DESCRIPTION:Speakers: Alba Reyes-Torrecilla\n\nWe utilize the universality
  of pion-pion ($\\pi\\pi$) final-state interactions at small invariant mas
 ses to understand the enhanced localized CP violation in $B^\\pm\\to K^\\p
 m\\pi^+\\pi^-$\, using a dispersive approach. From a fit to the integrated
  CP-asymmetry data\, we successfully predict the Dalitz-plot kinematic dis
 tribution of the asymmetry in the low-energy $\\pi\\pi$ region\, including
  the large localized CP violation recently observed by LHCb. An essential 
 role is played by the contributions of isospin 2. This formalism\, whose p
 arameters have a physical meaning\, can be adapted straightforwardly to ot
 her systems with CP violation enhanced by final-state interactions.\n\nhtt
