FLAG review 2021

Y Aoki, T Blum, G Colangelo, S Collins… - The European Physical …, 2022 - Springer
We review lattice results related to pion, kaon, D-meson, B-meson, and nucleon physics with
the aim of making them easily accessible to the nuclear and particle physics communities …

Review of semileptonic B anomalies

B Capdevila, A Crivellin, J Matias - The European Physical Journal Special …, 2024 - Springer
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 …

Test of lepton universality in beauty-quark decays

Nature Physics, 2022 - nature.com
The standard model of particle physics currently provides our best description of
fundamental particles and their interactions. The theory predicts that the different charged …

[HTML][HTML] New physics in rare B decays after Moriond 2021

W Altmannshofer, P Stangl - The European Physical Journal C, 2021 - Springer
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\(R_K\) …

Tests of Lepton Universality Using and Decays

R Aaij, ASW Abdelmotteleb, C Abellán Beteta… - Physical review …, 2022 - APS
Tests of lepton universality in B 0→ KS 0 ℓ+ ℓ-and B+→ K*+ ℓ+ ℓ-decays where ℓ is either an
electron or a muon are presented. The differential branching fractions of B 0→ KS 0 e+ e …

To (b) e or not to (b) e: no electrons at LHCb

M Algueró, A Biswas, B Capdevila… - The European Physical …, 2023 - Springer
We discuss the impact of the recent LHCb update on the two lepton-flavour universality
ratios RK and RK∗, and the CMS update of B (B s→ μ+ μ-) regarding the possibility of New …

Rare b decays meet high-mass Drell-Yan

A Greljo, J Salko, A Smolkovič, P Stangl - Journal of High Energy Physics, 2023 - Springer
A bstract Rare b hadron decays are considered excellent probes of new semileptonic four-
fermion interactions of microscopic origin. However, the same interactions also correct the …

Reading the footprints of the B-meson flavor anomalies

C Cornella, DA Faroughy, J Fuentes-Martin… - Journal of High Energy …, 2021 - Springer
A bstract Motivated by the recent LHCb announcement of a 3. 1σ violation of lepton-flavor
universality in the ratio RK= Γ (B→ Kμ+ μ−)/Γ (B→ Ke+ e−), we present an updated …

Measurement of -Averaged Observables in the Decay

R Aaij, C Abellán Beteta, T Ackernley, B Adeva… - Physical review …, 2020 - APS
An angular analysis of the B 0→ K* 0 (→ K+ π-) μ+ μ-decay is presented using a dataset
corresponding to an integrated luminosity of 4.7 fb-1 of pp collision data collected with the …

Angular Analysis of the Decay

R Aaij, CA Beteta, T Ackernley, B Adeva, M Adinolfi… - Physical Review Letters, 2021 - APS
We present an angular analysis of the B+→ K*+(→ KS 0 π+) μ+ μ-decay using 9 fb-1 of pp
collision data collected with the LHCb experiment. For the first time, the full set of CP …
