TL;DR
This paper investigates the quasinormal modes of various particles around unparticle-enhanced black holes, proposing these modes as potential signatures to distinguish ungravity effects from extra-dimensional theories.
Contribution
It provides the first detailed analysis of quasinormal modes in unparticle black hole backgrounds, highlighting their role as observational fingerprints for ungravity.
Findings
Quasinormal modes differ from those in extra-dimensional models.
Unitarity constraints restrict certain quasinormal modes in ungravity.
Unparticle effects mimic fractional extra dimensions in black hole geometry.
Abstract
In the background of unparticle-enhanced black hole geometry, we provide the quasinormal modes of scalar, vector, and Dirac particles around it. Ungravity by tensor unparticles contributes positively to the Newtonian gravity and black holes can be formed at the LHC without any extra dimensions. In the ungravity-dominant regime, the gravity looks much like that of the Schwarzschild geometry in fractional number of extra dimensions. We argue in this analysis that quasinormal modes are good fingerprints to distinguish ungravity from extra dimensions, by showing that the unitarity constraints on ungravity forbid some of the quasinormal modes which are allowed in extra dimensions.
