“…The other is to use light nuclei to study the space-time structure of the emission source in relativistic heavy ion collisions since they are likely produced at kinetic freeze out via nucleon coalescence, complimenting the method using the HBT interferometry [7,8] of particles emitted at freeze out. The use of the coalescence model for studying light nuclei production has a long history with applications in heavy-ion collisions at both intermediate [9][10][11][12] and high energies [13,14] as well as at relativistic energies [15][16][17][18][19]. In most applications of the coalescence model, the energy spectra for clusters are simply given by the product of the spectra of their constituent nucleons multiplied by an empirical coalescence parameter.…”

Using the coalescence model based on the phase-space distributions of protons, neutrons, Lambdas and their antiparticles from a multiphase transport (AMPT) model, we study the production of deuteron, triton, helium 3, hypertriton, hyperhelium 3 and their antinuclei in Pb+Pb collisions at √ sNN = 2.76 TeV. The resulting transverse momentum spectra, elliptic flows and coalescence parameters for these nuclei are presented and compared with available experimental data. We also show the constituent number scaled elliptic flows of these nuclei and discuss their implications.

“…However, deviation of the scaling of the order of 20% is observed for + V 2 from ALICE. that light (anti)nuclei might have formed via coalescence of (anti)nucleons at a later stage of the evolution at RHIC energies for / up to 1.5 GeV/c [22][23][24][25][26][27][28][29][30][31][32]. However, this simple picture of coalescence may not be holding for ALICE experiment at LHC energies.…”

“…However, the blast-wave model seems to successfully reproduce the + V 2 from ALICE. The low relative production of light nuclei compared to identified nucleons at RHIC collisions energies supports the procedure of light nuclei production via coalescence mechanism [22][23][24][25][26][27][28][29][30][31][32]. However, the success of blast-wave model in reproducing the nuclei V 2 at LHC and moderate success at RHIC suggest that the light nuclei production is also supported by thermal process [17][18][19][20][21].…”

“…However, due to their small (∼ few MeV) binding energies, the directly produced nuclei or antinuclei are likely to break up in the medium before escaping. The second mechanism is via final state coalescence of produced (anti)nucleons or from transported nucleons [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The quark coalescence as a mechanism of hadron production at intermediate transverse momentum has been well established by studying the number of constituent quarks (NCQ) scaling for V 2 of identified hadrons measured at RHIC [37][38][39][40][41][42][43][44][45].…”

We present a review of the measurements of elliptic flow (V 2 ) of light nuclei ( , , , 3 He, and 3 He) from the RHIC and LHC experiments. Light (anti)nuclei V 2 have been compared with that of (anti)proton. We observed a similar trend in light nuclei V 2 to that in identified hadron V 2 with respect to the general observations such as dependence, low mass ordering, and centrality dependence. We also compared the difference of nuclei and antinuclei V 2 with the corresponding difference of V 2 of proton and antiproton at various collision energies. Qualitatively they depict similar behavior. We also compare the data on light nuclei V 2 to various theoretical models such as blast-wave and coalescence. We then present a prediction of V 2 for 3 He and 4 He using coalescence and blast-wave models.

“…However, nuclei are believed to be formed in final state interactions between nucleons as a result of coalescence [1], when they are in same phase space. Considering the momentum space, the probability density of nuclei formation of mass number A is proportional to the A th power of protons density [2][3][4].…”

The study of light nuclei production in different interactions at 4.2 AGeV/c

et al. 2016

View full text Add to dashboard Cite

Average multiplicity of light nuclei produced in different interactions at 4.2A GeV/c is studied as a function of centrality. A change in multiplicity is observed with increase in the mass of projectile. In 12 CC-interactions an unexpected increase in the multiplicity is seen for the most central events. These measurements are compared with the predictions of Cascade and Fritiof Models, which fail to account for the experimentally observed effects. In case of 12 CC, it is suggested that the inclusion of nuclear coalescence effect can be an explanatory reason for the differences between the experimental measurements and the models' predictions.
