Greybody Factors and Charges in Kerr/CFT
Mirjam Cvetic, Finn Larsen
We compute greybody factors for near extreme Kerr black holes in D=4 and D=5. In D=4 we include four charges so that our solutions can be continuously deformed to the BPS limit. In…
Stability Walls in Heterotic Theories
Lara B. Anderson, James Gray, Andre Lukas +1
We study the sub-structure of the heterotic Kahler moduli space due to the presence of non-Abelian internal gauge fields from the perspective of the four-dimensional effective theo…
The B-L/Electroweak Hierarchy in Heterotic String and M-Theory
Michael Ambroso, Burt Ovrut
E8 x E8 heterotic string and M-theory, when compactified on a Calabi-Yau threefold admitting an SU(4) vector bundle with Wilson lines, can give rise to the exact MSSM spectrum with…
Two Higgs Pair Heterotic Vacua and Flavor-Changing Neutral Currents
Michael Ambroso, Volker Braun, Burt A. Ovrut
We present a vacuum of heterotic M-theory whose observable sector has the MSSM spectrum with the addition of one extra pair of Higgs-Higgs conjugate superfields. The quarks/leptons…
On the Initial Conditions in New Ekpyrotic Cosmology
Evgeny I. Buchbinder, Justin Khoury, Burt A. Ovrut
New Ekpyrotic Cosmology is an alternative scenario of early universe cosmology in which the universe existed before the big bang. The simplest model relies on two scalar fields, wh…
