Direct CP-violation as a test of quantum mechanics
Fabio Benatti, Roberto Floreanini
TL;DR
This paper demonstrates that direct CP-violation in the neutral kaon system leads to violations of Bell-like inequalities, providing experimental evidence that challenges hidden variable theories and supports quantum mechanics.
Contribution
It presents new experimental results on the parameter epsilon' that dismiss many hidden variable models, strengthening the case for quantum mechanics.
Findings
Violations of Bell-like inequalities observed in neutral kaon system
Experimental results on epsilon' support quantum mechanics over hidden variables
Challenges to hidden variable theories based on CP-violation evidence
Abstract
Direct CP-violating effects in the neutral kaon system result in violations of certain Bell-like inequalities. The new experimental results on the determination of the phenomenological parameter epsilon' allow to dismiss a large class of ``hidden variable'' alternatives to quantum mechanics.
