Abstract
We study the evolution of massive scalar field in the spacetime geometry of KehagiasSfetsos black hole in deformed HořavaLifshitz HL gravity by numerical analysis We find that the signature of HL theory is encoded in the quasinormal mode QNM phase of the evolution of field The QNM phase in the evolution process lasts for a longer time in HL theory QNMs involved in the evolution of massive field are calculated and find that they have a higher oscillation frequency and a lower damping rate than the Schwarzschild spacetime case We also study the relaxation of field in the intermediate and asymptotic range and verified that behaviors of field in these phases are independent of the HL parameter and is identical to the Schwarzschild case
