In this work, the parton and hadron cascade model (PACIAE) and the dynamically constrained phase space coalescence model (DCPC) are used to investigate the production of hypertriton and antihypertriton in Pb-Pb collisions at s N N = 0.9 , 2.76, 5.02 and 7 TeV. The model parameters are fixed by comparing the PACIAE result with ALICE data on Λ and p...

We study the influence of the centrality definitionCentrality definition and detector efficiency on the net-proton kurtosis for minimum bias AuAu collisions at a beam energy of GeV by using the UrQMD model. We find that different ways of defining the centrality lead to different cumulant ratiosCumulant ratios. Moreover, we demonstrate that the kurt...

We explore the scaling properties of the elliptic and quadrangular flow of deuterons and protons in Au+Au reactions at a beam energy of 1.23 AGeV within the UrQMD approach. These investigations are of great interest for the HADES experiment at GSI that has recently studied the flow of light nuclei. In the present studies, deuterons are formed via p...

We study the influence of the centrality definition and detector efficiency on the net-proton kurtosis for minimum bias Au+Au collisions at a beam energy of $\sqrt{s_{\mathrm{NN}}}= 7.7$ GeV by using the UrQMD model. We find that different ways of defining the centrality lead to different cumulant ratios. Moreover, we demonstrate that the kurtosis...

We explore the directed, elliptic, triangular and quadrangular flow of deuterons in Au+Au reactions at a beam energy of 1.23 AGeV within the UrQMD approach. These investigations are of direct relevance for the HADES experiment at GSI that has recently presented first data on the flow of light clusters in Au+Au collisions at 1.23 AGeV. To address th...
Article
The production of deuterons and heavy clusters such as triton and helium (or even hypertriton) has gained increased attention during the last years. This attention was mainly stimulated by the recent hypertriton data and has led to the question of whether cluster production is driven by coalescence of its constituents or by thermal emission of the...
Article
We explore the rapidity and transverse momentum dependence of collective flow harmonics of deuterons and protons in Au + Au reactions at a beam energy of 1.23 AGeV within the UrQMD approach. These investigations are of direct relevance for the high acceptance di electron spectrometer (HADES) experiment at the GSI Helmholtzzentrum für Schwerionenfor...

Ultrarelativistic quantum molecular dynamics phase-space coalescence calculations for the production of deuterons are compared with available data for various reactions from the Facility for Antiproton and Ion Research energy regime energy regime over the CERN Super Proton Synchrotron–Relativistic Heavy Ion Collider Beam Energy Scan region up to CE...
Preprint
UrQMD phase-space coalescence calculations for the production of deuterons are compared with available data for various reactions from the GSI/FAIR energy regime up to LHC. It is found that the production process of deuterons, as reflected in their rapidity and transverse momentum distributions in p+p, p+A and A+A collisions at a beam energies star...

We study the dependence of the normalized moments of the net-proton multiplicity distributions on the definition of centrality in relativistic nuclear collisions at a beam energy of $\sqrt{s_{\mathrm{NN}}}= 7.7$ GeV. Using the UrQMD model as event generator we find that the centrality definition has a large effect on the extracted cumulant ratios....

... In the present paper we take the second route, because viscous multi-fluid hydrodynamics is not yet available. In [13][14][15], the UrQMD model has recently demonstrated its ability to describe the directed, elliptic and triangular flow data from HADES [16]. This means that the arXiv:2011.04546v1 ...
... The HADES experiment at GSI has recently published data for Au+Au reactions at E lab = 1.23 AGeV [3,4]. This data indicated the creation of very high baryon densities which needed a hard EoS to allow for a description of the flow data up to the 4 th flow harmonic [5][6][7]. On the experimental side, even higher flow harmonic up to 5 th and potentially 6 th order could be analyzed, but still wait for theoretical investigation. While a wealth of data has been available from the HADES and previously FOPI experiments, most of these data where unfortunately taken at different beam energies. ...
... Among other publications, in Refs. [30][31][32], the formation of deuterons was modeled by the phase space coalescence of protons and neutrons. Within this approach, the probability of creating deuterons in a certain momentum space volume is proportional to the numbers of produced neutrons and protons in this volume and to the coalescence parameter B 2 . ...
... The theoretical studies on the production of particles and anti-particles are been going on for years, for example, the coalescence model, thermal model and transport models [9][10][11][12][13][14][15][16][17][18][19][20][21]. In particular, the study of transport phenomena is very important for understanding many OPEN ACCESS EDITED BY fundamental properties [22,23]. The transverse momentum spectrum of particles produced in high-energy collisions is of great research value because it can provide us with key information about the dynamic freezing state of the interacting system [24]. ...
