dc.description.abstract	We perform a Faddeev calculation for the three mesons system, ϕKK¯, taking the interaction between two pseudoscalar mesons and between a vector and a pseudoscalar meson from the chiral unitary approach which generates dynamically the low lying scalar mesons in the first case and the low lying axial vector mesons in the second. We obtain a neat resonance peak around a total mass of 2150 MeV and an invariant mass for the KK¯ system around 970 MeV, very close to the f0(980) mass. The state appears in I=0 and qualifies as a ϕf0(980) resonance. No state is seen in I=1. This finding provides a natural explanation for the recent state found at BABAR and BES, the X(2175), which decays into ϕf0(980).
