DESCRIPTION:In my talk\, I will present a data-driven coupled-channel anal
 ysis of the isoscalar S-wave $\\pi\\pi/KK$ scattering using partial-wave d
 ispersion relations. The central result is the Omnes matrix\, which has on
 ly right-hand cuts\, making it a crucial input for studying the final stat
 e interactions of any hadron processes involving a system of two pions (an
 d two kaons). As an application\, I will showcase our recent findings on $
 ee \\to J/\\psi\\pi\\pi(KK)$ and $\\gamma*\\gamma* \\to \\pi\\pi/KK$ sca
 ttering. The results from $\\gamma*\\gamma* \\to \\pi\\pi/KK$ allowed us t
 o perform a dispersive estimation of the contributions of the $f_0(500)$ a
 nd $f_0(980)$ resonances to $(g-2)_\\mu$.\n\nhttps://indico.ific.uv.es/eve
