At the present time (2022), there are discrepancies with the predictions of the Standard
Model in several observables involving b→ s ℓ+ ℓ− and decays. These are the B flavor …

The anomalies in rare B decays endure. We present results of an updated global analysis
that takes into account the latest experimental input–in particular the recent results on\(R_K\) …

The LHCb Collaboration has recently released a new study of B+→ K+ ℓ+ ℓ-and B→ K* 0 ℓ+
ℓ-(ℓ= e, μ) decays, testing lepton universality with unprecedented accuracy using the whole …

An improved measurement of the decay B s 0→ μ+ μ-and searches for the decays B 0→ μ+
μ-and B s 0→ μ+ μ-γ are performed at the LHCb experiment using data collected in proton …

Motivated by renewed evidence for new physics in b→ s ℓ ℓ transitions in the form of LHCb's
new measurements of theoretically clean lepton-universality ratios and the purely leptonic B …

Following the updated measurement of the lepton flavour universality (LFU) ratio R_K RK in
B → K ℓ ℓ B→ K ℓ ℓ decays by LHCb, as well as a number of further measurements, eg R …

Recently the LHCb collaboration has confirmed the evidence for lepton flavour
nonuniversality at the 3.1σ level via an updated measurement of R K. In this work we …

We evaluate the impact of radiative corrections in the ratios Γ B → M μ^+ μ^-/Γ B → M e^+ e^-
Γ B→ M μ+ μ-/Γ B→ M e+ e-when the meson M is a K or a K^* K∗. Employing the cuts on m …

A bstract The gauge-invariant operators up to dimension six in the low-energy effective field
theory below the electroweak scale are classified. There are 70 Hermitian dimension-five …
