Declarative Reconfigurable Trust Management
William Marczak, David Zook, Wenchao Zhou +2
In recent years, there has been a proliferation of declarative logic-based trust management languages and systems proposed to ease the description, configuration, and enforcement o…
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…
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…
