Experimental constraints on extra dimensions / Mele, S (CERN)
In the last few years the proposed existence of large extra dimensions has changed the landscape of high energy physics, suggesting longly sought answers to fundamental questions like the hierarchy problem. To date, several theoretical models have been proposed and a vigorous experimental effort has started, aimed to hunt for manifestations of extra dimensions in form of deviations from the Newton law in short-range tests of gravity or as new particle interactions at the world’s most powerful colliders.

Higher Educ.) ; Antinori, F (Padua U. ; INFN, Padua) ; Bacon, P A (Birmingham U.) ; Badalà, A (Catania U. ; INFN, Catania) ; Barbera, R (Catania U. ; INFN, Catania) ; Belogianni, A (Athens U.) ; Bhasin, A (Birmingham U.) ; Bloodworth, I J (Birmingham U.) ; Bombara, M (Kosice, IEF) ; Bruno, G E (Bari U. ; INFN, Bari) et al. /NA57
The NA57 experiment has measured strange baryon and antibaryon production in Pb-Pb collisions at 40 A GeV/c and 160 A GeV/c beam momenta. This presentation covers strangeness enhancement and transverse spectra from the 160 A GeV/c data, and energy dependence of the particle yields. [...]

Particle identification with the ALICE TOF detector at very high particle multiplicity / Akindinov, A (Moscow, ITEP) ; Alici, A (Bologna U. ; INFN, Bologna) ; Anselmo, F (INFN, Bologna) ; Antonioli, P (INFN, Bologna) ; Baek, Y W (CERN ; World Lab, Lausanne) ; Basile, M (Bologna U. ; INFN, Bologna) ; Cara Romeo, G (INFN, Bologna) ; Cerron Zeballos, E (CERN ; World Lab, Lausanne) ; Cifarelli, L (Bologna U. ; INFN, Bologna) ; Cindolo, F (INFN, Bologna) et al. /ALICE TOF
A procedure developed to achieve particle identification in very high multiplicity conditions using a complex time-of-flight system is illustrated in detail by simulating and studying the performance of the ALICE TOF detector in a realistic scenario of Pb-Pb and p-p interactions at LHC..

Production and decay of $\eta^\prime$(958) and $\eta$(1440) in $\bar{p} p$ annihilation at rest / Amsler, Claude (U. Zurich (main)) ; Anisovich, A V (U. Bonn (main)) ; Baker, C A (Rutherford) ; Barnett, B M (U. Bonn (main)) ; Batty, C J (Rutherford) ; Blum, P (Karlsruhe U.) ; Braune, K (LMU Munich (main)) ; Credé, V (U. Bonn (main)) ; Crowe, K M (LBNL, Berkeley) ; Doser, M (CERN) et al.
We report on a study of four reactions in $\bar{\mathrm p}{\mathrm p}$ annihilation at rest, of $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^-\eta$, $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^- 2\pi^0$, $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^-\gamma$ and $\bar{\mathrm p}{\mathrm p}\rightarrow 4\pi^0\eta$. The $\eta^\prime$ and the $\eta$(1440) are seen in their decays into $\pi^ + \pi^-\eta$, $\pi^0\pi^0\eta$ and $\pi^ + \pi^-\gamma$ ; no signal is seen in the $4\pi$ invariant mass distribution. [...]

A measurement of $\Lambda$ polarization in inclusive production by $\Sigma^-$ of 340-GeV/c in C and Cu targets / Adamovich, M I (LPI, Moscow (main)) ; Alexandrov, Yu A (LPI, Moscow (main)) ; Baranov, S P (LPI, Moscow (main)) ; Barberis, D (Genoa U. ; INFN, Genoa) ; Beck, M (Heidelberg, Max Planck Inst.) ; ́erat, C B (Grenoble, CEN) ; Beusch, W (CERN) ; Boss, M (Heidelberg U.) ; Brons, S (Heidelberg, Max Planck Inst.) ; Brückner, W (Heidelberg, Max Planck Inst.) et al. /WA89
We have measured the polarization of $\Lambda$ hyperons produced inclusively by a $\Sigma^-$ beam of 340 GeV/c momentum in nuclear targets. From a sample of 9.5 millions of identified $\Lambda$ decays, polarizations were determined in the range $x_F \gt 0.1$ and $p_t\leq 1.6$ GeV/c . [...]

Search for top and bottom squarks / Rott, Carsten (Purdue U.) /ALEPH ; CDF ; DELPHI ; L3 ; OPAL
Searches for the lightest scalar top quark $\tilde{t}_1$ and scalar bottom quark $\tilde{b}_1$ performed at LEP2 with a center-of-mass energy of up to $\sqrt{s}=209$ GeV and at Tevatron using data collected at $\sqrt{s}=1.8$ TeV during Run I and at $\sqrt{s}=1.96$ TeV during Run II, are discussed. Different possible decay modes were considered and no evidence for any such signal was observed. [...]

Diamond detectors with subnanosecond time resolution for heavy ion spill diagnostics / Moritz, P (Darmstadt, GSI) ; Berdermann, E (Darmstadt, GSI) ; Blasche, K (Darmstadt, GSI) ; Rodl, H (Darmstadt, GSI) ; Stelzer, H (Darmstadt, GSI) ; Zeytouni, F (Frankfurt U.)
The application of CVD diamonds as radiation-hard particle detectors with outstanding properties for heavy ion beamline diagnostics is presented. Synchrotron particle spills ranging from a single ion to well beyond $10^8$  pps can be analyzed while maintaining single-particle time resolution below fractions of a nanosecond. [...]

Diamond detectors for heavy ion measurements / Berdermann, E (Darmstadt, GSI) ; Blasche, K (Darmstadt, GSI) ; Moritz, P (Darmstadt, GSI) ; Stelzer, H (Darmstadt, GSI) ; Zeytouni, F (Frankfurt U.)
En 1999, the accelerator facility at GSI is scheduled to deliver beam intensities of about $10^{10}$ particles spill for all available ions up to $^{238}$U. This necessitates the development of a new generation of radiation-resistent and ultra-fast detectors, in conjunction with new high-speed and low-noise electronics. [...]
