Can dissipation prevent explosive decomposition in high-energy heavy ion collisions?
(Elsevier B.V., 2005-05-19)
We discuss the role of dissipation in the explosive spinodal decomposition scenario of hadron production during the chiral transition after a high-energy heavy ion collision. We use a Langevin description inspired by ...
Photon-photon and pomeron-pomeron processes in peripheral heavy ion collisions
(2000-06-01)
We estimate the cross sections for the production of resonances, pion pairs, and a central cluster of hadrons in peripheral heavy-ion collisions through two-photon and double-pomeron exchange, at energies that will be ...
Nonequilibrium dynamics of quantum fields
(Elsevier B.V., 2007-02-01)
The nonequilibrium effective equation of motion for a scalar background field in a thermal bath is studied numerically. This equation emerges from a microscopic quantum field theory derivation and it is suitable to a ...
Thermal photon production in Au plus Au collisions: Viscous corrections in two different hydrodynamic formalisms
(Elsevier B.V., 2011-02-01)
We calculate the spectra of produced thermal photons in Au + Au collisions taking into account the nonequilibrium contribution to photon production due to finite shear viscosity. The evolution of the fireball is modeled ...
Ultra peripheral heavy ion collisions and the energy dependence of the nuclear radius
(Elsevier B.V., 2004-02-19)
To estimate realistic cross sections in ultra peripheral heavy ion collisions we must remove effects of strong absorption. One method to eliminate these effects make use of a Glauber model calculation, where the nucleon-nucleon ...
Hadronic physics in peripheral heavy Ion collisions
(Sociedade Brasileira de Física, 2002-12-01)
We discuss the production of hadronic resonances in very peripheral heavy ion collisions, where the ions collide with impact parameter larger than twice the nuclear radius and remain intact after the collision. We compare ...
Searching for anomalous Higgs couplings in peripheral heavy ion collisions at the LHC
(Elsevier B.V., 2001-01-11)
We investigate the sensitivity of the heavy ion mode of the LHC to anomalous Higgs boson couplings to photons, H gamma gamma, through the analysis of the processes gamma gamma --> b (b) over bar and gamma gamma --> gamma ...
Can we observe the radion and Higgs signals in peripheral heavy ion collisions?
(Sociedade Brasileira de Física, 2004-03-01)
We investigate the sensitivity of the heavy ion mode of the LHC to Higgs boson and Radion production via photon-photon fusion through the analysis of the processes gg -> gg, gg ->, and gg ® ggin peripheral heavy ion ...
Searching for squeezed particle-antiparticle correlations in high-energy heavy-ion collisions
(Amer Physical Soc, 2010-09-24)
Squeezed correlations of particle-antiparticle pairs were predicted to exist if the hadron masses were modified in the hot and dense medium formed in high-energy heavy-ion collisions. Although well-established theoretically, ...
Radion and Higgs signals in peripheral heavy ion collisions at the LHC
(Elsevier B.V., 2002-08-01)
We investigate the sensitivity of the heavy ion mode of the LHC to Higgs boson and Radion production via photon-photon fusion through the analysis of the processes gammagamma --> gammagamma, gammagamma --> b (b) over bar, ...
