Available in PDF, EPUB and Kindle. Book excerpt: The nuclear fluid dynamical model with final thermal breakup is used to study the reactions 2°Ne + 238U and 4° Ar + 4°Ca at E{sub LAB}=390 MeV/n. Calculated double differential cross sections d2?/d?dE are in agreement with recent experimental data. It is shown that azimuthally dependent triple differential cross sections d3?/dEd cos?d? yield considerably deeper insight into the collision process and allow for snapshots of the reactions. Strongly correlated jets of nuclear matter are predicted.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Mesons composed of heavy quark-antiquark pairs, known as quarkonia, provide the only direct probe of the screening length in the deconfined state of quarks and gluons, known as the quark gluon plasma (QGP), which is believed to be produced in high energy heavy ion collisions. However, the observation of suppression of quarkonia production in heavy ion collisions at high energies is complicated by the modification of quarkonia production in normal nuclear matter. Measuring the modification of quarkonia production due to the effects of normal nuclear matter, often termed cold nuclear matter (CNM) effects, provide a critical baseline for understanding the properties of the QGP. Measurements of CNM effects on quarkonia production are also interesting in their own right, and can be measured independently in proton-nucleus (p+A) collisions. The modification of quarkonia production in p+A collisions provides insight into quarkonia production mechanisms unavailable through the study of proton-proton collisions alone. The study of quarkonia production in p+A collisions over a wide range of kinematic variables can also provide constraints on the modification of parton distribution functions in nuclei. In order to quantify the CNM effects present at the Relativistic Heavy Ion Collider (RHIC), the PHENIX experiment has recorded data on d+Au collisions at \sqsn=200 GeV. The analysis of J/psi→e+e- and psi'→e+e- production from that data set is presented here. Both J/psi and psi' production are found to be suppressed in d+Au relative to p+p collisions, with the suppression increasing for collisions with small impact parameters. The psi' production is found to be much more suppressed than J/psi production, a result which is unexpected based on measurements at lower collision energy and present theoretical pictures. A parametrization of the J/psi modification measured by PHENIX in terms of two CNM effects is also presented. One is the nuclear breakup of the forming quarkonium state through collisions with nucleons during the d+Au collision. The other is the modification of the gluon distribution in the Au nucleus. It is found that the two effects can be separated due to the very different impact parameter dependencies. A strongly non-linear geometric dependence on the modification of the gluon distribution function is observed, with the modification found to be concentrated near the center of the Au nucleus. This parametrization is also used to estimate the modification of J/psi production in Au+Au collisions due to CNM effects. This modification is compared to PHENIX measurements of J/psi production in Au+Au collisions. Suppression of J/psi production in Au+Au collisions beyond CNM effects is observed. This excess suppression is interpreted as suppression of J/psi production due to the formation of a QGP.

Available in PDF, EPUB and Kindle. Book excerpt: The emulsion technique is being used to examine the angular and momentum distribution of fragments emitted from nonperipheral collisions between emulsion nuclei (AgBr) and heavy-ion projectiles 4He, 16O, and 4°Ar in the range of energies 0.2 to 2.1 GeV/A. Selection criteria, scanning and measuring, measurements, and analytic procedure are addressed. Prong number distributions, range and angular distributions are shown. The following conclusions were drawn: there is no unique particle-emitting system; prong distributions dN/dtheta are broad and Maxwellian-like, with maxima that shift toward smaller angles as the fragment energy increases, and as the beam energy decreases; no statistically significant structure attributed to well-defined collective phenomena is observed; there is no evidence that the angular distribution for low-energy fragments depends on the impact parameters of the collision between heavy ions at 2.1 GeV/A; at 2.1 GeV/A the number of fragments per event emitted in the backward hemisphere is insensitive to projectile mass. 6 figures, 3 tables.

Available in PDF, EPUB and Kindle. Book excerpt: One of the main goals of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) is to produce very hot, dense nuclear matter by colliding two heavy ions at relativistic energy. The matter produced under these extreme conditions is supposed to be in a de-confined phase, commonly known as Quark Gluon Plasma (QGP), which is believed to have existed for a very short time after the Big Bang. RHIC is devoted to the study of the QGP phase. One of the probes that carry information of this hot matter is the elliptic flow (azimuthal asymmetry in particle production). The elliptic flow occurs due to the spatial asymmetry of the overlap region of the two colliding nuclei at non-zero impact parameter. Particle production is azimuthally asymmetric due to asymmetry in the pressure gradient. The matter formed in central collisions of Au+Au at 200 GeV at RHIC seems to behave like a perfect fluid. This conclusion is based in part on approximate agreement between non-viscous hydrodynamic calculations and the experimental data on elliptic flow. The hydrodynamic calculations predict the saturation of the strength of the elliptic flow, v2, with increase in transverse particle density, (1/S)(dNch/dy), at fixed impact parameter. The transverse particle density in central Au+Au is not enough to confirm this. Uranium + uranium (U+U) collisions have the potential to produce more extreme conditions of excited matter then is possible using spherical nuclei like gold or lead at the same incident energy. Uranium has quadrupole deformed shape. The collisions of special interest are the "ideal tip-tip" orientation in which the long axes of both deformed nuclei are aligned with the beam axis at zero impact parameter, and the "ideal body-body" orientation in which the long axes are both perpendicular to the beam axis and parallel to each other at zero impact parameter. The "ideal tip-tip" and "ideal body-body" collision events allow to test the hydro prediction by varying the transverse particle density at spatial eccentricity similar to central Au+Au, and spatial eccentricity at transverse particle density similar to central Au+Au, respectively. However, this potential of U+U collisions will be lost unless these desired collision events are selected. Configurations close to the "ideal tip-tip" and "ideal body-body" are referred as "tip-tip" and "body-body" for selection purposes, as the probability of ideal cases is negligible. I have studied U+U collisions at 200 GeV using different model simulations: Monte-Carlo Glauber, Ultra-relativistic Quantum Molecular Dynamics (UrQMD) and A Multi-Phase Transport Model (AMPT). I have compared the advantages from U+U collisions at 200 GeV including the effect due to the STAR detector's resolution, and also shown a way to separate the desired collision configurations based on experimental observables. U+U collisions are planned at RHIC when the new ion source (the EBIS ion source) will be operational, around 2010.

Book excerpt: Doctoral Thesis / Dissertation from the year 2007 in the subject Physics - Nuclear Physics, grade: 1,0, University of Frankfurt (Main) (Institut für Kernphysik), language: English, abstract: Quarks sind die elementaren Bestandteile, aus denen Hadronen (Baryonen und Mesonen) aufgebaut sind. Zusammen mit den Leptonen und den Eichbosonen gelten sie heute als die fundamentalen Bausteine, aus denen alle Materie aufgebaut ist. Im Standardmodell der Teilchenphysik werden diese Ergebnisse zusammengefasst. Es gibt sechs verschiedene Quark-Arten (flavours): up, down, strange, charm, bottom und top. In der Natur kommen keine isolierten Quarks vor, sondern nur Kombinationen aus z.B. einem Quark-Antiquark Paar (Meson) oder aus drei Quarks (Baryon). Die Quantenchromodynamik (QCD) beschreibt die starke Wechselwirkung zwischen Quarks und Gluonen. Quarks bauen unter anderem Protonen und Neutronen auf. Gluonen vermitteln die Wechselwirkung zwischen den Quarks. Konzeptionell ist die QCD an die Quantenelektrodynamik (QED) angelehnt, die die Wechselwirkung elektrisch geladener Teilchen (z.B. Elektron oder Positron) durch den Austausch von Photonen beschreibt. Analog wirkt die Kraft, die durch den Austausch von Gluonen beschrieben wird, zwischen Teilchen, die eine Farbladung (rot, grün, blau) tragen. Im Vergleich zur QED, wo das Photon neutral ist, trägt das Gluon selbst Farbe und wechselwirkt daher mit anderen Gluonen. Bei kleinen Quarkabständen und hohen Energien bzw. hohen Impulsüberträgen, fällt die Kopplungskonstante der starken Wechselwirkung (αs) ab. Bei kleinem αs sind Quarks und Gluonen schwach gebunden (Asymptotische Freiheit). Bei grossen Abständen bzw. kleinen Impulsüberträgen ist αs gross. Die Zunahme von αs bewirkt, dass unendlich viel Energie benötigt wird, um Quarks aus Hadronen herauszulösen. Dies hat die Folge, dass es günstiger ist ein neues Quark-Antiquark Paar zu erzeugen. Das erklärt, warum Quarks immer in Hadronen (Mesonen und Baryonen) gebunden sind und nie isoliert beobachtet werden können (Confinement).Wenn Kernmaterie stark komprimiert wird, steigen Energiedichte und Temperatur, und möglicherweise erfährt die Kernmaterie einen Phasenübergang zu einem Zustand der als Quark Gluon Plasma (QGP) bezeichnet wird. Das QGP ist ein Zustand der Materie, in dem das Confinement der Quarks und Gluonen aufgehoben ist (Deconfinement). Dieser Zustand ist gekennzeichnet durch ein quasi-freies Verhalten der Quarks und Gluonen. Quarks und Gluonen in Hadronen ein. Im heutigen Universum existiert das QGP höchstens noch im Zentrum von Neutronensternen und explodierenden schwarzen Löchern.

Book excerpt: This is the sequel to the first volume to treat in one effective field theory framework the physics of strongly interacting matter under extreme conditions. This is vital for understanding the high temperature phenomena taking place in relativistic heavy ion collisions and in the early Universe, as well as the high-density matter predicted to be present in compact stars. The underlying thesis is that what governs hadronic properties in a heat bath and/or a dense medium is hidden local symmetry which emerges from chiral dynamics of light quark systems and from the duality between QCD in 4D and bulk gravity in 5D as in AdS/QCD. Special attention is paid to hot matter relevant for relativistic heavy ion processes and to dense matter relevant for compact stars that are either stable or on the verge of collapse into black holes.
