Description
Experiments with high-energy heavy-ion collisions study properties of nuclear matter and its
transition from hadrons to a state of deconfined quarks and gluons,
the Quark-Gluon Plasma (QGP).
Femtoscopic measurements of two-particle correlations at small relative momenta
reveal the space-time characteristics of the system at
the moment of particle emission.
It has been predicted that correlations due to the strong final-state interactions (FSI) in a system with a narrow near-threshold resonance will be sensitive to the source size in the region of the resonance. Such a measurement can provide complementary information to the measurements at very low relative momenta. Since phi-meson ($\phi(1020)$) is a narrow resonance, it is ideal for the femtoscopic analysis of unlike-sign kaon pairs.
In this talk, we will present a status report of a STAR analysis of unlike-sign kaon femtoscopic correlations in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV. The experimental results will be compared to theoretical predictions that include the treatment of resonance formation due to final-state interactions.
