DESCRIPTION:Speakers: Patricia  Magalhaes (UCM)\n\nOne of the main open qu
 estions in particle physics is the observed mater-antimatter asymmetry in 
 our Universe. On the theoretical side\, the Standard Model can generate an
  asymmetry toward CP violation (CPV) mechanisms. However\, the amount know
 n is still not enough. From the experimental side\, this is one of the tar
 gets of LHCb collaboration\, the large hadron collider beauty facility at 
 CERN. CPV measurements are then\, widely recognized as a highly sensitive 
 probe of the Standard Model with new sources needed to account for the mat
 er-antimatter asymmetry observed in the Universe.\n\nThere is a long-term 
 discussion involving the source of the strong phase needed to generate dir
 ect CPV in charmless B and D decays. It could be new physics or due to non
 -perturbative hadronic contributions that are difficult to calculate from 
 first principles. In this talk\, I will present the main issues and ongoin
 g research on CP violation in heavy-meson hadronic decays. I will show tha
 tthe hadronic final state interactions can be a source of some observed as
 ymmetries in B → hhh (h = π\, K). I will also show in more detail a rec
 ent result where one can enhance the charge-parity (CP) violation differen
 ce between D0 → π−π+ and D0 → K−K+ decay up to the current exper
 imental value recently observed by the LHCb collaboration.\n\nhttps://indi
