Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

We review the current status and implications of the anomalies (ie deviations from the
Standard Model predictions) in semi-leptonic B meson decays, both in the charged and in …

A bstract There are two tensions related to the Cabibbo angle of the CKM matrix. First, the
determinations of V us from K μ2, K ℓ3, and τ decays disagree at the 3σ level. Second, using …

Measurements of the branching ratios of B→ D (*) τ ν¯/B→ D (*) ℓ ν¯ and B c→ J/ψ τ ν¯/B
c→ J/ψ ℓ ν¯ by the BABAR, Belle and LHCb collaborations consistently point towards an …

We explore the possibility that an SU (2) L triplet scalar with hypercharge Y= 0 is the origin of
the 95 GeV diphoton excess. For a small mixing angle with the Standard Model Higgs, its …

The combination of precise determinations of V us and V ud hints toward a violation of the
Cabibbo-Kobayashi-Maskawa matrix first row unitarity at about 3 σ level. Conversely, the …

A bstract Leptoquarks are prime candidates for explaining the intriguing hints for lepton
flavour universality violation. In particular, the SU (2) L doublet of scalar leptoquarks S 2 is …

The standard model (SM) of particle physics is the mathematical description of the
fundamental constituents and interactions of matter. Its last missing particle, the Higgs …

In recent years, several hints for new scalar particles have been observed by the Large
Hadron Collider at CERN. In this context, we recast and combine the CMS and ATLAS …

In this article, we propose the Δ 2 HDM S as a combined explanation of several excesses
and anomalies observed at the LHC. Especially, tt¯ differential distributions point towards …
