In contrast to the traditional femtoscopic analysis of identical pions, measurements with kaons can serve as a cleaner probe as they are less affected by resonance decays. Kaons contain strange quarks and have smaller cross section with hadronic matter than pions, so they may be sensitive to different effects and/or earlier collision stages.
Moreover, non-identical kaon femtoscopy can...
Azimuthally differential femtoscopic measurements, being sensitive to spatiotemporal characteristics of the source as well as collective velocity fields at freeze-out, provide very important information on the nature and dynamics of
the system evolution. While the radii modulations with respect to the second
harmonic event plane reflect mostly the spatial geometry of the source, the
third...
Azimuthally differential HBT is a powerful tool for investigating the source shape at freeze out.
In heavy ion collisions, the medium expansion through radial and anisotropic flow has been observed.
These hydrodynamic expansions result the deformation of the initial geometry.
Studying the deformation of the source shape by such strong expansion is the key to quantify the dynamics of the system...
Femtoscopic correlations between K$^0_{\rm S}$ and K$^{\rm \pm}$ are studied for the first time. Unlike the case of identical-kaon pairs which have correlations from quantum statistics and, if charged, the Coulomb interaction, K$^0_{\rm S}$K$^{\rm \pm}$ correlations can only take place through a strong final-state interaction. Analyses were performed on data from Pb-Pb collisions at...
In high-energy heavy-ion collisions, a hot and dense strongly
interacting system of deconfined quarks and gluons (sQGP) is created.
The Beam Energy Scan program at RHIC was performed to map the QCD phase
diagram. Femtoscopy allows one to measure the space-time extent of the
particle emitting source created in heavy-ion collisions. In this talk,
we present preliminary results of the measurement...
Through experiments with heavy-ion collisions at high energies we can study the properties of nuclear matter under extreme conditions. The information on the sizes of the particle-emitting sources can be inferred via the method of femtoscopy.
The femtoscopy method uses Quantum Statistics effects and the Final State Interactions to determine the space-time properties of the source. The radii...
Lambda-Kaon Femtoscopy in Pb-Pb Collisions at $\sqrt{s_{NN}}$ = 2.76 TeV with ALICE
We present results from a femtoscopic analysis of Lambda-Kaon correlations in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV by the ALICE experiment at the LHC. All pair combinations of $\Lambda$ and $\bar{\Lambda}$ with K$^{+}$, K$^{-}$ and K$^{0}_{S}$ are analyzed. The femtoscopic correlations are the...
THERMINATOR model is dedicated to heavy-ion collisions. Its current description allows one to work with data for the highest collision energies achieved by LHC and RHIC colliders. However it is possible to adapt THERMINATOR model to the lower energy spectrum as is used in Beam Energy Scan (BES) program at RHIC.
Femtoscopy of two particles investigates the properties of matter produced in...
