We review the theoretical and phenomenological aspects of the Next-to-Minimal
Supersymmetric Standard Model: the Higgs sector including radiative corrections and the 2 …

Dramatic progress has been made over the last decade in the numerical study of quantum
chromodynamics (QCD) through the use of improved formulations of QCD on the lattice …

The B-factories and Large Hadron Collider experiments have demonstrated the ability to
observe and measure the properties of bottomonium mesons. In order to discover missing …

We extend our earlier lattice-QCD analysis of heavy-quark correlators to smaller lattice
spacings and larger masses to obtain new values for the c mass and QCD coupling, and, for …

The bottomonium spectrum is computed in dynamical 2+ 1 flavor lattice QCD, using
nonrelativistic QCD for the b quarks. The main calculations in this work are based on gauge …

We review weakly-bound heavy quarkonium systems using effective field theories of QCD.
We concentrate on potential non-relativistic QCD, which provides with a well founded …

We have performed a search for the η b (1 S) meson in the radiative decay of the Υ (2 S)
resonance<? format?> using a sample of 91.6× 10 6 Υ (2 S) events recorded with the …

We search for a light Higgs boson A 0 in the radiative decay Υ (3 S)→ γ A 0, A 0→ τ+ τ-, τ+→
e+ ν e ν¯ τ, or τ+→ μ+ ν μ ν¯ τ. The data sample contains 122× 10 6 Υ (3 S) events recorded …

The bottomonium spectrum is far from being established. The structures of higher vector
states, including the ϒ (10580), ϒ (10860), and ϒ (11020) states, are still in dispute. In …

Using a sample of 771.6× 10 6 ϒ ϒ (4 S) decays collected by the Belle experiment at the
KEKB e+ e-collider, we observe, for the first time, the transition ϒ (4 S)→ η hb (1 P) with the …
