Mainly\, there is unexpected doubling of the spectrum when comparing to the spectrum ex pected or known from the experiments as well as the ones known from the so lution of the Schroedinger equation. These additional states do not belo ng to the known ghost and non-physical solutions as they have the same sym metry as the usual ones\, however we argue they appear due to the sensitiv ity of BSE to the details of the analytical form of the constituents quark propagators\, more specifically they are consequence of using non-confi ning form of the propagators. To show this explicitly we develop and de scribe the efficient method of the numerical solution of Q-Q BSE and numer ically solve it for the case of pseudo-scalar $c-\\bar{c}$ mesons. For th e bare propagators of constituents we are able to find BSE solution for ar bitrarily high excited state without any 3-dimensional reduction. Unlike to the Schroedinger equation the excited states are not orthogonal. Using free charm quark propagators we observe that the spin $0\,1$ ground states are the only mesons left bellow naive quark threshold $2m_c$\, while the all excited states are situated above this threshold. In the second part of the paper we consider the model of BSE with complex conjugated poles an d show the influence on the spectrum directly in the 3+1 dimensional space .\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=52&confId=1531 91 LOCATION:Peniche\, Portugal URL:http://indico.cern.ch/contributionDisplay.py?contribId=52&confId=15319 1 END:VEVENT BEGIN:VEVENT SUMMARY:Gluon mass through massless bound states excitations.

The main assumption underlying this mechanism \nis that the interaction vertices of the theor y contain masslesss poles\, originating from the dynamical formation of \ nmassless bound-state excitations. In this work we demonstrate that this k ey assumption is indeed realized \nby the QCD dynamics. Specifically\, the corresponding Bethe-Salpeter equation describing the aforementioned massl ess excitations is solved under certain approximations\, \nand non-trivial solutions are obtained.\n\nhttp://indico.cern.ch/contributionDisplay.py?c ontribId=24&confId=153191 LOCATION:Peniche\, Portugal URL:http://indico.cern.ch/contributionDisplay.py?contribId=24&confId=15319 1 END:VEVENT BEGIN:VEVENT SUMMARY:NLO corrections for large multiplicity processes DTSTART;VALUE=DATE-TIME:20120507T173000Z DTEND;VALUE=DATE-TIME:20120507T180000Z DTSTAMP;VALUE=DATE-TIME:20130523T060645Z UID:indico-contribution-153191-27@cern.ch DESCRIPTION:Speakers: MAITRE\, Daniel (CERN)\nRecent progress in the calcu lation of Next-To-Leading order observables in perturbative QCD are presen ted\, with a focus on results from so-called unitarity techniques for high multiplicity processes.\n\nhttp://indico.cern.ch/contributionDisplay.py?c ontribId=27&confId=153191 LOCATION:Peniche\, Portugal URL:http://indico.cern.ch/contributionDisplay.py?contribId=27&confId=15319 1 END:VEVENT BEGIN:VEVENT SUMMARY:The phase diagram in T-mu-Nc space DTSTART;VALUE=DATE-TIME:20120509T083000Z DTEND;VALUE=DATE-TIME:20120509T090000Z DTSTAMP;VALUE=DATE-TIME:20130523T060645Z UID:indico-contribution-153191-20@cern.ch DESCRIPTION:Speakers: LOTTINI\, Stefano (Goethe Universitaet\, Frankfurt a m Main)\nWe examine the phase diagram of hadronic matter when the number o f colours Nc\, as well as temperature and density\, are varied.

High ene rgy collision experiments are particularly sensitive to the correlators of these multiple sources by means of the multiple scattering undergone by t he produced particles. By carefully studying the color structure of severa l multi-particle production processes in the presence of strong color fiel ds\, we show that higher point correlations are suppressed by powers of th e number of colors Nc and\, in particular\, can be neglected in the large- Nc limit.

Using different scenarios for the interaction between projectile and matter\, and different transport prope rties of the matter\, we study the formation and structure of Mach cones. Especially\, a dependence of the Mach cone angle on the details and rate o f the energy deposition from projectile to the matter is investigated. Fur thermore\, the two-particle correlations extracted from the numerical calc ulations are compared to an analytical approximation. We find that the pro pagation of a high energetic particle through the matter does not lead to the appearance of a double peak structure as observed in the ultrarelativi stic heavy-ion collision experiments. The reason is the strongly forward-p eaked energy and momentum deposition in the head shock region. In addition \, by adjusting the cross section we investigate the influence of the visc osity to the structure of Mach cones. A clear and unavoidable smearing of the profile depending on a finite ratio of shear viscosity to entropy dens ity is clearly visible.\n\nhttp://indico.cern.ch/contributionDisplay.py?co ntribId=0&confId=153191 LOCATION:Peniche\, Portugal URL:http://indico.cern.ch/contributionDisplay.py?contribId=0&confId=153191 END:VEVENT BEGIN:VEVENT SUMMARY:Effects of the low lying Dirac modes on excited hadrons in lattice QCD DTSTART;VALUE=DATE-TIME:20120507T103000Z DTEND;VALUE=DATE-TIME:20120507T110000Z DTSTAMP;VALUE=DATE-TIME:20130523T060645Z UID:indico-contribution-153191-3@cern.ch DESCRIPTION:Speakers: Mr. SCHROECK\, Mario (Universitaet Graz)\nChiral sym metry breaking in Quantum Chromodynamics is associated with the low lying spectral modes of the Dirac operator according to the Banks-Casher relatio n.

The reasons why newly detected mesonic enhancements often seem to be incompatible with $q \\bar{q}$ states can be manifold:\n\n (i) the underlying confining potent ial may be different from\n what is generally taken for granted\;\n ( ii) mass shifts due to unitarisation (or "unquenching") are\n mostly neglected\;\n(iii) unitarisation sometimes even yields extra\, dynamically \n generated resonances\, which nevertheless have a $q\\bar{q}$\n source\;\n (iv) the opening of strong decay thresholds generally distort s\n the line shapes of nearby resonances\, or can even by\n them selves give rise to enhancements that look like\n resonances\;\n (v) large inelasticity effects between observed OZI-forbidden\n decays a nd non-observed OZI-allowed ones can lead to\n signal depletion at tr ue resonances and/or thresholds\,\n resulting in non-resonant apparen t enhancements in between.\n\nIn this talk\, an assessment will be made of the status of meson spectroscopy in the light of the above mechanisms\, w ith several concrete examples of light and heavy-light mesons as well as c harmonium and bottomonium states.

This is the basis of expecting large event-by-event fluctuations for heavy-ion collisions that reach in the critical region. Heavy-ion collisions are however very small and dynamic systems\, which at most reach local thermal equilibrium. The effect of critical slowing down is further expected to limit the size of t he fluctuations.\nWe present a fully dynamic nonequilibrium model of the e volution of the fluctuations of the order parameter of chiral symmetry\, t he sigma field. It is propagated by a Langevin equation and couples to an expanding fluid of quarks and antiquarks. The entire system evolves under energy- and momentum conservation.\nNonequilibrium effects\, like supercoo ling and reheating\, are observed.\nAt a critical point the dynamic correl ation length grows. As a consequence we find an enhancement of event-by-ev ent fluctuations for a scenario with a critical point compared to a first order phase transition.\n\nhttp://indico.cern.ch/contributionDisplay.py?co ntribId=32&confId=153191 LOCATION:Peniche\, Portugal URL:http://indico.cern.ch/contributionDisplay.py?contribId=32&confId=15319 1 END:VEVENT BEGIN:VEVENT SUMMARY:Review of STAR Heavy Ion results DTSTART;VALUE=DATE-TIME:20120510T083000Z DTEND;VALUE=DATE-TIME:20120510T090000Z DTSTAMP;VALUE=DATE-TIME:20130523T060645Z UID:indico-contribution-153191-11@cern.ch DESCRIPTION:Speakers: KABANA\, Sonia ()\nWe present some highlights of rec ent results from STAR experiment at RHIC.

Nevertheless\, many authors still consider the X(3872) a meson-meson molecule\, due to its very close proximity to the $D ^0D^{*0}$ threshold. It is argued [2] that\, because of this closeness\, t he X(3872) will have a molecular-type wave function\, with a strongly domi nant $D^0D^{*0}$ component\, irrespective of the mechanism creating the st ate. \n\nIn this talk\, I shall present results from a simplified study of this issue\, employing a two-channel model\, i.e.\, one channel for the c onfined axial-vector $c\\bar{c}$ state and another for the dominant S-wave $D^0D^{*0}$ decay component. Harmonic-oscillator wave functions will be u sed for the confinement part and a delta-shell potential for transitions b etween the $c\\bar{c}$ and $D^0D^{*0}$ channels\, thus mimicking string b reaking that gives rise to $^3P_0$ quark-pair creation. Probabilities of t he two wave-function components will be computed as in Ref.

If we consider u and d quarks as degenerate and work i n a theoretical framework that also includes strange states\, then we can construct two isoscalar \\bar q - q states.

By means of \nrelativistic heavy-ion collisions\, these properties are intended \nto be experimentally revealed\, providing also information about \nthe structure of the produced hot matter. One of the r emarkable \nfindings is that the QGP created in experiments at RHIC and LH C \nis an almost ideal fluid obeying\, apart from ultra-cold fermionic \ns ystems near unitarity\, the smallest shear viscosity to entropy \ndensity ratio observed in nature. \n\nBy means of a quasi-particle model for QCD t hermodynamics\, which \nis related to QCD via the two-loop phi-functional formalism\, \nfeaturing dynamically generated self-energies of the excitat ion \nmodes and being extended to non-equilibrium systems \nself-consisten tly within an effective kinetic theory approach\, \nthe temperature depend ence of shear and bulk viscosity \ncoefficients of the QGP is investigated [1]. Showing the \nparametric dependencies on coupling and temperature kn own from \nperturbative QCD at large temperatures\, their extrapolation in to \nthe non-perturbative regime near the deconfinement transition \ntempe rature exhibits fairly nice agreement with available lattice \nQCD results for the pure gluon plasma. Moreover\, the ratio of bulk \nto shear viscos ity depicts at large temperatures the quadratic \ndependence on the confor mality measure known from perturbative \nQCD\, while in the vicinity of th e deconfinement transition a \nlinear behaviour as known from specific str ongly coupled theories \nbased on the gauge/string duality is found [2]. V ia weak coupling \narguments\, an interrelation between the specific shear viscosity \nand the energy loss parameter can be derived [3].

In particular i will concentrate on i) the u nquenching of the gluon propagator through the SDEs as well as ii) the com parison of these results with new lattice data obtained from configuration s containing 2 light and two heavy quarks\, iii) the all order equation th at describes the dynamically generated gluon mass\, and finally iv) a new method that allows for lattice simulations in background field gauges.\n\n http://indico.cern.ch/contributionDisplay.py?contribId=54&confId=153191 LOCATION:Peniche\, Portugal URL:http://indico.cern.ch/contributionDisplay.py?contribId=54&confId=15319 1 END:VEVENT END:VCALENDAR
