Matching Stages of Heavy Ion Collision Models [PDF]

open access: yes, 2010
Heavy ion reactions and other collective dynamical processes are frequently described by different theoretical approaches for the different stages of the process, like initial equilibration stage, intermediate locally equilibrated fluid dynamical stage ...

Antihyperon-Production in Relativistic Heavy Ion Collision [PDF]

open access: yes, 2000
Recently it has been shown that the observed antiproton yield in heavy-ion collisions at CERN-SpS energies can be understood by multi-pionic interactions which enforce local chemical equilibrium of the antiprotons with the nucleons and pions.

Comments About the Electromagnetic Field in Heavy-Ion Collisions

open access: yes, 2013
In this short article we discuss the properties of electromagnetic fields in heavy-ion collisions and consequences for observables. We address quantitatively the issue of the magnetic field lifetime in a collision including the electric and chiral ...

Three-stage classical molecular dynamics model for simulation of heavy-ion fusion

open access: yesEPJ Web of Conferences, 2015
A three-stage Classical Molecular Dynamics (3S-CMD) approach for heavy-ion fusion is developed. In this approach the Classical Rigid-Body Dynamics simulation for heavy-ion collision involving light deformed nucleus is initiated on their Rutherford ...

Study of exclusive photoproduction of charmonium in ultra-peripheral lead-lead collisions

open access: yesJournal of High Energy Physics, 2023
The cross-sections of exclusive (coherent) photoproduction J/ψ and ψ(2S) mesons in ultra-peripheral PbPb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV are measured using a data sample corresponding to an integrated luminosity of 228 ±

Impact-parameter dependence of K-shell ionisation in slow collisioons of near-symmetric relitivistic atoms [PDF]

open access: yes, 1982
. The total K vacancy production probability of both collision partners in a heavy-ion-atom collision is calculated, assuming that two processes contribute, a single-collision process where 2po and 2pa vacancies are created by direct ionisation of the ...

Anisotropy of photon production: Initial eccentricity or magnetic field

open access: yes, 2013
Recent measurements of the azimuthal anisotropy of direct photons in heavy-ion collisions at the energies of RHIC show that it is of the same order as the hadronic one. This finding appears to contradict the expected dominance of photon production from a

Electromagnetic probes in heavy-ion collisions [PDF]

open access: yesEPJ Web of Conferences
Electromagnetic probes such as photons and dileptons (l+l−) are a unique tool to study the space-time evolution of the hot and dense matter created in heavy-ion collisions, since they are emitted at all stages of the collision with negligible final-state

Triggering on Hard Probes in Heavy-Ion Collisions with the CMS Experiment at the LHC [PDF]

open access: yes, 2009
Studies of heavy-ion collisions at the LHC will benefit from an array of qualitatively new probes not readily available at lower collision energies. These include fully formed jets at ET > 50 GeV, Z0's and abundantly produced heavy flavors.
