Charmonium Decays of Y (4260), ψ(4160), and ψ(4040)
Using data collected with the CLEO detector operating at the CESR e+e− collider at √ s = 3.974.26GeV, we investigate 15 charmonium decay modes of the ψ(4040), ψ(4160), and Y (4260) resonances. We confirm, at 11σ significance, the BaBar Y (4260)→ π+π−J/ψ discovery, make the first observation of Y (4260) → π0π0J/ψ (5.1σ), and find the first evidence for Y (4260) → K+K−J/ψ (3.7σ). We measure e+e− ...
متن کاملQuark model description of the NN ∗ ( 1440 ) potential
We derive a NN * (1440) potential from a non-relativistic quark-quark interaction and a chiral quark cluster model for the baryons. By making use of the Born-Oppenheimer approximation we examine the most important features of this interaction in comparison to those obtained from meson-exchange models.
متن کاملpQCD Calculations of Heavy Quark and J/ψ Production
We review the present status of theoretical predictions for both closed (J/ψ) and open heavy quark production in high energy collisions, and their comparisons to experimental data.
متن کاملΩ, J/ψ and ψ′ Production in Nuclear Collisions and Quark Gluon Plasma Hadronization
The transverse mass spectra of Ω, J/ψ and ψ in Pb+Pb collisions at 158 A·GeV are studied within a hydrodynamical model of the quark gluon plasma expansion and hadronization. The model reproduces the existing data with the common hadronization parameters: temperature T = Tc ∼= 170 MeV and average collective transverse velocity vT ∼= 0.2. The possibility of observing the quark gluon plasma (QGP) ...
