B meson mixing at CDF II
Marco Rescigno (for the CDF collaboration)
TL;DR
This paper reports the first limit on Bs meson mixing frequency using Tevatron Run II data, setting a new constraint on Delta ms with a sensitivity of 8.4 ps^-1.
Contribution
It provides the first experimental limit on Bs mixing frequency from Tevatron Run II data, improving constraints on B meson oscillations.
Findings
Delta ms < 7.9 ps^-1 at 95% C.L.
Sensitivity of 8.4 ps^-1 achieved.
First limit on Bs mixing at Tevatron.
Abstract
We present the first limit on Bs mixing frequency obtained using 360 pb^-1 of Tevatron Run II data with the CDF II detector. We derive Delta ms 7.9 ps^-1 @ 95 % C.L. with a sensitivity of 8.4 ps^-1. -
