We review the present status of the Standard Model calculation of the anomalous magnetic
moment of the muon. This is performed in a perturbative expansion in the fine-structure …

Dark matter represents currently an outstanding problem in both cosmology and particle
physics. In this review we discuss the possible explanations for dark matter and the …

In a study of B+→ J/ψ γ K+ decays, we find evidence for the radiative decay X (3872)→ J/ψ γ
with a statistical significance of 3.4 σ. We measure the product of branching fractions B (B+→ …

We present updated measurements of time-dependent CP asymmetries in fully
reconstructed neutral B decays containing a charmonium meson. The measurements …

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” …

A large number of experimental discoveries especially in the heavy quarkonium sector that
did not meet the expectations of the until then very successful quark model led to a …

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 …

This paper describes the algorithms for the reconstruction and identification of electrons in
the central region of the ATLAS detector at the Large Hadron Collider (LHC). These …

The top quark mass is one of the most intriguing parameters of the standard model (SM). Its
value indicates a Yukawa coupling close to unity, and the resulting strong ties to Higgs …

The discrepancy between the Standard Model theory and experimental measurement of the
muon magnetic moment anomaly, a μ=(g μ-2)/2, is connected to precision electroweak (EW) …
