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.
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.
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
Fusion and quasifission within the dinuclear system model
Acta Physica Hungarica A) Heavy Ion Physics - Tập 19 - Trang 87-94 - 2004
G. G. Adamian, N. V. Antonenko, A. Diaz-Torres, W. Scheid
The dinuclear system model considers a configuration of two touching nuclei which exchange nucleons. The microscopical justification of the model is presented. The fusion and quasifission processes are described in the reactions of synthesis of heavy and superheavy nuclei. The dependence of evaporation residue cross sections on isotopic composition of colliding nuclei is analyzed. The results agre...... hiện toàn bộ
Medium effects on meson couplings and dilepton spectra
Acta Physica Hungarica A) Heavy Ion Physics - Tập 22 - Trang 29-36 - 2005
Agnieszka Bieniek
The πωπ coupling constant is calculated in a relativistic hadronic framework incorporating nucleons and Δ(1232) isobars. Medium modifications are included. The vertex is analyzed in context of the ω → π 0e+e− and ρ a → π a e+e− Dalitz decays in nuclear matter. A sizeable increase ...... hiện toàn bộ
The Giant Dipole Resonance in the superdeformed143Eu nucleus
Acta Physica Hungarica A) Heavy Ion Physics - Tập 6 Số 1-4 - Trang 83-93 - 1997
A. Bracco, F. Camera, A. Maj, B. Herskind, A. Ataç, P. Bosetti, R. A. Bark, I. G. Bearden, J. J. Gaardhøje, M. Kmiecik, S. Leoni, M. Mattiuzzi, G. Turri
First search for positive strangelets with the E864 spectrometer
Acta Physica Hungarica A) Heavy Ion Physics - Tập 4 - Trang 423-428 - 1996
Kenneth N. Barish
The first search for strangelets conducted by experiment BNL-E864 is presented [1]. The analysis uses over 26.5 million “central” events recorded for the “positive strangelet” search from the first (Fall 1994) run of the experiment. The full apparatus was not installed for this run, but the tracking portion of the apparatus which was present for the 1994 run performed to the expectations of our pr...... hiện toàn bộ
Charm quark energy loss at RHIC
Acta Physica Hungarica A) Heavy Ion Physics - Tập 21 - Trang 365-369 - 2004
Magdalena Djordjevic, Mikios Gyulassy
Heavy quark energy loss in a hot QCD plasma is computed taking into account the competing effects due to suppression of zeroth order gluon radiation below the plasma frequency and the enhancement of gluon radiation due to first order medium induced bremsstrahlung. The results suggest a surprising degree of cancellation between the two medium effects for charm quarks and provide a possible explanat...... hiện toàn bộ
Molecular-orbital structure in Be isotopes
Acta Physica Hungarica A) Heavy Ion Physics - Tập 13 - Trang 153-156 - 2001
Naoyuki Itagaki, Shigeto Okabe, Kiyomi Ikeda
The structure of 12Be is investigated using a microscopic α+α+4n model based on the molecular-orbit (MO) model. It is shown that the remark-able α-clustering and the contribution of the spin-orbit interaction make the binding of the state with the (3/2−)2(1/2+)2 configuration for the valence neutrons properly stronger in comparison with the closed p-shell (3/2−)2(1/2−)2 configuration. The molecula...... hiện toàn bộ
Uncertainties in air showers from small-x pQCD mini-jets
Acta Physica Hungarica A) Heavy Ion Physics - Tập 27 - Trang 315-318 - 2006
L. Portugal
To investigate uncertainties in air shower simulations caused by the small-x regime, a model including leading-twist hard pQCD plus soft processes was built, which are separated by an energy dependent transverse momentum cut-off. We provide a fit of the cut-off to the total pp cross section for different PDFs using the eikonal formalism and show that for modern PDF sets there is only a small uncer...... hiện toàn bộ
