AbstractAbstract
[en] If any neutrinos have mass the reaction π0→γanti γ is allowed. With the forthcoming generation of machines this could provide a practical means for finding limits on neutrino masses. (Auth.)

AbstractAbstract
[en] The statistical system of π0, π+ and π- mesons with zero total isospin is studied. For neutral pions there is the enhancement of the fluctuations, whereas for charged pions the isospin conservation suppresses fluctuations. The correlations between the numbers of charged and neutral pions are observed for finite systems.

[en] Motivated by the discrepancy between theoretical predictions and present experimental data for the branching ratio of π0 → e+e- we propose a measurement of the electromagnetic pion form factor through the two-photon process e+e- → e+e-π0. (Author)

AbstractAbstract
[en] The Crystal Barrel experiment has been constructed and installed at the Low Energy Antiproton Ring (LEAR) at CERN. It has been fully operational since late 1989. In this talk, recent results of meson spectroscopy in bar pp annihilations are presented. The main emphasis is on all-neutral annihilations, the study of the strange quark content of the proton, and the investigation of the decay mode of η particles. A 2++ resonance decaying into π0π0 at a mass of 1515 ± 10 MeV, with a width of 120 ± 10 MeV, has been seen in a 3π0 final state. 14 refs., 18 figs

AbstractAbstract
[en] It is shown that in supersymmetric models with a light photino the probability of the decay π0→gammagamma can have a magnitude which presents interest from the point of view of experiment, provided that there is sufficiently large mixing between left-handed and right-handed scalar quarks
