Thermal Duality and Hagedorn Transition from p-adic Strings (2009)
Biswas, Tirthabir, Cembranos, Jose A. R., Kapusta, Joseph I.
We develop the finite temperature theory of p-adic string models. We find that the thermal properties of these non-local field theories can be interpreted either as contributions of standard thermal...
Chiral Symmetry Breaking in a Soft-Wall Model of AdS/QCD (2009)
Kapusta, Joseph I., Kelley, Thomas M., Gherghetta, Tony
We incorporate chiral symmetry breaking in a soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one to separate...
Chiral Symmetry Breaking in Soft-Wall AdS/QCD (2009)
Gherghetta, Tony, Kapusta, Joseph I., Kelley, Thomas M.
We show how to incorporate chiral symmetry breaking in the soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one...
Critical Points in the Linear Sigma Model with Quarks (2008)
Bowman, E. Scott, Kapusta, Joseph I.
We employ a simple effective model to study the chiral dynamics of two flavors of quarks at finite temperature and density. In particular, we determine the phase diagram in the plane of temperature...
Viscous Properties of Strongly Interacting Matter at High Temperature (2008)
Substantial collective flow is observed in collisions between large nuclei at high energy, and the data are well-reproduced by perfect fluid dynamics. In a separate development, calculation of the...
Accelerator Disaster Scenarios, the Unabomber, and Scientific Risks (2008)
The possibility that experiments at high-energy accelerators could create new forms of matter that would ultimately destroy the Earth has been considered several times in the past quarter century....
Low Mass Dimuons Produced in Relativistic Nuclear Collisions (2007)
Ruppert, Jorg, Gale, Charles, Renk, Thorsten, Lichard, Peter, Kapusta, Joseph I.
The NA60 experiment has measured low-mass muon pair production in In-In collisions at 158 A GeV with unprecedented precision. We show that this data is reproduced very well by a dynamical model with...
Cosmological Black Hole Formation due to QCD and Electroweak Phase Transitions (2007)
Kapusta, Joseph I., Springer, Todd
We solve dynamical equations of motion to determine the conditions under which an over-dense region in the early universe will lead to collapse to a black hole, starting from horizon crossing of the...
Strongly Interacting Low Viscosity Matter Created in Heavy Ion Collisions (2007)
Substantial collective flow is observed in collisions between large nuclei at high energy, as evidenced by single-particle transverse momentum distributions and by azimuthal correlations among the...

Barish, Kenneth, Huang, Huan Zhong, Kapusta, Joseph I, Odyniec, Grazyna Janina, Rafelski, Johann, Whitten, Charles A
On the Strongly-Interacting Low-Viscosity Matter Created in Relativistic Nuclear Collisions (2006)
Csernai, Laszlo P., Kapusta, Joseph. I., McLerran, Larry D.
Substantial collective flow is observed in collisions between large nuclei at RHIC (Relativistic Heavy Ion Collider) as evidenced by single-particle transverse momentum distributions and by azimuthal...
From Color Fields to Quark Gluon Plasma (2005)
Fries, Rainer J., Kapusta, Joseph I., Li, Yang
We discuss a model for the energy distribution and the early space-time evolution of a heavy ion collision. We estimate the gluon field generated in the wake of hard processes and through primordial...
Baryonic coherent state formation from small domain disoriented chiral condensates (2002)
Wong, Stephen M. H., Kapusta, Joseph I.
Rare hyperon yields such as the Omega and AntiOmega in heavy ion collision experiments are hard to be reproduced by numerical models. This, in combination with the thermal fit to SPS data, seems to...
Kaon and Pion Fluctuations from Small Disoriented Chiral Condensates (2001)
Gavin, Sean, Kapusta, Joseph I.
Enhancement of omega and antiomega baryon production in Pb+Pb collisions at a c.m. energy of 17 A GeV can be explained by the formation of many small disoriented chiral condensate regions. This...
Primordial Black Holes and Hot Matter (2001)
Microscopic black holes explode with their temperature varying inversely as their mass. Such explosions would lead to the highest temperatures in the present universe, all the way to the Planck...
Quark-Gluon Plasma in the Early Universe (2001)
A QCD phase transition in the early universe could have left inhomogeneities in the baryon to photon ratio and in isospin that might have affected nucleosynthesis later on. At very high temperature...
Will Strangeness Win the Prize? (2000)
Five groups have made predictions involving the production of strange hadrons and entered them in a competition set up by Barbara Jacak, Xin-Nian Wang and myself in the spring of 1998 for the purpose...
Dynamical Evolution of the Scalar Condensate in Heavy Ion Collisions (1999)
Csernai, Laszlo P., Ellis, Paul J., Jeon, Sangyong, Kapusta, Joseph I.
We derive the effective coarse-grained field equation for the scalar condensate of the linear sigma model in a simple and straightforward manner using linear response theory. The dissipative...
Dynamical Formation of Disoriented Chiral Condensates (1996)
Kapusta, Joseph I., Vischer, Axel P.
We study the dynamical formation of disoriented chiral condensates in very high energy nucleus-nucleus collisions using Bjorken hydrodynamics and relativistic nucleation theory. It is the dynamics of...
Inhomogeneous Nucleation of Quark-Gluon Plasma in High Energy Nuclear Collisions (1995)
Kapusta, Joseph I., Vischer, Axel P.
We estimate the probability that a hard nucleon-nucleon collision is able to nucleate a seed of quark--gluon plasma in the surrounding hot and dense hadronic matter formed during a central collision...
Baryon - Antibaryon Production by Disordered Chiral Condensates (1994)
Kapusta, Joseph I., Srivastava, Ajit M.
We investigate the production of baryons and antibaryons in the central rapidity region of high energy nuclear collisions within the framework of the Skyrme model taking into account the effects of...
The Proximal Chiral Phase Transition (1994)
Kapusta, Joseph I., Srivastava, Ajit M.
We consider the form of the chiral symmetry breaking piece of the effective potential in the linear sigma model. Surprisingly, it allows for a second local minimum at both zero and finite...
