Systematic Study of Low-mass Electron Pair Production in P{be and P{au Collisions at 450 Gev/c
In a joint eeort the CERES/NA45 and TAPS collaborations have measured low-mass electron pairs in p{Be and p{Au collisions at 450 GeV/c at the CERN SPS. In the range covered up to 1.5 GeV/c 2 the mass spectra from p{Be and p{Au collisions are well explained by electron pairs from decays of neutral mesons. For p{Au our result is new. For p{Be, the simultaneously measured electron pairs and photon...
متن کاملLow-Mass Lepton Pair Production in Pb-Au Collisions at 40 AGeV
The CERES/NA45 experiment at the CERN SPS has previously measured ee pair production in 160 AGeV Pb-Au collisions. In the mass region m>0.2 GeV/c, an enhancement of 2.7±0.4(statist.)±0.5(syst.) compared to the expectation from known hadronic decay sources was observed. In the 40 AGeV data taken in 1999, an enhancement is again found; a preliminary analysis gives the even larger value of 4.5 ± 1...
متن کاملLepton Pair Production in Tagged Collisions at the L3 Experiment
We studied lepton pair production in single-tagged events using the L3 detector at LEP. A measurement of the process cross section is given for 1:4 GeV 2 < Q 2 < 7:6 GeV 2 and 60 GeV 2 < Q 2 < 140 GeV 2. The F 2 photon structure function is then extracted at < Q 2 >= 1:7 GeV 2. Finally a study of az-imuthal correlations is used to gain access to some so far unmeasured photon structure functions.
متن کاملNeutral meson production in p - Be and p - Au collisions at 450 GeV beam
In a joint experiment the TAPS and CERES collaborations have studied the production of the neutral mesons ; and ! in 450 GeV p-Be and p-Au collisions at the CERN SPS. The mesons were identiied by their ! , ! , and ! ! decay modes. The cross sections were measured down to very low p T (20 MeV/c) near mid-rapidity (3:0 < y < 4:0). The and ! cross sections are smaller than expected from extrap-ola...
متن کاملLepton-pair production in nuclear collisions - past, present, future
The key results on lepton-pair production in ultra-relativistic nuclear collisions are shortly reviewed, starting at the roots of pp collisions in the seventies, and ending at the perspectives of the colliders RHIC and LHC. The presence is dominated by the recent precision results from NA60 at the CERN SPS, culminating in the first measurement of the in-medium ρ spectral function and the transv...
