“…In previous studies, only a spin-independent Wigner function is used to calculate the Wigner phase-space density [45,47] by using a statistical factor G to take into account the spin-isospin degeneracy of light clusters. For example, the spin degeneracy factor for a proton and a neutron to form a deuteron is 3/8.…”

“…These hybrid models have been shown to be effective and reasonable in describing observables of light clusters, such as their multiplicities [41][42][43][44][45] and collective flows [46][47][48][49][50]. In the present study, we adopt a dynamical coalescence model which evaluates the probability of producing a cluster by the overlap of its Wigner phase-space density with daughter nucleons [45,47]. This model is specially useful for studying light clusters which are loosely bound.…”

The spin up-down splitting of collective flows in intermediate-energy heavy-ion collisions as a result of the nuclear spin-orbit interaction is investigated within a spin-and isospin-dependent Boltzmann-Uehing-Uhlenbeck transport model SIBUU12. Using a Skyrme-type spin-orbit coupling quadratic in momentum, we found that the spin splittings of the directed flow and elliptic flow are largest in peripheral Au+Au collisions at beam energies of about 100-200 MeV/nucleon, and the effect is considerable even in smaller systems especially for nucleons with high transverse momenta. The collective flows of light clusters of different spin states are also investigated using an improved dynamical coalescence model with spin. Our study can be important in understanding the properties of in-medium nuclear spin-orbit interactions once the spin-dependent observables proposed in this work can be measured.

“…If this system thermalizes, the thermal pressure will necessarily generate collective transverse expansion [ 1,2]. If the initial state is azimuthally asymmetric, as in semi-central collisions, this property may be reflected in the azimuthal asymmetry of the final state particle distributions.…”

Directed and elliptic flow of protons and positively charged pions has been studied in the target fragmentation region using the Plastic Ball detector in the WA98 experiment. The results exhibit a strong dependence on centrality, rapidity, and transverse momentum. The rapidity dependence can be described by a Gaussian distribution. The model comparisons reveal a large discrepancy of the flow strength obtained from the data and the simulations.

“…The factors account for the statistical spin and isospin projection on the (anti-)deuteron state. The calculation of thet is straight forward, by exchanging the Hulthén parametrization of thed wavefunction with a 3-body harmonic oscilator wavefunction to describe thet [10]. We use the event mixing technique to improve statistics.…”

“…We calculate the deuteron and antideuteron formation probability by projecting the (anti-)nucleon pair phasespace on the (anti-)deuteron wave function via the Wigner-function method as described in [10,11]. The Hulthén parametrization [12] is used to describe the relative part of the (anti-)deuteron wavefunction.…”
