“Spooky Action At Distance” In Particle Physics?!
Physicists have developed the first conclusive test to better understand high-energy particles correlations.
Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as ℠Bell´s nonlocality.´ This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called ℠CP violation´ principle, which is used to explain the dominance of matter over antimatter. These findings by Beatrix Hiesmayr, a theoretical physicist at the University of Vienna, and her colleagues, a team of quantum information theory specialists, particle physicists and nuclear physicists, have been published in EPJ C´.
In this study, the authors have succeeded in devising a new Bell test, taking into account the decay property of high-energy particles systems, called kaon-antikaon systems. This procedure ensures that the test is conclusive — a goal that has never before been achieved — and simultaneously guarantees its experimental testability. Experimental testing requires equipment such as the KLOE detector at the accelerator facility DAPHNE in Italy.
Revealing “spooky action at distance” for kaon-antikaon pairs has fundamental implications for our understanding of such particles´ correlations and could ultimately allow us to determine whether symmetries in particle physics and manifestations of particles correlations are linked.
