In autumn 2003 data taking with the new Silicon Vertex Detector SVD2 in Belle started at the KEK-B energy-asymmetric e+ e- collider in Tsukuba, Japan. The detector works as expected, however, it was decided to produce replacement ladders for the inner two layers of the vertex detector which are most exposed to the high radiation doses from the beam. The new ladders are not merely reproducing the existing design but include some significant improvements. The readout electronics is designed in a FR4 hybrid board with a new heat transfer scheme in order to dissipate the heat produced in the VA1TA front-end readout chips. The flex circuits that connect the double-sided silicon sensors (DSSD's) with the hybrid boards were redesigned using a 2-layer technique which improved the production quality and lowered their costs significantly. Production and testing will he finished by the end of 2004 and will provide Belle with spare ladders as well as new expertise for possible future projects like e.g. developments for a high luminosity B-factory. © 2004 IEEE.

We present a newly developed fast trigger system that uses the silicon vertex detector (SVD) for the Belle experiment at the KEKB energy-asymmetric e+e- collider. It is designed to issue the trigger with a latency of 1.85 μs for the Belle central trigger system (GDL). The primary purpose of the SVD trigger is to reduce beam-induced background events by requiring tracks that come from the interaction point. The system receives trigger signals from VA1TA front-end integrated circuits, which read out signals on the silicon-strips. SVD tracks are constructed with them in combination with the trigger information of the Central Drift Chamber (CDC), which is located outside the SVD. Performance of the SVD trigger is evaluated with collision data. © 2004 IEEE.

During the summer shutdown of 2003 the new silicon vertex detector SVD2 was installed in Belle at the KEK-B factory in Tsukuba, Japan and started to take data in October 2003. It provides important improvements in the tracking capabilities and adds new trigger functionality. In addition a new hardware trigger level 1.5 was designed and installed that takes advantage of the digitized SVD hit data. The improvement in the Belle trigger system is important to deal with the increasing luminosity and higher beam currents of the KEK-B collider. The design of the level 1.5 trigger system is reviewed and results from the data taking are presented.

Transverse momentum spectra and yields of hadrons are measured by the PHENIX collaboration in Au+Au collisions at sNN=130GeV at the Relativistic Heavy Ion Collider. The time-of-flight resolution allows identification of pions to transverse momenta of 2GeV∕c and protons and antiprotons to 4GeV∕c. The yield of pions rises approximately linearly with the number of nucleons participating in the collision, while the number of kaons, protons, and antiprotons increases more rapidly. The shape of the momentum distribution changes between peripheral and central collisions. Simultaneous analysis of all the pT spectra indicates radial collective expansion, consistent with predictions of hydrodynamic models. Hydrodynamic analysis of the spectra shows that the expansion velocity increases with collision centrality and collision energy. This expansion boosts the particle momenta, causing the yield from soft processes to exceed that for hard to large transverse momentum, perhaps as large as 3GeV∕c.

Bose-Einstein correlations of identically charged pion pairs were measured by the PHENIX experiment at midrapidity in Au+Au collisions at sNN=200 GeV. The Bertsch-Pratt radius parameters were determined as a function of the transverse momentum of the pair and as a function of the centrality of the collision. Using the standard core-halo partial Coulomb fits, and a new parametrization which constrains the Coulomb fraction as determined from the unlike-sign pion correlation, the ratio Rout/Rside is within 0.8–1.1 for 0.25<〈kT〉<1.2 GeV/c. The centrality dependence of all radii is well described by a linear scaling in Npart1/3, and Rout/Rside for 〈kT〉∼0.45 GeV/c is approximately constant at unity as a function of centrality.

J/ψ production has been measured in proton-proton collisions at s=200 GeV over a wide rapidity and transverse momentum range by the PHENIX experiment at the Relativistic Heavy Ion Collider. Distributions of the rapidity and transverse momentum, along with measurements of the mean transverse momentum and total production cross section are presented and compared to available theoretical calculations. The total J/ψ cross section is 4.0±0.6(stat)±0.6(syst)±0.4(abs) μb. The mean transverse momentum is 1.80±0.23(stat)±0.16(syst) GeV/c.

Event-by-event fluctuations of the average transverse momentum of produced particles near midrapidity have been measured by the PHENIX Collaboration in sNN=200 GeV Au+Au, and p+p collisions at the Relativistic Heavy Ion Collider. The fluctuations are observed to be in excess of the expectation for statistically independent particle emission for all centralities. The excess fluctuations exhibit a dependence on both the centrality of the collision and on the pT range over which the average is calculated. Both the centrality and pT dependence can be well reproduced by a simulation of random particle production with the addition of contributions from hard-scattering processes.

We present a measurement of the double longitudinal spin asymmetry in inclusive π0 production in polarized proton-proton collisions at s=200 GeV. The data were taken at the Relativistic Heavy Ion Collider with average beam polarizations of 0.27. The measurements are the first in a program to study the longitudinal spin structure of the proton, using strongly interacting probes, at collider energies. The asymmetry is presented for transverse momenta 1–5 GeV/c at midrapidity, where next-to-leading-order perturbative quantum chromodynamic (NLO pQCD) calculations well describe the unpolarized cross section. The observed asymmetry is small and is compared to a NLO pQCD calculation with a range of polarized gluon distributions.

First results on charm quarkonia production in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) are presented. The yield of J∕ψ’s measured in the PHENIX experiment via electron-positron decay pairs at midrapidity for Au-Au reactions at sNN=200GeV is analyzed as a function of collision centrality. For this analysis we have studied 49.3×106 minimum bias Au-Au reactions. We present the J∕ψ invariant yield dN∕dy for peripheral and midcentral reactions. For the most central collisions where we observe no signal above background, we quote 90% confidence level upper limits. We compare these results with our J∕ψ measurement from proton-proton reactions at the same energy. We find that our measurements are not consistent with models that predict strong enhancement relative to binary collision scaling.
