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 …

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 …

This report describes the physics case, the resulting detector requirements, and the evolving
detector concepts for the experimental program at the Electron-Ion Collider (EIC). The EIC …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

The super τ-charm facility (STCF) is an electron–positron collider proposed by the Chinese
particle physics community. It is designed to operate in a center-of-mass energy range from …

The quark model was formulated in 1964 to classify mesons as bound states made of a
quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all …

A bstract Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-
energy extensions of the Standard Model (SM). We investigate the phenomenology of an …

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 search for charge-parity (CP) violation in D 0→ K-K+ and D 0→ π-π+ decays is reported,
using pp collision data corresponding to an integrated luminosity of 5.9 fb-1 collected at a …

We search for single-photon events in 53 fb-1 of e+ e-collision data collected with the
BABAR detector at the PEP-II B-Factory. We look for events with a single high-energy photon …
