Specialized data-taking and data-processing techniques were introduced by the CMS
experiment in Run 1 of the CERN LHC to enhance the sensitivity of searches for new …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

This paper reports world averages of measurements of b-hadron, c-hadron, and τ-lepton
properties obtained by the Heavy Flavor Averaging Group using results available before …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

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\(R_K\) …

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 …

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 …

A bstract A search is presented for physics beyond the standard model (SM) using electron
or muon pairs with high invariant mass. A data set of proton-proton collisions collected by …

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 …

A bstract We present a global interpretation of Higgs, diboson, and top quark production and
decay measurements from the LHC in the framework of the Standard Model Effective Field …
