Study of the Process $e^+e^- \to K^0_L K^0_S$ in the C.M.Energy Range 1.05-1.38 GeV with CMD-2

TL;DR

This study measures the cross section of the process e+e- to K0L K0S in the 1.05-1.38 GeV energy range, revealing higher values than predicted by known meson contributions, indicating possible additional effects.

Contribution

First detailed measurement of e+e- to K0L K0S cross section in this energy range showing deviations from standard meson models.

Findings

Cross section exceeds expectations from rho, omega, phi meson contributions.

Results suggest additional dynamics or resonances beyond known mesons.

Data provides new insights into kaon pair production in e+e- collisions.

Abstract

The process $e^+e^- \to K^0_L K^0_S$ has been studied with the CMD-2 detector using about 950 events detected in the center-of-mass energy range from 1.05 to 1.38 GeV. The cross section exceeds the expectation based on the contributions of the rho(770), omega(782) and phi(1020) mesons only.
