“…In Lednick-Lyuboshitz model, the weight due to the final state interactions (FSIs) of each pair from the phase space is calculated as the square of the properly symmetrizied wavefunction averaged over the total pair spin and the distribution of relative distances of particle emission points in the pair rest frame [25][26][27][28]. For a pair of particles composed of two particles, the calculation process of the correlation function may vary with the variety of particles [29][30][31].…”

The observed heaviest anti-nucleus so far is 4 He which is found in relativistic heavy ion collider in 2011. The yield of 4 Li is four times bigger than that of 4 He according to the thermal model. From previous scattering experiment, we know that the 4 Li has a very short life time about 1.197×10 −22 s. It decays into 3 He and p. In experiment, the correlation function of p− 3 He will offer us a method to observe 4 Li by CPT symmetry. In this paper, we use the blast-wave model and Lednick-Lyuboshitz analytical model to obtain a prediction of the correlation function of p − 3 He with/without 4 Li decay in Au + Au collisions at √ SNN = 200 GeV. The correlation function with 4 Li decay is found to exhibit a peak at k * ≈ 0.073GeV/c. The results offer a guide for the experimental search for 4 Li in relativistic heavy ion collision.

“…Another condition for the separation of pairs can be the sign of k side , k long and k out , the k * π projections onto three perpendicular axes in the longitudinally comoving system (LCMS) where the longitudinal component of the pair momentum vanishes [5]. In the LCMS, the out axis is parallel to the pair velocity, the long axis is the beam axis and the side axis is perpendicular to the other two.…”

Abstract. Femtoscopy analysis allows us to extract information about the properties of particle emission source created after collision. From HBT of two correlated pions one can calculate source sizes; in addition, from the non-identical particle correlations, e.g. pion-kaon femtoscopy, one can obtain information not only about source sizes but the asymmetry in the emission processes of particles of different types as well. Such asymmetry gives knowledge of which kind of particles are emitted first/second and/or from which region of the source. The studies of non-identical particle femtoscopy for different collision energies gives us the opportunity to study how the source size and asymmetry in particle emission depend on the initial conditions of the collision. In these proceedings, we will present STAR results of pion-kaon femtoscopy at mid-rapidity in Au + Au collisions from the Beam Energy Scan program.

“…The corresponding projections of the three-vector r * , the relative distance between the particle freeze-out points in the PRF, are r * out , r * side , and r * long . Due to azimuthal symmetry and symmetry about mid − rapidity: r side = r long = 0 [8]. Thus C + /C ("double ratio"), defined with respect to the signs of k * side and k * long , should not deviate from unity.…”

Abstract. In non-identical particle correlations, e.g. pion-kaon femtoscopy, one can obtain information about source size and asymmetry in emission processes of pions and kaons. Such asymmetry give us knowledge of which type of particles is emitted first/second and/or from which region of the source. The studies of non-identical particle femtoscopy for Beam Energy Scan energies give us the opportunity to study how the source size and asymmetry in particle emission depend on the initial conditions of the collision. It also allows one to examine these parameters in the vicinity of the theoretical critical point. In these proceedings, we present STAR results of pion-kaon femtoscopy at mid-rapidity in Au+Au collisions at √ sNN = 7.7, 19.6 and 39 GeV.
