Three-nucleon forces (3NF) are investigated from two-flavor lattice QCD simulations. We utilize the Nambu-Bethe-Salpeter (NBS) wave function to determine two-nucleon forces (2NF) and 3NF in the same f...
Layers of Cold Dipolar Molecules in the Harmonic Approximation
Harmonic Approximation Dipolar Molecules
2011/7/21
We consider the N-body problem in a layered geometry containing cold polar molecules with dipole moments that are polarized perpendicular to the layers. A harmonic approximation is used to simplify th...
We give a breezy, qualitative overview of some of our recent results on studying jet stopping in strongly-coupled plasmas using gauge-gravity duality. Previously, people have found that the maximum st...
Thermodynamics and Instabilities of a Strongly Coupled Anisotropic Plasma
Thermodynamics Instabilities Anisotropic Plasma
2011/7/21
We extend our analysis of a IIB supergravity solution dual to a spatially anisotropic finite-temperature N=4 super Yang-Mills plasma. The solution is static, possesses an anisotropic horizon, and is c...
Form factors in lattice QCD
factors lattice QCD
2011/7/21
Lattice simulations of QCD have produced precise estimates for the masses of the lowest-lying hadrons which show excellent agreement with experiment.
We determine the value of the omega -rho- pi mesons coupling (g_{omega rho pi}), in the context of the vector meson dominance model, from radiative decays, the omega -> 3 pi decay width and the e^+e^-...
Neutrino-less Double Beta Decay and Particle Physics
Neutrino-less Double Beta Decay Particle Physics
2011/7/21
We review the particle physics aspects of neutrino-less double beta decay. This process can be mediated by light massive Majorana neutrinos (standard interpretation) or by something else (non-standard...
Direct Photon Production in Proton-Nucleus and Nucleus-Nucleus Collisions
direct photons nuclear suppression gluon shadowing
2011/7/21
Prompt photons produced in a hard reaction are not accompanied with any final state interaction, either energy loss or absorption. Therefore, besides the Cronin enhancement at medium transverse moment...
The thermal model on the verge of the ultimate test: particle production in Pb-Pb collisions at the LHC
ultimate test thermal model on the verge Pb-Pb collisions
2011/7/21
We investigate the production of hadrons in nuclear collisions within the framework of the thermal (or statistical hadronization) model. We discuss both the ligh-quark hadrons as well as charmonium an...
Equation of state at finite baryon density based on lattice QCD
lattice QCD baryon density Equation of state
2011/7/21
We employ the lattice QCD data on Taylor expansion coefficients to extend our previous parametrization of the equation of state to finite baryon density.
Heavy-Quark Diffusion and Hadronization in Quark-Gluon Plasma
Heavy Quark Diffusion Quark Gluon Plasma Quark Recombination
2011/7/20
We calculate diffusion and hadronization of heavy quarks in high-energy heavy-ion collisions implementing the notion of a strongly coupled quark-gluon plasma in both micro- and macroscopic components....
The flow of charm is calculated in 2+1 ideal hydrodynamics by introducing the charge of $c\bar{c}$ pair assuming that the number of $c\bar{c}$ pairs is conserved in relativistic heavy-ion collisions.
Second-order quasiparticle interaction in nuclear matter with chiral two-nucleon interactions
Second-order quasiparticle interaction
2011/7/20
We employ Landau's theory of normal Fermi liquids to study the quasiparticle interaction in nuclear matter in the vicinity of saturation density. Realistic low-momentum nucleon-nucleon interactions ev...

2011/7/20
Shear and bulk viscosity-to-entropy density ratios are calculated for the pure gluon matter in a non-equilibrium mean-field quasiparticle approach within the relaxation time approximation. We study ho...

In this paper we discuss a formulation of relativistic quantum mechanics that uses Euclidean Green functions or generating functionals as input.
