Single-diffractive cross sections in pp and pbar p collisions are described by a three-parameter fit in a dephasing Lindblad framework yielding a consistent decoherence factor φ ≈ 0.89 that favors CPT-invariant dephasing over CP-invariant.

abstract
The analysis conducted in this work indicates that interactions of a CP-violating (and CPT-preserving) quantum system with a thermodynamic environment can produce the impression of a CPT violation in the system. This conclusion is reasonably consistent with the results reported for decays of neutral K-mesons.

Decoherence, Perturbations and Symmetry in Lindblad Dynamics -- Implications for Diffractive Dissociation
Single-diffractive cross sections in pp and pbar p collisions are described by a three-parameter fit in a dephasing Lindblad framework yielding a consistent decoherence factor φ ≈ 0.89 that favors CPT-invariant dephasing over CP-invariant.
