  The interaction between strong correlation and Berry curvature is an open
territory of in the field of quantum materials. Here we report large anomalous
Hall conductivity in a Kondo lattice ferromagnet USbTe which is dominated by
intrinsic Berry curvature at low temperatures. However, the Berry curvature
induced anomalous Hall effect does not follow the scaling relation derived from
Fermi liquid theory. The onset of the Berry curvature contribution coincides
with the Kondo coherent temperature. Combined with ARPES measurement and DMFT
calculations, this strongly indicates that Berry curvature is hosted by the
flat bands induced by Kondo hybridization at the Fermi level. Our results
demonstrate that the Kondo coherence of the flat bands has a dramatic influence
on the low temperature physical properties associated with the Berry curvature,
calling for new theories of scaling relations of anomalous Hall effect to
account for the interaction between strong correlation and Berry curvature.
