Stringy N = 1 super no-scale models
Costas Kounnas, Herve Partouche
N=1 no-scale models describe at tree level the spontaneous breaking of supersymmetry at an arbitrary scale m_{3/2}, with vanishing vacuum energy. We define N=1 super no-scale model…
Aspects of Quadratic Gravity
Luis Alvarez-Gaume, Alex Kehagias, Costas Kounnas +2
We discuss quadratic gravity where terms quadratic in the curvature tensor are included in the action. After reviewing the corresponding field equations, we analyze in detail the p…
Black Hole Solutions in Gravity
Alex Kehagias, Costas Kounnas, Dieter Lust +1
We find static spherically symmetric solutions of scale invariant gravity. The latter has been shown to be equivalent to General Relativity with a positive cosmological const…
