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” …

The past decades witnessed the golden era of hadron physics. Many excited open heavy
flavor mesons and baryons have been observed since 2017. We shall provide an updated …

The Review summarizes much of particle physics and cosmology. Using data from previous
editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average …

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 …

A simultaneous analysis of the B+→ K+ ℓ+ ℓ-and B 0→ K* 0 ℓ+ ℓ-decays is performed to test
muon-electron universality in two ranges of the square of the dilepton invariant mass, q 2 …

Conventional, hadronic matter consists of baryons and mesons made of three quarks and a
quark–antiquark pair, respectively,. Here, we report the observation of a hadronic state …

Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

Lepton scattering is an established ideal tool for studying inner structure of small particles
such as nucleons as well as nuclei. As a future high energy nuclear physics project, an …

An amplitude analysis of B-→ J/ψ Λ p¯ decays is performed using 4400 signal candidates
selected on a data sample of pp collisions recorded at center-of-mass energies of 7, 8, and …

An exotic narrow state in the $ D^ 0D^ 0\pi^+ $ mass spectrum just below the $ D^{*+} D^ 0$
mass threshold is studied using a data set corresponding to an integrated luminosity of 9 fb …
