Search for Darkonium in $e^+e^-$ Collisions
/ BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

A new $G$-parity violating amplitude in the $J/\psi$ decay?
/ Ferroli, R. Baldini (Frascati) ; De Mori, F. (INFN, Turin ; Turin U.) ; Destefanis, M. (INFN, Turin ; Turin U.) ; Maggiora, M. (INFN, Turin ; Turin U.) ; Pacetti, S.

The $J/\psi$ meson has negative $G$-parity so that, in the limit of isospin conservation, its decay into $\pi^+\pi^-$ should be purely electromagnetic. However, the measured branching fraction $\mathcal{B}(J/\psi\to\pi^+\pi^-)$ exceeds by more than 3.9 standard deviations the expectation computed according to BaBar data on the $e^+e^-\to\pi^+\pi^-$ cross section.

Unexpected features of $e^{+}e^{-} \to p\overline{p}$ and $e^{+}e^{-} \to \Lambda\overline{\Lambda}$ cross sections near threshold
/ Baldini, Rinaldo (Enrico Fermi Ctr., Rome ; Frascati) ; Pacetti, Simone (Enrico Fermi Ctr., Rome ; Frascati) ; Zallo, Adriano (Frascati) ; Zichichi, Antonino (Enrico Fermi Ctr., Rome ; INFN, Bologna ; Bologna U. ; CERN)
Unexpected features of the BABAR data on e+e−→ BB cross sections (B stands for baryon) are discussed. These data have been collected, with unprecedented accuracy, by means of the initial state radiation technique, which is particularly suitable in giving good acceptance and energy resolution at threshold.

SuperB
: A High-Luminosity Asymmetric $e^+ e^-$ Super Flavour Factory : Conceptual Design Report
/ Bona, M.
The physics objectives of SuperB, an asymmetric electron-positron collider with a luminosity above 10^36/cm^2/s are described, together with the conceptual design of a novel low emittance design that achieves this performance with wallplug power comparable to that of the current B Factories, and an [...]

Measurement of single electron production up to 45 GeV/c transverse momentum at the CERN ISR
/ Pérez, P ; Banner, M ; Clark, A G ; Darriulat, Pierre ; Eggert, K ; Hungerbühler, V ; Jenni, Peter ; Modis, T ; Smadja, G ; Strauss, J S et al.
The production of single electrons of transverse momentum between 1.8 and 4.5 GeV/c is measured in pp collisions at \sqrt{s}=53 and 63 GeV. Contributions from rho , omega , phi , psi , Upsilon , DD and Drell-Yan pairs are deduced from measurements in the same apparatus..

A remotely controlled high voltage power supply system for multiwire and drift chambers
/ Bologna, G ; Celani, F ; Codino, A ; D'Ettorre-Piazzoli, B ; Fabbri, F L ; Levy, G ; Mannocchi, G ; Picchi, P ; Rivellini, G ; Satta, L et al.
The authors describe a remotely controlled power supply multichannel system delivering a current of 200 mu A per channel up to 5.5 kV, and allowing voltage setting as well as current monitoring. The system is presently used in the charmed meson photoproduction experiment (NA1) at SPS, CERN. [...]

Electron-muon coincidences in proton-proton collisions at the CERN Intersecting Storage Rings
/ Clark, A G ; Banner, M ; Darriulat, Pierre ; Eggert, K ; Hungerbühler, V ; Jenni, Peter ; Lapuyade, C ; Modis, T ; Pérez, P ; Renshall, H et al.
In an experiment carried out at the CERN Intersecting Storage Rings with a highly selective electron spectrometer system and a magnetized iron filter to detect muons, the authors have observed 32+or-16 dilepton events of the type p+p to mu /sup +or-/+e/sup -or+/+... The integrated luminosity of the experiment was (2.0+or-0.1)*10/sup 37/ cm /sup -2/, and the over-all detection efficiency 0.14+or-0.07. [...]
