We analyze the semiclassical Horava-Lifshitz gravity for quantum scalar fields in 3+1 dimensions. We discuss the renormalization procedure based on adiabatic subtraction and dimensional regularization in the weak field approximation. We compute explicitly the second adiabatic order counterterms and the associated beta-functions in the minimal subtraction (MS) scheme. (Charla a cargo de Diana López Nacir)
