Available in PDF, EPUB and Kindle. Book excerpt: The highest net baryon density possible in the laboratory--up to ten times normal nuclear density--is expected in the central region of collisions of heavy nuclei (A ≈ 200) at energies near 10 GeV per nucleon. The transverse energy (E{sub T}) distribution, as well as yields of identified particles (?, K+ and protons), from 197Au + 197Au at 11.64A GeV/c are presented. Two key observations are a large degree of proton s̀̀topping, ̀̀indicating multiple scatterings of the incident nucleons, and a proportional relationship of the pion production to the number of participating nucleons. Strangeness enhancement, a proposed signature of the quark-gluon plasma, is studied via the K+/?+ ratio, which achieves the value of 21% without a strong centrality dependence. Comparisons to similar data taken with a 14.6A GeV/c beam of 28Si are made.

Book Synopsis Identified Particle Transverse Momentum Distributions from AU + AU Collisions at 62.4 GeV Per Nucleon Pair by : Conor Henderson
Download or read book Identified Particle Transverse Momentum Distributions from AU + AU Collisions at 62.4 GeV Per Nucleon Pair written by Conor Henderson and published by . This book was released on 2005 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transverse momentum (PT) distributions for pions, kaons, protons and antiprotons have been measured near mid-rapidity for Au+Au collisions at sNN = 62.4 GeV using the PHOBOS detector at the Relativistic Heavy-Ion Collider (RHIC) in Brookhaven National Laboratory. Particle identification is performed using the PHOBOS Time-of-Flight plastic scintillator walls and specific energy loss in the multi-layer silicon Spectrometer, which is also used for track reconstruction and momentum-determination. The spectra are corrected for all detector-dependent effects, including feed-down from weak decays. At PT 3 GeV/c, protons are measured to be the dominant species of charged hadrons and scale much faster with respect to collision centrality than mesons. This behaviour at 62.4 GeV is found to be remarkably similar to that observed in Au+Au collisions at 200 GeV, an interesting observation which should serve as an important constraint on the various mechanisms which have been proposed to describe particle production over this PT range. Baryon stopping, the transport of baryon number from intial beam rapidity, is explored through the net proton (p - p) yields at mid-rapidity. These results fill a large gap between the SPS and higher RHIC energies and as such form an important set of data for comparing to models of baryon transport mechanisms.

Book excerpt: In the last few years, studies of heavy-ion collisions at high energy have produced new insight into the production of nuclear matter at high baryon density and temperature. While heavy-ion reactions at AGS energy are now well characterized, to clarify and test our understanding of the reaction mechanism of these collisions it is important to study the underlying processes involved. The study of p-A collisions should be particularly useful to understand in which way A-A collisions differ from the simple superposition of nucleon-nucleon collisions and it may be a specially severe test of the validity of the models in describing the transition from a single collision problem to a thermodynamic problem mainly defined by a few observables. In particular, p-A collisions should be sensitive to the way nucleons propagate in the nuclear medium and thus provide more insight on: the importance of rescattering, the stopping power of normal nuclear matter, and possibly on the influence of the nuclear matter density and temperature on the hadronic cross sections. In this paper we present the transverse energy and charged particle multiplicity distributions in proton induced collisions on Al, and Pb targets at 14.6GeV/c. These data have been obtained as part of the E814 collaboration and are thus immediately comparable to similar data obtained for 28Si and Au induced reactions at the same energy.

Book excerpt: In this article, we present recent results on particle production from Au+Au collisions at 11 A GeV/c obtained by the E866 experiment. The experiment studies the particle production in high baryon density matter created in central Au + Au collisions. Preliminary results of proton and pion production have been reported in previous Quark Matter conferences. Two particle correlation data for Au + Au collisions in this experiment are presented in another paper in this conference.

Book excerpt: An analysis of the proton rapidity distribution in central 16 O + Au collisions at 60 GeV/n measured in the NA35 streamer chamber detector at the CERN SPS is presented. The charge excess of positive particles over negative particles was measured. The rapidity distribution of the charge excess which can be associated with the primordial protons in the collision is studies in terms of the nuclear stopping power and is compared to the predictions of various models. 7 refs., 2 figs.

This book was released on 2003 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) In the mid-rapidity region, the yield of charged particles evolves smoothly as a function of [the square root of] sNN and collision centrality.

Book Synopsis Multiple Parton Interactions at the LHC by : Paolo Bartalini
Download or read book Multiple Parton Interactions at the LHC written by Paolo Bartalini and published by World Scientific Publishing. This book was released on 2018-11-08 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many high-energy collider experiments (including the current Large Hadron Collider at CERN) involve the collision of hadrons. Hadrons are composite particles consisting of partons (quarks and gluons), and this means that in any hadron–hadron collision there will typically be multiple collisions of the constituents — i.e. multiple parton interactions (MPI). Understanding the nature of the MPI is important in terms of searching for new physics in the products of the scatters, and also in its own right to gain a greater understanding of hadron structure. This book aims at providing a pedagogical introduction and a comprehensive review of different research lines linked by an involvement of MPI phenomena. It is written by pioneers as well as young leading scientists, and reviews both experimental findings and theoretical developments, discussing also the remaining open issues.

Book Synopsis Backward Emission of Protons in Au+Au Collisions at 11.7 A. GeV/c by :
Download or read book Backward Emission of Protons in Au+Au Collisions at 11.7 A. GeV/c written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present preliminary results for the emission of target rapidity protons in minimum bias and central 11.7 A. GeV/c Au+Au collisions. The data span the pseudo-rapidity range [vert-bar][eta][vert-bar] [le] 0.76 and proton kinetic energy range of 50 [le] E [le] 200 MeV. The slopes of the kinetic energy spectra and dN/d[eta] values for central and minimum bias collisions are strikingly similar. Comparison of the results to results for Si+Au and p+A shows that the shape of the dN/d[eta] distribution is independent of the reaction system or centrality suggesting that the spectator matter does not play a decisive role in determining the shape of the proton distributions at back angles for these systems at AGS energies.
