Baryogenesis in Models with a Low Quantum Gravity Scale
Karim Benakli, Sacha Davidson
We make generic remarks about baryogenesis in models where the scale of quantum gravity is much below the Planck scale. These correspond to M-theory vacua with a large volume…
Phenomenology of Low Quantum Gravity Scale Models
Karim Benakli
We study some phenomenological implications of models where the scale of quantum gravity effects lies much below the four-dimensional Planck scale. These models arise from M-theory…
Scales and Cosmological Applications of M Theory
Karim Benakli
I review recent results in three topics of the M-world: (i) Scales. (ii) New dark matter candidates. (iii) Cosmological solutions from p-branes. The three topics are discussed in t…
Heterotic String Theory on Anti-de-Sitter Spaces
Karim Benakli
We suggest that compactifications on Anti-de-Sitter (AdS) spaces of type IIA, IIB, heterotic strings and eleven dimensional vacuua of M-theory are related by a combination of a…
Cosmological Solution in M-theory on S^1/Z_2
Karim Benakli
We provide the first example of a cosmological solution of the Horava-Witten supergravity. This solution is obtained by exchanging the role of time with the radial coordinate of th…
Natural Candidates for Superheavy Dark Matter in String and M Theory
Karim Benakli, John Ellis, Dimitri V. Nanopoulos
We reconsider superheavy dark matter candidates in string and M theory, in view of the possibility that inflation might generate superheavy particles with an abundance close to tha…
