Calculation Results

To describe [Formula: see text] interactions with production of three [Formula: see text]-particles at incident neutron kinetic energy of 14 MeV in a nuclear (photo) emulsion, a Monte Carlo model is proposed for four channels of decay of an excited carbon-12 nucleus into three [Formula: see text]-particles. The Monte Carlo calculation results describe well the experimental data on the distribution of the angle between the three-dimensional momenta of all pairs of [Formula: see text]-particles in a collision event, on the distribution of the angle between the projections of the momentum vectors of all pairs of [Formula: see text]-particles in collision event on each of the coordinate planes, on the distribution of the sum of the kinetic energies of all pairs of [Formula: see text]-particles in a collision event, and the distribution of projections of the momenta of [Formula: see text]-particles on the coordinate planes. The best agreement of the Monte Carlo model results with the experimental data is achieved if the direct decay [Formula: see text] and decay through the formation of an intermediate beryllium nucleus [Formula: see text] are generated with equal probabilities, while the excitation energies of 3.04 MeV, 1.04 MeV, and 0.1 MeV for the beryllium nucleus are generated with relative weights of 75%, 15%, and 10%, respectively.

CHARGE STRUCTURE IN THE Z0 AS A POSSIBLE ORIGIN OF RARE DECAYS Z0→l+l−γγ

Quantitative Results

The possible rare direct decay Z0→l+l−γγ is a sensitive probe of structure in the Z0. It is possible that there is a mass distribution in high Mγγ, the invariant mass of two photons, which arises from structure in the Z0. This would lead to events with high Mγγ, over and above those that arise from bremsstrahlung. We find that such events could become evident when the data exceed about four million Z0 decays. We present quantitative results for the double distribution in the invariant masses, Mγγ and Mlī, and for the distribution in Mγγ. In the double distributions, Mγγ>45 GeV with Miī<35 GeV is favored.
