Simulation and wavelet analysis of vector mesons in positron electron annihilation.

摘要

In the present paper I demonstrate the application of the wavelet analysis technique to resolving ρ′ meson states in simulated data of e+e − annihilation into hadrons (hadronic events). I have written a C++ program to carry out decomposition (wavelet transformation) of this data at different scales, to implement structure analysis (recognition of ρ ′ meson states) and to remove noise from the data leaving important structure parameters unchanged. The main purpose of this thesis work is to demonstrate the wavelet analysis of model signals and to work out a strategy for dealing with experimental data in the physics of resonances.
