AN EXTENDED VECTOR DOMINANCE MODEL : ITS IMPLICATIONS ON MESON DECAYS AND e+ e- ANNIHILATION INTO HADRONS
The consequences of the existence of new vector mesons are discussed. The decays w, V ) -+ 3 n, w, a, -+ no y, no, q, q' 3 yy, z, n' + z+ ny are studied taking into account the contributions of the p' (m,. 2: 1.5 GeV, T',, 2: 0.350 GeV) and its SU(3) partners. This allows an estimate of the p'-photon coupling and the coupling constants among the different SU(3) multiplets involved in the model....
متن کاملDIFFERENTIAL DISPERSIVE ANALYSIS OF e - PLUS e - MINUS ANNIHILATION INTO HADRONS
Using the natural differential dispersive character of the renormalization group, we give a possible explanation of the present high energy data for e+ehadrons. *Work supported in part by the U.S. Atomic Energy Commission.
متن کاملBose-Einstein correlations in a space-time approach to ee annihilation into hadrons
A new treatment of Bose-Einstein correlations is incorporated in a space-time parton-shower model for ee annihilation into hadrons. Two alternative algorithms are discussed, and we use a simple calculable model to demonstrate that they reproduce successfully the size of the hadron emission region. One of the algorithms is used to calculate two-pion correlations in e1e2→Z0→hadrons and e1e2→W1W2→...
متن کاملKNO scaling in processes of electron - positron annihilation to hadrons
The charged particles multiplicity distribution in the KNO form is discussed in processes of ee annihilation at energies √ s 14 – 206.2 GeV. The experimental data are compared to data, obtained with Monte Carlo simulation in PYTHIA in the Lund quark string model. It is shown, that both experimental and simulated data are described by the same distribution function in the KNO form. It is shown, ...
متن کاملNeutralino annihilation into gluons.
We present a complete calculation of the cross section for neutralino annihilation into the two-gluon final state. This channel can be quite important for the phenomenology of neutralino annihilation due to the well-known helicity suppression of neutralino annihilation into light quarks and leptons. In addition, we calculate the cross section for annihilation of neutralinos into a gluon and qua...
