The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade is under construction, to increase luminosity by two orders magnitude during a three-year shutdown, with ultimate goal 8E35 /cm^2 /s luminosity. To exploit increased luminosity, been proposed. A new international collaboration Belle-II, being formed. Technical Design Report presents physics motivation, basic methods accelerator upgrade, as...
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.
We investigate Lefschetz thimble structure of the complexified path-integration in one-dimensional lattice massive Thirring model with finite chemical potential. The is formulated staggered fermions and a compact auxiliary vector boson (a link field), whole set critical points (the complex saddle points) are sorted out, where each point turns out to be one-to-one correspondence singular effective action (or zero fermion determinant). For subset solutions uniform-field subspace, we examine...

The soft mode near the critical end point in phase diagram of two-flavor Nambu--Jona-Lasinio model is investigated within leading ${1/N}_{c}$ approximation, with ${N}_{c}$ being number colors. It explicitly shown by studying spectral function scalar channel that relevant density fluctuation, which coupled quark density, while sigma meson stays massive.
Assuming a tricritical point of two-flavor QCD in the space temperature, baryon number chemical potential, and quark mass, we study change associated soft mode along critical line within Ginzburg-Landau approach Nambu--Jona-Lasinio model. The ordering density chiral is scalar whereas linear combination scalar, number, energy densities becomes proper with finite masses. It shown that eigenmode shifts from sigma-like fluctuation to hydrodynamic at point, where have two densities, densities. We...

The angular dependence of proton polarization in $\ensuremath{\gamma}d\ensuremath{\rightarrow}\mathrm{pn}$ has been measured at photon energies between 400 and 650 MeV. differential-cross-section data are consistently explained by introducing a dibaryon resonance $I({J}^{P})=0({3}^{+}) or 0({1}^{+})$ \ensuremath{\approx} 2360
The Future Circular Collider (FCC) Study is aimed at assessing the physics potential and technical feasibility of a new collider with centre-of-mass energies, in hadron-hadron collision mode, seven times larger than nominal LHC energies. Operating such machine heavy ions an option that being considered accelerator design studies. It would provide, for example, Pb-Pb p-Pb collisions sqrt{s_NN} = 39 63 TeV, respectively, per nucleon-nucleon collision, integrated luminosities above 30 nb^-1...
A bstract For studying small- x gluon saturation in forward dijet production high-energy dilute-dense collisions, the improved TMD (ITMD) factorization formula was recently proposed. In Color Glass Condensate (CGC) framework, it represents leading term of an expansion inverse powers hard scale. It contains leading-twist relevant for small gluon’s transverse momentum k t , but also incorporates all-order resummation kinematical twists, resulting a proper matching to at large . this paper, we...
We demonstrate the violation of kperpendicular factorization for quark production in high energy hadronic collisions. This is quantified color glass condensate framework and studied as a function mass, transverse momentum, saturation scale Q(s), which measure large parton densities. At x values where densities are but leading twist shadowing effects still small, violations kperpendicularkfactorization can be significant--especially lighter quarks. very small x, large, we show that relatively weaker.
We estimate the energy density and gluon distribution associated with classical fields describing early-time dynamics of heavy-ion collisions. In McLerran-Venugopalan model, we first decompose into momentum components exactly, use Wilson line correlators. Then evolve free-field equation, which is justified by dominance ultraviolet modes near collision point. also discuss improvement that occurs inclusion nonlinear terms time evolution. Our numerical results at RHIC are fairly consistent...
We study time evolution of critical fluctuations conserved charges near the QCD point in context relativistic heavy ion collisions. A stochastic diffusion equation is employed order to describe property fluctuation arising from coupling parameter field charges. show that gives rise a possibility probing early through rapidity window dependence second-order cumulant and correlation function It pointed out their nonmonotonic behaviors as functions interval are robust experimental signals for...
