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 ...
Accelerating solutions of perfect fluid hydrodynamics for initial energy density and life-time measurements in heavy ion collisions
(Sociedade Brasileira de Física, 2007-06-01)
A new class of accelerating, exact, explicit and simple solutions of relativistic hydrodynamics is presented. Since these new solutions yield a finite rapidity distribution, they lead to an advanced estimate of the initial ...

J/psi production in pp collisions at root s=200GeV in the STAR experiment
(INDIAN ASSOC CULTIVATION SCIENCE, 2010)
In this work we present the J/psi measurement in p+p collisions within the STAR collaboration Quarkonium program. This measurements aim to be the baseline measurement of a more comprehensive systematic study of quarkonium ...
Effect of deformed nuclei in hydrodynamic evolution and bulk observables
(Universidade Estadual Paulista (Unesp), 2022-02-04)
Esse trabalho envolve um estudo numérico em colisões relativísticas de íons pesados baseados em modelos hidrodinâmicos. Sabemos que o processo de colisão entre dois núcleos no colisor de ions pesados (RHIC) gera uma ...
NONSTANDARD GAMMA-GAMMA-]L+L- PROCESSES IN RELATIVISTIC HEAVY-ION COLLISIONS
(American Physical Soc, 1991-07-01)
We study lepton pair production in heavy-ion collisions with emphasis on nonstandard contributions to the QED subprocess gamma-gamma --> l+l-. The existence of compositeness of fermions and/or bosons can be tested in this ...

Nonstandard l+l- processes in relativistic heavy-ion collisions
(1991-01-01)
We study lepton pair production in heavy-ion collisions with emphasis on nonstandard contributions to the QED subprocess l+l-. The existence of compositeness of fermions and/or bosons can be tested in this reaction up to ...
A QED description of relativistic Coulomb excitation in heavy ion collisions
(1987-08-01)
A quantum electrodynamical treatment of Coulomb excitation in relativistic heavy ion collisions is presented. It is shown that a subtle interplay between quantum and relativistic kinematical effects induced by the nuclear ...
