Entropy production by resonance decays.

We investigate entropy production for an expanding system of particles and resonances with isospin symmetry { in our case pions and mesons { within the framework of relativistic kinetic theory. A cascade code to simulate the kinetic equations is developed and results for entropy production and particle spectra are presented.

Excited Baryon Production and Decays

We consider decays of the lowest-lying positive parity (56-plet) and negative parity (70-plet) excited baryons. For the 70-plet, we include both single-quark and two-quark decay operators, and find, somewhat mysteriously, that the twoquark operators are not phenomenologically important. Studies of decays 70 → ∆+γ may strengthen or vitiate this observation. For the 56-plet decays, now using only...

Prompt Charmonium Production in Z Decays

The color-evaporation model quantitatively describes all data on photoproduction and hadroproduction of charmonium. Although the model is in part nonperturbative, the associated parameters can for instance be determined from the charmonium photoproduction data. At this point its predictions for the prompt production of ψ’s at the Z pole are made with no free parameters. We show here that this a...

Quarkonium production in SM Higgs decays

We investigate the SM Higgs decays into heavy quarkonia J/ψ and Υ in both color-singlet and color-octet mechanisms. It is found that in J/ψ production the contribution through color-octet processes overwhelm that in color-singlet processes all the intermediate region MZ < MH0 < 2Mw and the fraction ratio is comparatively large, but in Υ production the contribution through color-octet mechanism ...

Quarkonium Decays and Production in NRQCD

Some examples of the most recent applications of the NRQCD factorization approach to quarkonium phenomenology are presented. In the first part of the talk the NLO calculations for χcJ and Υ decays rates are compared to the data and the results critically analyzed. In the second part, I show how information on the non-perturbative matrix elements can be extracted from the hadronic fixed-target e...
