The Masses

Abstract The thermal and coalescence models both describe well yields of light nuclei produced in relativistic heavy-ion collisions at LHC. We propose to measure the yield of $$^4\mathrm{Li}$$ 4 Li and compare it to that of $$^4\mathrm{He}$$ 4 He to falsify one of the models. Since the masses of $$^4\mathrm{He}$$ 4 He and $$^4\mathrm{Li}$$ 4 Li are almost equal, the yield of $$^4\mathrm{Li}$$ 4 Li is about 5 times bigger than that of $$^4\mathrm{He}$$ 4 He in the thermal model because of different numbers of spin states of the two nuclides. Their internal structures are, however, very different: the alpha particle is well bound and compact while $$^4\mathrm{Li}$$ 4 Li is weakly bound and loose. Consequently, the ratio of yields of $$^4\mathrm{Li}$$ 4 Li to $$^4\mathrm{He}$$ 4 He is significantly smaller in the coalescence model and it strongly depends on the collision centrality. Since the nuclide $$^4\mathrm{Li}$$ 4 Li is unstable and it decays into $$^3\mathrm{He}$$ 3 He and p, the yield of $$^4\mathrm{Li}$$ 4 Li can be experimentally obtained through a measurement of the $$p\!-\!^3\mathrm{He}$$ p - 3 He correlation function. The function carries information not only about the yield of $$^4\mathrm{Li}$$ 4 Li but also about the source of $$^3\mathrm{He}$$ 3 He and allows one to determine through a source-size measurement whether of $$^3\mathrm{He}$$ 3 He is directly emitted from the fireball or it is formed afterwards. We compute the correlation function taking into account the s-wave scattering and Coulomb repulsion together with the resonance interaction responsible for the $$^4\mathrm{Li}$$ 4 Li nuclide. We discuss how to infer information about an origin of $$^3\mathrm{He}$$ 3 He from the correlation function, and finally a method to obtain the yield of $$^4\mathrm{Li}$$ 4 Li is proposed.

We present a review of the measurements of elliptic flow (v2) of light nuclei (d, d¯, t, He3, and He¯3) from the RHIC and LHC experiments. Light (anti)nuclei v2 have been compared with that of (anti)proton. We observed a similar trend in light nuclei v2 to that in identified hadron v2 with respect to the general observations such as pT dependence, low pT mass ordering, and centrality dependence. We also compared the difference of nuclei and antinuclei v2 with the corresponding difference of v2 of proton and antiproton at various collision energies. Qualitatively they depict similar behavior. We also compare the data on light nuclei v2 to various theoretical models such as blast-wave and coalescence. We then present a prediction of v2 for He3 and He4 using coalescence and blast-wave models.
