We study ππ correlations in the exclusive reactions p p → 2π + 2π − and p p → 2π + 2π − π 0 at rest with complete reconstruction of the kinematics for each event. A new analysis technique has been developed which is model independent.

We study ππ correlations in the exclusive reaction pp → 2π+2π− at rest measured by the CPLEAR experiment. Avoiding the introduction of an arbitrary reference sample, we analyse differential distributions for equal charge pion pairs removing t

Atomic cascade in muonic hydrogen and the problem of kinetic-energy distribution in the ground state

Autor: V.E. Markushin

Publikováno v: Physical Review A. 50:1137-1143

The deexcitation of [mu][ital p] and [mu][ital d] atoms has been simulated within a kinetics model, taking the energy dependence of cascade processes into account. The x-ray yields and the kinetic-energy distributions for the ground and excited state

The radiative decay phi - gamma pi pi in a coupled channel model and the structure of f0(980)

Autor: V.E. Markushin

A coupled channel model is used to study the nature of the scalar mesons produced in the decay phi - gamma pi pi. The KKbar molecular picture of f0(980) is found to be in a good agreement with the recent experimental data from SND and CMD-2. The stru
