The origin of the transmission damage in PWO crystals is discussed. It is shown that both electron and hole centers created on the basis of structural defects in PbWO4 crystals contributed to the induced absorption of the crystals. The different aspects of the suppression of the recharge processes in PWO scintillation crystals are also discussed. 1 Bogoroditsk Techno Chemical Plant, Bogoroditsk...

Using a relativistic constituent quark model based on point form of relativistic quantum mechanics with given set of degrees of freedom we investigate electroweak decays of the pion and ρ mesons. All free parameters of quark model (the mass u(d) -quark and parameters which determines the confinement scale) are fixed by using relevant experimental data. Leptonic Decays of Mesons in a PoincareCov...
