“…After the cancellation of the Coulomb effect, one now finds notable enhancement of C SL (q) above 1 at small q and depletion below 1 at q = (20− 80) MeV due to the strong pΩ attraction accommodating a bound state. In response to the theoretical proposal in [17], the STAR collaboration at RHIC has reported a first measurement of pΩ correlation in Au+Au collisions [20]. Although the statistics of the data are not sufficient to draw a definitive conclusion, the measured C(q) and C SL (q) show similar tendency with Fig.6 in the present paper.…”

Probing ΩΩ and pΩ dibaryons with femtoscopic correlations in relativistic heavy-ion collisions

et al. 2020

The momentum correlation functions of baryon pairs, which reflects the baryon-baryon interaction at low energies, are investigated for multi-strangeness pairs (ΩΩ and N Ω) produced in relativistic heavy-ion collisions. We calculate the correlation functions based on an expanding source model constrained by single-particle distributions. The interaction potentials are taken from those obtained from recent lattice QCD calculations at nearly physical quark masses. Experimental measurements of these correlation functions for different system sizes will help to disentangle the strong interaction between baryons and to unravel the possible existence of strange dibaryons.

“…Above all, the progress of the N Ω searches in experiment attracted more and more attention for its accessible. Very recently, the measurement of the pΩ correlation function was conducted in Au + Au collisions by the STAR experiment at the Relativistic Heavy-Ion Collider (RHIC) [13], and the result indicated that the scattering length is positive for the pΩ interaction and favored the pΩ bound state hypothesis. On the theoretical side, the N Ω state has been investigated by several groups.…”

Prediction of NΩ -like dibaryons with heavy quarks

Possible N Ω-like dibaryons N Ωccc and N Ω bbb with quantum numbers IJ P = 1 2 2 + are investigated within the framework of quark delocalization color screening model. We find both of these two states are bound, and the binding energy increases as the quarks of the system become heavier. The attraction between N and Ωccc (or Ω bbb ) mainly comes from the kinetic energy term due to quark delocalization and color screening. The effect of the channel-coupling provides more effective attraction to N Ωccc and N Ω bbb systems. Besides, the scattering length, the effective range, and the binding energy, obtained from the calculation of the low-energy scattering phase shifts, also supports the existence of the N Ωccc and N Ω bbb states. All these properties can provide necessary information for experimental search for the N Ω-like dibaryons with heavy quarks. And the experimental progress can also check the mechanism of the intermediate-range attraction of the baryon-baryon interaction in quark models.

“…Theoretically, the correlation function reflects the two-body interac-tions through the wave function with a suitable boundary condition. On the experimental side, correlation functions have been measured for pΛ [8,9], ΛΛ [9,10], pΞ − [11], pΩ [12], pK − [13], and pΣ 0 [14] pairs. These data have been used to constrain the pairwise interactions [7,[15][16][17][18][19].…”

K−p Correlation Function from High-Energy Nuclear Collisions and Chiral SU(3) Dynamics

et al. 2020

View full text Add to dashboard Cite

The two-particle momentum correlation function of a K − p pair from high-energy nuclear collisions is evaluated in theKN -πΣ-πΛ coupled-channels framework. The effects of all coupled channels together with the Coulomb potential and the threshold energy difference between K − p andK 0 n are treated completely for the first time. Realistic potentials based on the chiral SU(3) dynamics are used which fit the available scattering data. The recently measured correlation function is found to be well reproduced by allowing variations of the source size and the relative weight of the source function of πΣ with respect to that ofKN . The predicted K − p correlation function from larger systems, which is less affected by the πΣ source function, indicates that the investigation of its source size dependence is useful in providing further constraints in the study of theKN interaction.
