Lifetime of flying particles in canonical Doubly Special Relativity

S. Mignemi

We discuss the corrections to the lifetime of unstable elementary particles in some models of doubly special relativity. We assume that the speed of light is invariant and that the…

Extended uncertainty principle and the geometry of (anti)-de Sitter space

S. Mignemi

It has been proposed that on (anti)-de Sitter background, the Heisenberg uncertainty principle should be modified by the introduction of a term proportional to the cosmological con…

Gravitational wave signatures of the absence of an event horizon. I. Nonradial oscillations of a thin-shell gravastar

Paolo Pani, Emanuele Berti, Vitor Cardoso +2

Gravitational waves from compact objects provide information about their structure, probing deep into strong-gravity regions. Here we illustrate how the presence or absence of an e…

BPS-like bound and thermodynamics of the charged BTZ black hole

M. Cadoni, C. Monni

The charged Banados-Teitelboim-Zanelli (BTZ) black hole is plagued by several pathologies: a) Presence of divergent boundary terms in the action, hence of a divergent black hole ma…

Are black holes in alternative theories serious astrophysical candidates? The case for Einstein-Dilaton-Gauss-Bonnet black holes

Paolo Pani, Vitor Cardoso

It is generally accepted that Einstein's theory will get some as yet unknown corrections, possibly large in the strong field regime. An ideal place to look for these modifications…

General models of Einstein gravity with a non-Newtonian weak-field limit

M. Cadoni, M. Casula

We investigate Einstein theories of gravity, coupled to a scalar field \vphi and point-like matter, which are characterized by a scalar field-dependent matter coupling function e^{…
