle, and LHCb Collaborations report evidence for new physics in B→ D τ ν and
B→ D* τ ν of approximately 3.8 σ. There is also the long lasting discrepancy of about 3 σ in …

In this article, we perform an extensive study of flavor observables in a two-Higgs-doublet
model with generic Yukawa structure (of type III). This model is interesting not only because …

A bstract Flavor symmetries that explain masses and mixings of the standard model fermions
dictate flavor patterns for the couplings of scalar and vector leptoquarks to the standard …

Recently, the BABAR Collaboration reported the first evidence for new physics in B→ D τ ν
and<? format?> B→ D* τ ν. Combining both processes, the significance is 3.4 σ. This result …

A bstract We analyze the recent experimental evidence for an excess of τ-lepton production
in several exclusive semileptonic B-meson decays in the context of two-Higgs-doublet …
