Using a slave-boson approach, we demonstrate that the differential conductance and quasiparticle interference pattern measured in recent scanning tunneling spectroscopy experiments [Schmidt et al., Nature (London) 465, 570 (2010); Aynajian et al., Proc. Natl. Acad. Sci. USA 107, 10383 (2010)] in URu2Si2 are consistent with the emergence of a coherent Anderson lattice below the hidden order transition (HOT). Its formation is driven by a significant increase in the quasiparticle lifetime, which could arise from the emergence of a yet unknown order parameter at the HOT.
