Study of the Decoherence of Entangled Kaons by the Interaction with Thermal Photons

Abstract

The KLOE-2 detector is a powerful tool to study the temporal evolution of quantum entangled pairs of kaons. The accuracy of such studies may in principle be limited by the interaction of neutral kaons with thermal photons present inside the detector. Therefore, it is crucial to estimate the probability of this effect and its influence on the interference patterns. In this paper we introduce the phenomenology of the interaction of photons with neutral kaons and present and discuss the obtained quantitative results.Comment: Proceeding from 2nd Young Researchers Workshop: Physics Challenges in the LHC Era, Frascati, May 10 and 13, 2010; 6 pages, 4 figure
