DESCRIPTION:We study the implications of extra dimensions of size $R\\sim 
 1/TeV$ on electroweak and flavor physics due to the presence of Kaluza-Kle
 in excitations of the SM gauge-bosons. We consider several scenarios with 
 the SM fermions either living in the bulk or being localized at different 
 points of an extra dimension. Global fits to electroweak observables provi
 de lower bounds on 1/R\, which are generically in the 2-5 TeV range. We fi
 nd\, however\, certain models where the fit to electroweak observables is 
 better than in the SM\, because of an improvement in the prediction to the
  weak charge Q_W. We also consider the case of softly-broken supersymmetri
 c theories and we find new non-decoupling effects that put new constraints
  on 1/R. If quarks of different families live in different points of the e
 xtra dimension\, we find that the Kaluza-Klein modes of the SM gluons gene
 rate (at tree level) dangerous flavor and CP-violating interactions. The l
 ower bound on 1/R can increase in this case up to 5000 TeV\, disfavoring t
 hese scenarios in the context of TeV-strings.\n\nhttps://indico.ific.uv.es
