“…34. Figure 35 shows the experimentally extracted B 2 and B 3 (mainly from central collisions of these publications [170,171,172,173,174,175,176,75,76,77,78]) as a function of the centerof-mass energy in the heavy-ion collisions. One finds that the coalescence parameters are rather insensitive on the collision energy in heavy-ion collisions since all data points of B 2 lie around 10 −3 and B 3 between 10 −7 and 10 −6 .…”

Loosely-bound objects produced in nuclear collisions at the LHC

Loosely-bound objects such as light nuclei are copiously produced in proton-proton and nuclear collisions at the Large Hadron Collider (LHC), despite the fact that typical energy scales in such collisions exceed the binding energy of the objects by orders of magnitude. In this review we summarise the experimental observations, put them into context of previous studies at lower energies, and discuss the underlying physics. Most of the data discussed here were taken by the ALICE Collaboration during LHC Run1, which started in 2009 and ended in 2013. Specifically we focus on the production of (anti-)nuclei and (anti-)hypernuclei. Also included are searches for exotic objects like the H-dibaryon, a possible uuddss hexaquark state, or also a possible bound state of a Λ hyperon and a neutron. Furthermore, the study of hyperon-nucleon and hyperonhyperon interactions through measurements of correlations are briefly discussed, especially in connection with the possible existence of loosely-bound states composed of these baryons. In addition, some results in the strange and charmed hadron sector are presented, to show the capabilities for future measurements on loosely-bound objects in this direction. Finally, perspectives are given for measurements in the currently ongoing Run2 period of the LHC and in the future LHC Run3.

“…An experimental effort must be obviously accompanied by theoretical studies. The yields of 4 He and 5,6 Li have been already computed in the coalescence model [33] but there is still some space for improvements. In particular, a nontrivial internal structure of 4 Li should be properly incorporated into the model calculations.…”

“…Production of light nuclei and antinuclei in relativistic heavy-ion collisions has been experimentally studied in a broad range of collision energies from AGS [1][2][3][4], SPS [5][6][7][8][9][10], to RHIC [11][12][13][14] and LHC [15]. The light nuclei are expected to form at a late stage of high-energy collision called the kinetic freeze-out when a fireball -the system of hot and dense matter created at the collision early stage -decays and emitted hadrons are flying away interacting only with their close neighbors in the phase-space.…”

Production of Light Nuclei in the Thermal and Coalescence Models

The thermal model properly describes the production yields of light nuclei in relativistic heavy-ion collisions even so the loosely bound sizable nuclei cannot exist in the dense and hot hadron gas at a chemical freeze-out. Within the coalescence model, light nuclei are formed at the latest stage of nuclear collisions -a kinetic freeze-out -due to final state interactions. After discussing the models, we derive simple analytic formulas and, using model parameters directly inferred from experimental data, we show that the thermal and coalescence model predictions are quantitatively close to each other. A possibility to falsify one of the two models is suggested.

“…Up to now, light (anti)nuclei production has been studied extensively only in the energy range below √ s N N ≈ 20 GeV at the AGS [23][24][25][26] and SPS [27][28][29][30]. In Ref.…”

Production of d, t, and 3 He nuclei in central Pb + Pb interactions was studied at five collision energies ( √ s NN = 6.3, 7.6, 8.8, 12.3, and 17.3 GeV) with the NA49 detector at the CERN Super Proton Synchrotron. Transverse momentum spectra, rapidity distributions, and particle ratios were measured. Yields are compared to predictions of statistical models. Phase-space distributions of light nuclei are discussed and compared to those of protons in the context of a coalescence approach. The coalescence parameters B 2 and B 3 , as well as coalescence radii for d and 3 He were determined as a function of transverse mass at all energies.
