Unitary evolution from pure initial states to pure final states in pi(-)p->pi(-)pi(+)n imposes constraints on pion production amplitudes that are violatedby CERN data on polarized target at 17.2 GeV/c. The pion creation is anon-unitary process arising from a unitary co-evolution of the pion creationprocess with a quantum environment. The purpose of this work is to identify theinteracting degrees of freedom of the environment in a high resolutionamplitude analysis of CERN data on polarized target for dipion masses 580-1080MeV. The S-wave spectra |S|^2 show presence of rho0(770) while P-wave spectra|L|^2 show a dip at f0(980) mass. The observed rho0(770)-f0(980) mixing isencoded in all measured density matrix elements which also encode a levelsplitting of the spectra arising from the interaction of the pion creationprocess with the environment. The analytical form of the level splittingreveals the existence of a new quantum number characterizing the environment.We propose a model for the CPT violating interaction of the pion creationprocess with the environment in which non-diagonal transitions between resonantqqbar modes and pi(-)pi(+) states lead to vector-scalar mixing and a dynamicentanglement of the pi(-)pi(+) isospin states. The final states pi(-)p(+)n donot posses CPT cojugate states and the concept of CPT symmetry looses itsmeanining.
