This writeup is a compilation of the predictions for forthcoming Heavy Ion Program at Large Hadron Collider, as presented CERN Theory Institute 'Heavy Collisions LHC - Last Call Predictions', held from May 14th to June 10th 2007.
The goal of the DIRAC experiment at CERN (PS212) is to measure $\pi^+\pi^-$ atom lifetime with 10% precision. Such a measurement would yield precision 5% on value $S$-wave $\pi\pi$ scattering lengths combination $|a_0-a_2|$. Based part collected data we present first result lifetime, $\tau=[2.91 ^{+0.49}_{-0.62}]\times 10^{-15}$ s, and discuss major systematic errors. This corresponds $|a_0-a_2|=0.264 ^{+0.033}_{-0.020} m_{\pi}^{-1}$.
We have developed a fast Monte Carlo procedure of hadron generation allowing one to study and analyze various observables for stable hadrons resonances produced in ultra-relativistic heavy ion collisions. Particle multiplicities are determined based on the concept chemical freeze-out. Particles can be generated or thermal freeze-out hypersurface represented by parameterization numerical solution relativistic hydrodynamics with given initial conditions equation state. Besides standard...
The fast Monte Carlo procedure of hadron generation developed in our previous work is extended to describe noncentral collisions nuclei. We consider different possibilities introduce appropriate asymmetry the freeze-out hypersurface and flow velocity profile. For comparison with other models experimental data, we demonstrate results based on standard parametrizations profile assuming either a common chemical thermal or chemically frozen evolution from freeze-out. ++ generator code written...
The DIRAC experiment at CERN has achieved a sizeable production of $\pi^+\pi^-$ atoms and significantly improved the precision on its lifetime determination. From sample 21227 atomic pairs, 4% measurement S-wave $\pi\pi$ scattering length difference $|a_0-a_2| = (.0.2533^{+0.0080}_{-0.0078}|_\mathrm{stat}.{}^{+0.0078}_{-0.0073}|_\mathrm{syst})M_{\pi^+}^{-1}$ been attained, providing an important test Chiral Perturbation Theory.
Initial eccentricity and fluctuations of the interaction volume created in relativistic collisions deformed $^{197}\mathrm{Au}$ $^{238}\mathrm{U}$ nuclei are studied using optical Monte Carlo (MC) Glauber simulations. It is found that nonsphericity noticeably influences average central collisions, enhanced from deformation. Quantitative results obtained for $\mathrm{Au}+\mathrm{Au}$ $\mathrm{U}+\mathrm{U}$ at energy $\sqrt{{s}_{\mathit{NN}}}=200$ GeV.
The project NICA (Nuclotron-based Ion Collider fAcility) is aimed to study hot and baryon rich QCD matter in heavy ion collisions the energy range up sNN=11GeV. program includes a of collective phenomena, dilepton, hyperon hypernuclei production under extreme conditions highest baryonic density. This will be performed at fixed target experiment [email protected] with MPD detector collider.
We propose the use of ratios pion-proton correlation functions evaluated under different conditions to study relative space-time asymmetries in pion and proton emission (pion nucleon source shifts) high energy heavy ion collisions. address question noncentral collisions, where sources can be shifted spatially each other both longitudinal transverse directions reaction plane. RQMD event generator illustrate effect technique.
The results of a search for hydrogen-like atoms consisting $\pi^{\mp}K^{\pm}$ mesons are presented. Evidence $\pi K$ atom production by 24 GeV/c protons from CERN PS interacting with nickel target has been seen in terms characteristic pairs their breakup the same ($178 \pm 49$) and Coulomb final state interaction ($653 42$). Using these analysis yields first value lifetime $\tau=(2.5_{-1.8}^{+3.0})$ fs model-independent measurement S-wave isospin-odd scattering length...
The NICA (Nuclotron-based Ion Collider fAcility) project is now under active realization at the Joint Institute for Nuclear Research (JINR, Dubna). main goal of a study hot and dense strongly interacting matter in heavy ion (up to Au) collisions centre-of-mass energies up 11 GeV per nucleon. Two modes operation are foreseen, collider mode extracted beams, with two detectors: MPD [email protected] both experiments preparation stage.
