D0-D∄0 mixing studies with the decays D0→KS0K∓π±

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 701:3 (2011) 353-356

Authors:

S Malde, G Wilkinson

Abstract:

We demonstrate how a time-dependent analysis of the decays D0→KS0K∓π± can be used to determine the D0-D∄0 mixing parameter y with a precision that is competitive with established methods. The proposed analysis is an inclusive study which makes use of the measurements of the coherence factor and mean strong phase difference for these decays recently performed by CLEO. © 2011 Elsevier B.V.

Abstract:

The $\bar{\Lambda} / \Lambda$ and $\bar{\Lambda} / K^0_\mathrm{S}$ production ratios are measured by the LHCb detector from $0.3\,\mathrm{nb}^{-1}$ of $pp$ collisions delivered by the LHC at $\sqrt{s} = 0.9$\,TeV and $1.8\,\mathrm{nb}^{-1}$ at $\sqrt{s} = 7$\,TeV. Both ratios are presented as a function of transverse momentum, $p_\mathrm{T}$, and rapidity, $y$, in the ranges {$0.15 < p_\mathrm{T} < 2.50\,\mathrm{GeV}/c$} and {$2.0
