Decoherence, perturbations and symmetry in Lindblad dynamics: implications for diffractive dissociation

Puntos clave

The study aims to extend the application of Lindblad dynamics to analyze decoherence and symmetry in diffractive dissociation.
Developed a perturbative Dyson-type treatment within a dephasing Lindblad framework.
Analyzed single and double diffractive data in proton and antiproton collisions.
Applied a three-parameter fit to experimental cross-section data.
Single-diffraction cross sections achieved a relative RMS deviation of approximately 4%.
The extracted decoherence factor was consistently estimated as phi ≈ 0.89 across various experimental data.
The findings suggest phi = 1 for CP-invariant dephasing and phi < 1 for CPT-invariant, favoring the latter interpretation.

Resumen

Abstract We extend a perturbative Dyson-type treatment and discrete-symmetry constraints from the Schrödinger and von Neumann equations to a dephasing Lindblad framework. This work develops further the odd-symmetric formulation involving dual temporal conditions from general dynamical considerations to specific tools of quantum mechanics. Applying the resulting scaling relations to published single- and double-diffractive data in pp and pp p p ¯ collisions (ISR, UA4, UA5, CDF, D0, ALICE, and E710), we show that single-diffraction cross sections are well described by a three-parameter fit with a relative RMS deviation of 4\%, ∼ 4 %, substantially improving upon conventional approximations that neglect decoherence. The extracted decoherence factor is consistently 0. 89, ϕ ≈ 0. 89, in agreement across SD, DD, and E710-based (direct) estimates, and is naturally interpreted as =1 ϕ = 1 for CP-invariant dephasing but ϕ 1 for CPT-invariant dephasing, favouring the latter.
