Quark - Parton Model Predictions for Hadronic Charge Ratios in Incixsive Lipton - Induced Reactions

چکیده
We investigate the predictions of the quark par-ton model for hadronic charge ratios in the current fragmentation region in inclusive lepton-induced reactions. We use parton distribu'&-on functions given by McElhaney and Tuan from fits to single arm elastic electron scattering data, and we obtain relative parton fragmentation functions from a fit to the fl+/fi-ratio in electro-production from a proton target. The electroproduced n+/n' ratio from a neutron target is predicted to be 21.2 at moderate u) and ,' and <l at small a, providing a dramatic test of the model. The model gives a neutrino (anti-neutrino) produced fl*/fi-(~-/fi~) ratio of 3.0 f 0.6 from any target. Also the ratio of charged to neutral K production in e+e-annihilation should be 1.38 2 .lO.

Effective Hamiltonian of Electroweak Penguin for Hadronic b Quark Decays
In this research we work with the effective Hamiltonian and the quark model. We investigate the decay rates of matter-antimatter of quark. We describe the effective Hamiltonian theory and apply this theory to the calculation of current-current ( ), QCD penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. The gluonic penguin structure of hadronic decays is studied thro...

The gluonic penguin structure of hadronic decays ...
متن کاملA Transport Model for Heavy Ion Collisions at Rhic
To study heavy ion collisions at energies to be available from the Relativistic Heavy Ion Collider (RHIC), we have developed a transport model that includes both initial partonic and final hadronic interactions. Specifically, the parton cascade model ZPC, which uses as input the parton distribution from the HIJING model, is extended to include the quark-gluon to hadronic matter transition and a...
