A measurement of direct photon production in ${}^{208}\mathrm{Pb}{+}^{208}\mathrm{Pb}$ collisions at $158A$ GeV has been carried out the CERN WA98 experiment. The invariant yield photons central is extracted as a function transverse momentum interval $0.5<{p}_{T}<4\mathrm{GeV}/c$. significant signal, compared to statistical and systematical errors, seen ${p}_{T}>1.5\mathrm{GeV}/c$. result constitutes first observation ultrarelativistic heavy-ion collisions. It could be for diagnosis...
A comprehensive review of the present understanding, both theoretical and experimental, intrinsic rotational level structures in medium-heavy deformed odd-odd nuclei is presented. discussion various experimental methods presented, emphasizing need for a variety approaches. The that are immediately amenable to fruitful additional study pointed out. structures, Gallagher-Moszkowski (GM) splittings, Newby (N) shifts, role residual $p\ensuremath{-}n$ interaction Currently available data...
Two-particle correlations of direct photons were measured in central 208Pb+208Pb collisions at 158A GeV. The invariant interferometric radii extracted for 100<K(T)<300 MeV/c and compared to from charged pion correlations. yield soft photons, K(T)<300 MeV/c, was the correlation strength theoretical calculations.
Event-by-event fluctuations in the multiplicities of charged particles and photons, total transverse energy 158AGeV Pb+Pb collisions are studied for a wide range centralities. For narrow centrality bins multiplicity distributions found to be near perfect Gaussians. The effect detector acceptance on has been demonstrated follow statistical considerations. dependence particle measured data agree reasonably well with those obtained from participant model. However, photons have lower compared...
The production of neutral pions in 158AGeV Pb+Pb collisions has been studied the WA98 experiment at CERN SPS. Transverse momentum spectra are for range 0.3 GeV/c < mT-m0 4.0 GeV/c. results central compared to various models. centrality dependence pion spectral shape and yield is investigated. An invariance a simple scaling with number participating nucleons observed centralities greater than about 30 which most naturally explained by assuming an equilibrated system.
Several hadronic observables have been studied in central $158A \mathrm{GeV}$ Pb+Pb collisions using data measured by the WA98 experiment at CERN: single ${\ensuremath{\pi}}^{\ensuremath{-}}$ and ${K}^{\ensuremath{-}}$ production, as well two- three-pion interferometry. The Wiedemann-Heinz hydrodynamical model has fitted to pion spectrum, giving an estimate of temperature transverse flow velocity. Bose-Einstein correlations between two identified analyzed a function ${k}_{T},$ different...
Neutral pion transverse momentum spectra were measured in p+C and p+Pb collisions at sqrt[S{NN}]=17.4 GeV midrapidity (2.3 less than or approximately equal eta{lab} 3.0) over the range 0.7 p{T} 3.5 GeV/c. The are compared to pi{0} Pb+Pb sqrt[S{NN}]=17.3 same experiment. For a wide of centralities (N{part} 300), yield pi{0}'s with greater 2 GeV/c is larger consistent yields scaled number nucleon-nucleon (N{coll}), while for central N{part}greater 350, suppressed.
We report on the studies of Transverse-Momentum-Dependent distributions (TMDs) at a future fixed-target experiment –AFTER@LHC– using [Formula: see text] or Pb ion LHC beams, which would be most energetic ever performed. AFTER@LHC opens new domains particle and nuclear physics by complementing collider-mode experiments, in particular those RHIC EIC projects. Both with an extracted beam bent crystal internal gas target, luminosity achieved surpasses that up to 3 orders magnitude. With...

The versus neutral correlations common η−φ phase space regions varying azimuthal size analyzed by two different methods. analysis provides a model-independent demonstration nonstatistical both particle photon multiplicities limited regions. However, no correlated charge-neutral observed, contrary to expectations for production disoriented chiral condensate....
Three-particle correlations have been measured for identified pi(-) from central 158A GeV Pb+Pb collisions by the WA98 experiment at CERN. A substantial contribution of genuine three-body correlation has found as expected a mainly chaotic and symmetric source.
