... Femtoscopy of nuclei has also become possible in which deuteron or more massive particles have been used. Recently, femtoscopy studies involving proton and deuteron pairs have been carried out in high-multiplicity p + p collisions at √ s = 13 TeV by the ALICE [28] experiment, in Au + Au collisions at √ s NN = 3 GeV measured by the STAR experiment [29], and in Ag + Ag collisions at √ s NN = 2.55 GeV by the HADES experiment [30]. ...

Two-body femtoscopy approach to the proton-deuteron correlation function

... The pseudodata tested here is based on polarisation observables of the γ + p → K 0 + Σ + reaction [10], whose angular-dependent parts are sums of Legendre polynomials. It was assumed for testing purposes that the energydependent part consists of Gaussians, which are dependent on the order of Legendre polynomial. ...

Data-driven Approach for Interpolation of Sparse Data

... Compared with protons, pions and kaons have smaller ∆(dv 1 /dy) magnitudes, which is understandable in view of factors such as mean p T and the formation time. A companion STAR analysis [66] assumes the coalescence sum rule using combinations of hadrons without transported quarks and concludes that the presence of the EM-field dominated by the Hall effect in mid-central events explains the observed v 1 splitting. The combined inference from Ref. [66] and the current work is that a competition between the Hall effect and the Faraday+Coulomb effect, its flavor and centrality dependence may lead to the observed v 1 splittings. ...

... This is the so-called standard event plane method [13]. The event plane method has been widely used in the collective flow analysis in the past decades [14][15][16][17][18][19][20] , but it is still crucial to optimize the method for the CEE experiment and to validate that the collective flow signal obtained from CEE spectrometer is reliable. ...

... This simple model has proven to be very successful in describing the measured yields of many different hadron species in heavy-ion collisions across a broad collision energy range [22,27,[36][37][38]. Figure 1 depicts various F-O points from different experiments, including STAR-BES [27], NA49 [25,[39][40][41], E-802 [25,42,43], and GSI-SIS [44]. To fill the gap at high μ B , we additionally performed fits to the recent data for 0-10 % central Au-Au collisions at √ s NN = 3 GeV from the STAR Collaboration [45,46] using Thermal-FIST and the Id-HRG model in the strangeness-canonical ensemble. Namely, we fitted the 4π yields of primordial protons, light nuclei (d, 3 H, 3 H, 4 H), 054903-2 N part , and the yields of , K 0 S , K − , φ, − normalized by N part . ...

... However, most of the analytical work presented here will be useful for that case. Extending the study to a spin-1 target, such as the deuteron, would also be valuable since deuteron GPDs have very interesting new facets [52,53], and the DVCS and TCS processes on the deuteron should soon be experimentally accessible [54]. ...

... Moreover, subtle differences in background effects between Ru + Ru and Zr + Zr collisions arising from approximately defined nuclear structures can significantly influence the relative magnitudes of the CME observables. Furthermore, incorporating higher-order deformations, such as quadrupole β 2 and octupole β 3 deformations, into the WS equation could provide deeper insights into the event-by-event initial geometric configurations [39]. This would not only make the initial conditions more interesting but also lead to a more varied initial magnetic field, which could have significant implications for the observed CME signals. ...

The combined UrQMD+SMM framework has recently demonstrated its capabilities to describe the light nuclei and hypernuclei multiplicities and spectra in Au+Au collisions at √ s NN = 3 GeV [37] and is therefore well suited for the present analysis of harmonic flow.
