“…And then the dynamically constrained phase-space coalescence (DCPC) model [36] is applied to deal with the production and properties of light (anti-)nuclei (d, d). Some previous satisfactory results of light (anti-)nuclei production for both pp and A-A collisions in the relativistic energy region, including transverse momentum distribution, energy dependence, scaling property, centrality dependence etc., were obtained by using this couple models [36][37][38][39][40][41][42][43]. Here we will try using this mentioned method to investigate the properties of nuclear modification factors (R AA ) of (anti-)hadrons and (anti-)deuteron in Pb-Pb collisions at √ s NN = 2.76 TeV.…”

The nuclear modification factors (RAA) of π ± , p(p), and d( d) with |y| < 0.5, pT < 6.0 GeV/c in peripheral (40-60%) and central (0-10%) Pb-Pb collisions at √ sNN = 2.76 TeV have been studiedusing the the parton and hadron cascade (PACIAE) model plus the dynamically constrained phasespace coalescence (DCPC) model. It is found that the distribution of RAA of light (anti-)nuclei d is similar to that of hadrons (π, p), and the distribution of anti-particles is the same as that of particles. The suppression of high-pT particles strongly depends on event centrality and mass of the particles, i.e the central collision is more suppressed than the peripheral collision. Besides, the yield ratios, double ratios R D AA of ( d to p, p to π − , d to p, p to π + ), and the coalescence parameter B2 for (d, d) in pp, central and peripheral Pb-Pb collisions are discussed, respectively. It is observed that the yield ratios and R D AA of d to p and p to π − are also the same with the corresponding values of d to p and p to π + in three different collision systems, respectively, suggesting that the suppressions of matter (π + , p, d) and the corresponding antimatter (π − , p, d) has the same character and performance. Our results are comparable to those of experimental data.

“…Some researches use the coalescence + blast-wave method [15][16][17], or a multiphase transport(AMPT) model [18] and UrQMD model + thermal model [19] to study the production of light nuclei and anti-nuclei in high energy nuclear-nuclear collisions. A dynamically constrained phase-space coalescence model (DCPC) [20,21] was proposed and was used to investigate the production of light nuclei (anti-nuclei) [22,23] in high energy pp collisions [24] and nuclei-nuclei (Pb-Pb [25], and Au-Au [26], Cu-Cu [27]) collisions, in which the final state hadrons produced within the parton and hadron cascade (PACIAE) model [28].…”

The production of light (anti-)nuclei and (anti-)hypertriton is investigated using the dynamically constrained phase space coalescence model (DCPC), based on the hadronic final states generated by the parton and hadron cascade model (PACIAE) in pp collisions at √ s = 0.9, 2.76, and 7 TeV, within pT <3.0 GeV/c and |y| <0.5 acceptances. The ALICE data of d and d yields, ratios, and the transverse momentum distribution are well reproduced with the corresponding PACIAE+DCPC results. The yields, ratios, and the transverse momentum distribution of 3 He, 3 He, 3 ΛH , and 3 Λ H were predicted. Furthermore, it is found that the yields of light nuclei and anti-nuclei depend on the mass number A of the matter produced, i.e., their yields decrease rapidly as the increase of mass number. The strangeness population factor S3 = ( 3 Λ H/ 3 He)/(Λ/p) was found to be about 0.7 ∼ 0.8, and was compatible with the experimental data.

The nuclear modification factors ($$R_{AA}$$ R AA ) of d and $$\bar{d}$$ d ¯ have been studied using the parton and hadron cascade model plus the dynamically constrained phase space coalescence model in peripheral (40–60%) and central (0–5%) Pb–Pb collisions at $$\sqrt{s_{NN}}=2.76\,\hbox {TeV}$$ s NN = 2.76 TeV with $$|y|<0.5, p_T<20.0 \,\hbox {GeV}/\hbox {c}$$ | y | < 0.5 , p T < 20.0 GeV / c . It is found that the $$R_{AA}$$ R AA of $$d, \bar{d}$$ d , d ¯ is similar to that of hadrons ($$\pi ^\pm , p, \bar{p}$$ π ± , p , p ¯ ) and the $$R_{AA}$$ R AA of antiparticles is the same as that of particles. The suppression effect of d is more significant than that of baryons and mesons in the high-$$p_T$$ p T region. The suppression of $$R_{AA}$$ R AA at high-$$p_T$$ p T strongly depends on event centrality and mass of the particles, i.e., the central collision is more suppressed than the peripheral collision. Besides, the yield ratios and double ratios for different particle species, and the coalescence parameter $$B_2$$ B 2 for ($$d, \bar{d}$$ d , d ¯ ) in pp and Pb–Pb collisions are discussed, respectively. It is observed that the yield ratios and double ratios of d to p and p to $$\pi $$ π are similar to those of their anti-particles in three different collision systems, suggesting that the suppressions of matter ($$\pi ^{+}, p, d$$ π + , p , d ) and the corresponding antimatter ($$\pi ^{-},\bar{p},\bar{d}$$ π - , p ¯ , d ¯ ) are around the same level.
