Comments on gluon 6-point scattering amplitudes in N=4 SYM at strong coupling
Dumitru Astefanesei, Suguru Dobashi, Katsushi Ito +1
We use the AdS/CFT prescription of Alday and Maldacena \cite{am} to analyze gluon 6-point scattering amplitudes at strong coupling in SYM. By cutting and gluing we obt…
Stationary black holes and attractor mechanism
Dumitru Astefanesei, Hossein Yavartanoo
We investigate the symmetries of the near horizon geometry of extremal stationary black holes in four dimensional Einstein gravity coupled to abelian gauge fields and neutral scala…
Moduli and (un)attractor black hole thermodynamics
Dumitru Astefanesei, Kevin Goldstein, Swapna Mahapatra
We investigate four-dimensional spherically symmetric black hole solutions in gravity theories with massless, neutral scalars non-minimally coupled to gauge fields. In the non-extr…
Note on counterterms in asymptotically flat spacetimes
Dumitru Astefanesei, Robert B. Mann, Cristian Stelea
We consider in more detail the covariant counterterm proposed by Mann and Marolf in asymptotically flat spacetimes. With an eye to specific practical computations using this counte…
Quasilocal Formalism and Black Ring Thermodynamics
Dumitru Astefanesei, Eugen Radu
The thermodynamical properties of a dipole black ring are derived using the quasilocal formalism. We find that the dipole charge appears in the first law in the same manner as a gl…
Nuttier Bubbles
Dumitru Astefanesei, Robert B. Mann, Cristian Stelea
We construct new explicit solutions of general relativity from double analytic continuations of Taub-NUT spacetimes. This generalizes previous studies of 4-dimensional nutty bubble…
