Oscillations of neutral B mesons systems

TL;DR

This paper reviews the established phenomenon of neutral B meson oscillations, summarizing recent experimental results and current world averages for oscillation frequencies from multiple collider experiments.

Contribution

It provides a comprehensive review of recent measurements of B meson oscillations, including world averages and experimental limits from LEP, Fermilab, and SLAC.

Findings

World average of d = 0.471 b1 0.016 ps

Lower limit on s > 12.4 ps at 95% CL

Oscillation phenomenon in neutral B mesons is well established

Abstract

The oscillation phenomenon in the neutral B mesons systems is now well established. The motivations and principles of the measurements are given; then the most recent results from the LEP experiments, the CDF collaboration at Fermilab and the SLD collaboration at SLAC are reviewed. The present world average of the $\bd$ meson oscillation frequency is $\dmd = 0.471 \pm 0.016 \ps$ and the lower limit on the $\bs$ oscillation frequency is $\dms > 12.4 \ps at 95% CL$.
