Download Energy Dependence of the Ridge in High Multiplicity Proton-proton Collisions Book in PDF, Epub and Kindle
In this study, we demonstrate that the recent measurement of azimuthally collimated, long-range rapidity ("ridge") correlations in √s=13 TeV proton-proton (p+p) collisions by the ATLAS Collaboration at the LHC are in agreement with expectations from the color glass condensate effective theory of high-energy QCD. The observation that the integrated near-side yield as a function of multiplicity is independent of collision energy is a natural consequence of the fact that multiparticle production is driven by a single semihard saturation scale in the color glass condensate framework. We argue further that the azimuthal structure of these recent ATLAS ridge measurements strongly constrains hydrodynamic interpretations of such correlations in high-multiplicity p+p collisions.

Download Quark-gluon Plasma, Heavy Ion Collisions And Hadrons Book in PDF, Epub and Kindle
This third book on Quark-Gluon plasma and heavy ion collisions follows the previous ones, published in 1988 and 2005, that described theoretical proposals for a large program, and then the QGP discovery at RHIC.The present one describes the rather mature field, with extensive program at RHIC and LHC colliders and corresponding theory. QGP turns out to be a strongly coupled medium made up of quarks and gluons, existing in exploding fireballs. It is the hottest form of matter created in a laboratory. Other subjects discussed in the book are QCD vacuum structure, including topological solitons and nonperturbative phenomena. It also includes some recent progress in theory of hadrons, bridging hadronic spectroscopy with partonic observables.

Download Multiple Parton Interactions at the LHC Book in PDF, Epub and Kindle
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.

Download Strangeness Enhancement in High Multiplicity Proton-proton Collisions at √s Book in PDF, Epub and Kindle
ALICE is one of the seven experiments at the Large Hadron Collider (LHC) at CERN, dedicated to the physics of heavy-ion collisions and, in particular, the properties of the Quark Gluon Plasma (QGP). IN addition to studying Pb-Pb collisions at \(\sqrt{sNN}\) = 2.76 TeV, ALICE has an extensive proton-proton (p-p) programme (\(\sqrt{s}\) = 0.9, 2.76, 7 and 8 TeV) aimed to provide a base for comparison with the Pb-Pb data as well as to complement the research in areas where ALICE is competitive with the other LHC experiments. Of particular interest for the ALICE collaboration are the high-multiplicity p-p events. As suggested by the Bjorken formula for the initial energy density in high energy collisions, such events could create conditions comparable to those in heavy-ion collisions at RHIC where the formation of the QGP has been observed. The identified charged hadron spectra in p-p collisions at \(\sqrt{s}\) = 7 TeV have been measured as a function of the event multiplicity, looking for signs of strangeness enhancement as one of the established signatures for the QGP formation. The analysis entails processing a sample of ~ 80 M minimum-bias and ~ 5 M high-multiplicity triggered p-p events. Three different particle identification techniques have been developed and assessed for the purpose of measuring the pion, kaon and proton yields over a momentum range of 0.2 GeV/c \(\leq\) pT \(\leq\) 2.5 GeV /c. A study of the systematic effects and the results are presented, including pT spectra and integrated yields for pions, kaons and protons, K \( \pm\)/\(\Pi\)\( \pm\) and p\( \pm\)/\(\Pi\)\( \pm\) ratios as a function of multiplicity, and a comparison to recent models. No significant variation in the particle ratios is observed up to multiplicities of the order of dN\(_{ch}\)/d\(\eta\) \(\approx\) 42.
