[en] We present a summary of the results on electroweak asymmetries performed by the SLD experiment at the Stanford Linear Collider (SLC). Most of these results are final and are based, unless otherwise stated, on the full 1993-1998 data set of approximately 550,000 hadronic decays of Z⁰ bosons, produced with an average electron beam polarization of 73%

[en] The authors present a study of time-dependent asymmetries in neutral B meson decays collected with BaBar detector at the PEP-II asymmetric B Factory. They find a non-zero value for the CP-violating amplitude sin(2β) thus establishing CP violation in the B⁰ system at the 4.1σ level. They also report on precision measurements of the B⁺ and B⁰ lifetimes and of the B⁰(bar B)⁰ oscillation frequency Δm_d, and on a first measurement of the time-dependent CP-violating amplitude in B⁰ → π⁺π^- decays

[en] The CAST experiment is being mounted at CERN. It will make use of a decommissioned LHC test magnet to look for solar axions through its conversion into Photons inside the magnetic field. The magnet has a field of 9.6 Tesla and length of 10 m and is installed in a platform which allows to move it ±8 degrees vertically and ±40 degrees horizontally. According to these numbers we expect a sensitivity in axion-photon coupling g_aγγ ∼< 5 x 10^-11 GeV^-1 for m_a ∼< 10^-2 eV, and with a gas filled tube g_aγγ ∼< 10^-10 GeV^-1 for m_a ∼< 2 eV.

[en] Profiles of high-energy proton and antiproton beams of the CERN Proton Synchrotron Complex are monitored, so far, by a number of multiwire proportional chambers (MWPC) working under the integrated current mode of the sensitive wires. However, for very low energy particles, this standard method suffers from the absorption of the incident energy inside the gas-separating windows of the MWPCs. A solution is proposed here on the basis of a new photomultiplier technique. (orig.)

[en] A detailed examination of current data on S₁₇ (as opposed to an examination of S₁₇(0) only) excludes quoting S₁₇(0) with sufficiently small uncertainty. In contrast to suggestions that S₁₇(0) is now known with the accuracy of +/-3%, the exact value of S₁₇(0) is dependent on the choice of the data and the choice of theory used for extrapolation. In addition recent high precision results (including the Seattle data) on S₁₇ which are in good agreement, still differ on the measured slopes, as do theoretical models that predict different d-wave contribution, precluding an accurate extrapolation to zero energy of the consistent data. Using a common extrapolation of only the consistent high precision data, suggests a value of S₁₇(0)=21.2+/-0.5 eV-b, but a value equal to or smaller than 19.0 eV-b can not be excluded due to the uncertainty in the extrapolation, leading to an additional error of _-3.0^+0.0 eV-b. This (unacceptable) situation must be cleared by future experiments

[en] The Majorana experiment[nucl-ex/0311013] is a proposed ⁷⁶Ge-based search for neutrinoless double-beta (0νββ) decay and dark matter (DM). It will use segmented, enriched germanium detectors in a close-pack configuration. With 500 kg of germanium, Majorana would be expected to reach a sensitivity to the 0νββ decay half-life of 10²⁷ years, corresponding to a neutrino mass near the atmospheric mass scale. Current development efforts are presented, along with performance expectations and background reduction methods. Additionally, the status of the related detectors SEGA (Segmented Enriched Germanium Assembly) and MEGA [Kazkaz, K., Aalseth, C.E., Hossbach, T.W., Gehman, V.M., Kephart, J.D., Miley, H.S., IEEE Trans. Nuc. Sci. 51 (2004) 1029] (Multi-Element Gamma Assay) are presented. Current simulation efforts will be presented in a parallel poster by Reyco Henning

[en] This paper describes the forthcoming enlargement of the Canfranc Underground Laboratory (LSC) which will allow to host new international Astroparticle Physics experiments and therefore to broaden the European underground research area. The new Canfranc Underground Laboratory will operate in coordination (through the ILIAS Project) with the Gran Sasso (Italy), Modane (France) and Boulby (UK) underground laboratories
