Using the recent CERN and Fermilab measurements for J/ψ production by π±, K±, p, and p
beams we show, within the framework of quantum chromodynamics, that only a combined …

Inclusive J/ψ and ψ (2S) production has been studied in pp collisions at√ s= 1.8 TeV using
2.6±0.2 pb− 1 of data taken with the Collider Detector at Fermilab. The products of …

Abstract The observation of ϒ (9.5) suggests that the-onium of at least one new quark has
been discovered. We discuss the production and decays of the lowest-lying vector states …

The χ1++ (3507) and the χ2++ (3553) states have been observed in the Goliath
spectrometer at the CERN SPS in 185 GeV/cπ−-Be collisions. Their radiative decays …

We estimate the cross section for charmed particle production in proton-proton scattering. An
analysis of all possible sources of charmed particles reveals that the dominant mechanism …

We consider the hadronic production of heavy-quark bound states (QQ) and also associated
production of pairs of hadron containing heavy quarks (Qq+ q Q). Calculations of total cross …

Within the framework of perturbative QCD, we investigate the hadroproduction of charmed
particles via two-gluon as well as quark-pair annihilation. The total production cross section …

The inclusive production of electron pairs with and without additional photons was
measured at the CERN Intersecting Storage Rings (ISR). The investigation of J ψ particles …

As a part of the study of the inclusive production of electron pairs in pp collisions at the
CERN Intersecting Storage Rings (ISR), a search has been performed for additional photons …

We use the technique of averaging low-order quantum-chromodynamics diagrams over the
range from quark threshold to meson threshold to compute the photoproduction of ψ and ϒ …
