Light front approach to correlations in hot quark matter
Acta Physica Hungarica A) Heavy Ion Physics - Tập 27 - Trang 379-382 - 2006
S. Strauß, M. Beyer, S. Mattiello
We investigate two-quark correlations in hot and dense quark matter. To this end we use the light front field theory extended to finite temperature T and chemical potential μ. Therefore it is necessary to develop quantum statistics formulated on the light front plane. As a test case for light front quantization at finite T and μ we consider the NJL model. The solution of the in-medium gap equation... hiện toàn bộ
Đo lường tính chất của dòng hạt và sự điều chỉnh của chúng trong các vụ va chạm ion nặng Dịch bởi AI
Acta Physica Hungarica A) Heavy Ion Physics - Tập 24 - Trang 291-297 - 2014
Jan Rak
Tính chất của các dòng hạt được sản xuất trong các vụ va chạm p+p, d+Au và Au+Au tại √{s_NN} = 200 GeV tại RHIC được thảo luận. Sử dụng phương pháp tương quan hai hạt, độ rộng góc và năng suất của các đỉnh tương quan cùng phía và ngược phía được nghiên cứu.

Cluster interpretation of highly deformed nuclear states
Acta Physica Hungarica A) Heavy Ion Physics - Tập 18 - Trang 311-316 - 2003
G. G. Adamian, A. V. Andreev, N. V. Antonenko, S. P. Ivanova, N. Nenoff, W. Scheid, T. M. Shneidman
New methods to identify the high- and low-spin HD cluster states are suggested.
Relativistic lattice gas hydrodynamics
Acta Physica Hungarica A) Heavy Ion Physics - Tập 1 - Trang 149-155 - 1995
N. L. Balazs, D. Strottman
Non-relativistic cellular automata can model non-relativistic hydrodynamical flows. In this article we show that if the hopping occurs on a space-time lattice which is generated by discrete subgroups of the Poincaré group and if the collision rules embody the relativistic conservation laws, we can modelrelativistic flows. The simplest version of the relativistic model is formally isomorphic with t... hiện toàn bộ
The Isoscalar Giant Dipole Resonance: Where we are and where we are headed
Acta Physica Hungarica A) Heavy Ion Physics - Tập 13 - Trang 31-40 - 2001
Umesh Garg
Over the past few years, very good evidence has emerged for the Isoscalar Giant Dipole Resonance from small-angle inelastic scattering of α particles between 50–100 MeV/nucleon. A reconciliation between the available theoretical predictions and the experimental results still remains far from satisfactory, however, and there are interesting implications of the observed ISGDR strengths on the experi... hiện toàn bộ
Directed and elliptic flow in 197Au+197Au at intermediate energies

Sfienti, B. Tamain, W. Trautmann, A. Trzciński, K. Turzó, E. Vient, M. Vigilante, C. Volant, B. Zwiegliński
Directed and elliptic flow for the 197Au+197Au system at incident energies between 40 and 150 MeV per nucleon has been measured using the INDRA 4π multi-detector. For semi-central collisions, the excitation function of elliptic flow shows a transition from in-plane to out-of-plane emission at around 100 MeV per nucleon. The directed flow changes sign at a bombarding energy between 50 and 60 MeV pe... hiện toàn bộ
Some aspects of the Károlyházy model of quantum mechanics in the light of Wigner’s Heritage
Acta Physica Hungarica A) Heavy Ion Physics - Tập 19 - Trang 333-336 - 2004
Andor Frenkel
The lower bound of the length of a time interval, obtained by Károlyházy, is compared with the accuracy of a quantum clock investigated by Wigner and Salecker.
Inflation of fireballs, the gluon wind and the homogeneity of the HBT radii at RHIC
Acta Physica Hungarica A) Heavy Ion Physics - Tập 17 - Trang 281-293 - 2003
T. Csörgő, J. Zimányi
We solve analytically the ellipsoidally expanding fireball hydrodynamics with source terms in the momentum and energy equations, using the non-relativistic approximation. We find that energy transport for high-p tjets of gluons to the medium leads to a transient, exponential inflation of the fireballs created in high energy heavy ion collisions. In this transient, inflatory period, the slopes of t... hiện toàn bộ
RHIC Physics with the Parton Cascade Model
Acta Physica Hungarica A) Heavy Ion Physics - Tập 24 - Trang 45-50 - 2014
Steffen A. Bass, Berndt Müller, Dinesh K. Srivastava
We discuss the Parton Cascade Model and it's application to RHIC physics. In particular, we focus on an analysis of the net-baryon number rapidity distribution and on direct photon emission.
High-p T hadron-hadron correlations in vacuum and in matter
Acta Physica Hungarica A) Heavy Ion Physics - Tập 27 - Trang 97-104 - 2006
A. Majumder
Two-particle correlations within a single jet produced in deeply inelastic scattering (DIS) off a large nucleus as well as in heavy-ion collisions are studied. This is performed within the framework of the medium modi fied dihadron fragmentation functions. The modification occurs due to gluon bremsstrahlung induced by multiple scattering. The modified fragmentation functions for dihadrons are foun... hiện toàn bộ
