Antonio Di Domenico
TL;DR
This paper discusses tests of CPT symmetry and quantum mechanics using entangled neutral kaons at a phi-factory, with current results showing no deviations and future experiments aiming for higher precision at the Planck scale.
Contribution
It reports on the latest experimental tests of CPT symmetry in neutral kaons and the potential for future high-precision measurements at a phi-factory.
Findings
No deviation from quantum mechanics or CPT symmetry observed.
Measurements reach the Planck-scale sensitivity.
Upgraded detector aims to improve test precision.
Abstract
The neutral-kaon system constitutes a fantastic and unique laboratory for the study of CPT symmetry and the basic principles of quantum mechanics, and a -factory represents a unique opportunity to push forward these studies. The experimental results show no deviation from the expectations of quantum mechanics and CPT symmetry, while the extreme precision of the measure- ments, in some cases, reaches the interesting Planck-scale region. At present the KLOE-2 experiment is collecting data with an upgraded detector with the aim of significantly improving these kinds of experimental tests.
