  "abstract": "The feasibility of using $\\pi^{\\rm \\pm}$K$^0_{\\rm S}$ femtoscopy to experimentally study the K$^*_0(700)$ resonance is considered. The K$^*_0(700)$ resonance is challenging to study due to its broad width and proximity in mass to the K$^*(892)$, both of which predominantly decay via the $\\pi$K channel. One of the main interests in the K$^*_0(700)$ is that it is considered a candidate for a tetraquark state. It is proposed to use two-particle femtoscopic methods with $\\pi^{\\rm \\pm}$K$^0_{\\rm S}$ pairs produced in proton-proton and heavy ion collisions assuming a strong final-state interaction between them due to elastic scattering and/or via the K$^*_0(700)$ resonance. Calculations of $\\pi^{\\rm \\pm}$K$^0_{\\rm S}$ correlation functions are made to estimate the strength of these final-state interactions and to see if this signal can be adequately separated from the K$^*(892)$ background. A possible signature of diquark versus tetraquark behavior of the K$^*_0(700)$ final-state interaction is also discussed.",
