DESCRIPTION:We derive the general resummed effective Lagrangian for Higgs-
 mediated flavour-changing neutral-current (FCNC) interactions in the Minim
 al Supersymmetric Standard Model (MSSM)\, without resorting to particular 
 assumptions that rely on the squark-mass or the quark-Yukawa structure of 
 the theory. In our derivation we also include the possibility of explicit 
 CP violation through the Cabibbo--Kobayashi--Maskawa mixing matrix and sof
 t supersymmetry-breaking mass terms. The advantages of our resummed FCNC e
 ffective Lagrangian are explicitly demonstrated within the context of phen
 omenologically motivated scenarios. We obtain new testable predictions in 
 the large $\\tan\\beta$ regime of the theory for CP-conserving and CP-viol
 ating observables related to the $K$- and $B$-meson systems\, such as $\\D
 elta M_{K\,B}$\, $\\epsilon_K$\, $\\epsilon'/\\epsilon$\, ${\\cal B}(B_{d\
 ,s} \\to \\ell^+\\ell^-)$ and their associated leptonic CP asymmetries. Fi
 nally\, based on our resummed FCNC effective Lagrangian\, we can identify 
 configurations in the soft supersymmetry-breaking parameter space\, for wh
 ich a kind of a Glashow--Iliopoulos--Maiani-cancellation mechanism becomes
  operative and hence all Higgs-mediated\, tan(beta)-enhanced effects on K-
  and B-meson FCNC observables vanish.\n\nhttps://indico.ific.uv.es/event/1
