Query: Studies of final state interactions via femtoscopy in ALICE   Femtoscopy is a technique enabling measurements of the space-time
characteristics of particle-emitting sources. However, the femtoscopic analysis
is also sensitive to the interaction cross-section. In this paper we show the
first preliminary measurements of $\rm K^0_SK^{\pm}$ correlation functions in
Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV. These correlations originate
from the final-state interactions which proceed through the $a_0(980)$
resonance only and can be employed to constrain its parameters. A similar
approach can be applied to baryon pairs to extract the unknown interaction
cross-sections for some (anti-)baryon-(anti-)baryon pairs. We show
baryon--baryon and baryon--anti-baryon correlation functions of protons and
lambdas, as well as discuss shortly the fitting method.
