Measurement of the mass difference m(B-0)-m(B+)
No full textUsing 230 x 10(6) B (B) over bar events recorded with the BABAR detector at the e(+)e(-) storage rings PEP-II, we reconstruct approximately 4100 B-0 -> J/psi K+pi(-) and 9930 B+ -> J/psi K+ decays with J/psi -> mu(+)mu(-) and e(+)e(-). From the measured B-momentum distributions in the e(+)e(-) rest frame, we determine the mass difference m(B-0) - m(B+) = (+0.33 +/- 0.05 +/- 0.03) MeV/c(2)

Measurement of the mass difference m(B0)-m(B+)
No full textUsing 230×106 BB̄ events recorded with the BABAR detector at the e+e- storage rings PEP-II, we reconstruct approximately 4100 B0→J/ψK+π- and 9930 B+→J/ψK+ decays with J/ψ→μ+μ- and e+e-. From the measured B-momentum distributions in the e+e- rest frame, we determine the mass difference m(B0)-m(B+)=(+0. 33±0.05±0.03)MeV/c2. © 2008 The American Physical Society
Dim A Distributed Information Management System For The Delphi Experiment At Cern
No full textThe Online Control and Monitoring system of the DELPHI Experiment at LEP is distributed over around 20 VAX/VMS Systems and 70 FASTBUS processors. The DIM, Delphi Information Management System allows User Interfaces and Control processes to access information from any of these machines in a transparent way. Using DIM, Delphi User Interfaces can be run anywhere in the world provided that DECNET or TCP-IP are available. I. Introduction DELPHI (DEtector with Lepton, Photon and Hadron Identification) [1] is one of the four experiments built for LEP (Large Electron-Positron collider) at CERN . It consists of a central cylindrical section and two end-caps. The overall length and the diameter are over 10 meters and the total weight is 2500 tons. The electron-positron collisions take place inside the vacuum pipe in the centre of DELPHI and the products of the annihilations fly radially outwards. The products of the annihilations are "tracked" by several layers of detectors and read out via so..

Architectural Fictions
No full textArchitectural Fictions was a curatorial project that brought together the work of eight artist that in different ways addressed principles of fictioning and narrative in relation to the built environment. The project brought critical focus to the narrative structures implicit in the production of space. Through dialogue with the participants, the project developed speculative critical exchange, examining questions such as the interplay between the real and the virtual and the role of design in relation to processes of habitation. Architectural Fictions formed a keynote exhibition in South Hill Park Arts Centre program. SHP is funded by the Arts Council England and is in partnership with ARC which delivers events by professionals from the field of art and culture.
A public lecture about Architectural Fictions was delivered by Mary Maclean and Tim Renshaw who together make up the group Outside Architecture.
Outside Architecture aims to open up speculative dialogues and images on the materials and signs that compose the texture of shared and lived in spaces
