Abstract:

We report a study of the decay Bs0鈫扗s(*)Ds(*) using a data sample corresponding to 1.3fb-1 of integrated luminosity collected by the D0 experiment in 2002-2006 during run II of the Fermilab Tevatron collider. One Ds(*) meson was partially reconstructed in the decay Ds鈫 渭谓, and the other Ds(*) meson was identified using the decay Ds鈫 蟺 where no attempt was made to distinguish Ds and Ds* states. For the branching fraction Br(Bs0鈫扗s(*)Ds(*)) we obtain a 90% C.L. range [0.002,0.080] and central value 0.039-0.017+0.019(stat)-0.015+0.016(syst). This was subsequently used to make the most precise estimate of the width difference 螖螕sCP in the Bs0-B虅s0 system: 螖螕sCP/ 螕s=0.079-0.035+0.038(stat)-0.030+0.031(syst). 漏 2007 The American Physical Society.

Abstract:

The first observation of (anti)deuterons in deep inelastic scattering at HERA has been made with the ZEUS detector at a centre-of-mass energy of 300-318 GeV using an integrated luminosity of 120 pb-1. The measurement was performed in the central rapidity region for transverse momentum per unit of mass in the range 0.3 < pT / M < 0.7. The particle rates have been extracted and interpreted in terms of the coalescence model. The (anti)deuteron production yield is smaller than the (anti)proton yield by approximately three orders of magnitude, consistent with the world measurements. 漏 2007 Elsevier B.V.
