Measurement of Bd 0- Bd 0oscillations
, Zeitschrift Fur Physik C Particles and Fields, Vol: 76, Pages: 579-598, ISSN: 0170-9739B<inf>d</inf> <sup>0</sup>meson oscillations are measured in hadronic Z<sup>0</sup>decays using the charge of a lepton or the mean charge of an event hemisphere to sign the presence of a b or a b quark when it is produced, and using the charge of a lepton emitted at large p<inf>t</inf>or of a D<sup>∗±</sup>to sign the presence of a B or a B meson when it decays. With 3.2 million hadronic Z<sup>0</sup>decays registered by DELPHI between 1991 and 1994, the mass difference Δm<inf>d</inf>between the two physical B<inf>d</inf> <sup>0</sup>states is measured in four channels: Δm<inf>d</inf>= 0.523 ± 0.072 ± 0.043 ps<sup>-1</sup>(D<sup>∗±</sup>- Q<inf>hem</inf>) Δm<inf>d</inf>= 0.493 ± 0.042 ± 0.027 ps<sup>-1</sup>(ℓ - Q<inf>hem</inf>) Δm<inf>d</inf>= 0.499 ± 0.053 ± 0.015 ps<sup>-1</sup>((π<sup>∗</sup>- ℓ) - Q<inf>hem</inf>) Δm<inf>d</inf>= 0.480 ± 0.040 ± 0.051 ps<sup>-1</sup>(ℓ - ℓ). Taking into account the statistical overlap between these measurements and the common systematic uncertainties, the combined result is: Δm<inf>d</inf>= 0.497 ± 0.035 ps<sup>-1</sup>.

Diffractive production of ρ0(770) mesons in muon-proton interactions at 470 GeV
, Zeitschrift Fur Physik C Particles and Fields, Vol: 74, Pages: 237-261, ISSN: 0170-9739The diffractive production of ρ<sup>0</sup>(770) mesons in muon-proton interactions is studied in the kinematic region 0.15 GeV<sup>2</sup> < Q<sup>2</sup> < 20 GeV<sup>2</sup> and 20 GeV < v < 420 GeV. The data were obtained in the Fermilab fixed-target experiment E665 with primary muons of 470 GeV energy. Results are presented on the Q<sup>2</sup>, x and v dependence of the cross section, on the shape of the π<sup>+</sup>π<sup>-</sup> mass spectrum, on the slope of the diffraction peak and on the production and decay angular distributions of the ρ<sup>0</sup>(770). The cross section for diffractive production of ρ<sup>0</sup> by virtual photons on protons depends mainly on Q<sup>2</sup>. At fixed Q<sup>2</sup>, no significant dependence on x or v is observed. The extrapolation to Q<sup>2</sup> = 0 yields a photoproduction cross section of (10.30 ± 0.33) μb. The slope of the t′ distribution has a value of (7.0 ± 0.2) GeV<sup>-2</sup>, with a tendency to decrease as Q<sup>2</sup> increases. The production and decay angular distributions of the ρ<sup>0</sup> depend strongly on Q<sup>2</sup> and are consistent with s-channel helicity conservation. The ratio R = σ<inf>L</inf>/σ<inf>T</inf> deduced from the decay angular distributions rises strongly with Q<sup>2</sup>, passing the value of 1 at Q<sup>2</sup> ≈ 2 GeV<sup>2</sup>. © Springer-Verlag 1997.
