Erratum (astro-ph/0510172): Robust Limits on Lorentz Violation from Gamma-Ray Bursts
John Ellis, N. E. Mavromatos, D. V. Nanopoulos +2
We correct the fitting formula used in refs. [1,2] to obtain a robust limit on a violation of Lorentz invariance that depends linearly on the photon energy. The correction leads to…
Realistic Type IIB Supersymmetric Minkowski Flux Vacua
Ching-Ming Chen, Tianjun Li, Yan Liu +1
We show that there exist supersymmetric Minkowski vacua on Type IIB toroidal orientifold with general flux compactifications where the RR tadpole cancellation conditions can be rel…
Realistic Yukawa Textures and SUSY Spectra from Intersecting Branes
Ching-Ming Chen, Tianjun Li, V. E. Mayes +1
We study the possible phenomenology of a three-family Pati-Salam model constructed from intersecting D6-branes in Type IIA string theory on the T^6/(Z2 x Z2) orientifold with some…
Supercriticality of a Class of Critical String Cosmological Solutions
Dimitri V. Nanopoulos, Dan Xie
For a class of Friedmann-Robertson-Walker type string solutions with compact hyperbolic spatial slices formulated in critical dimension, we find the world sheet conformal field the…
Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope
J. Albert et al., John Ellis, N. E. Mavromatos +3
We analyze the timing of photons observed by the MAGIC telescope during a flare of the active galactic nucleus Mkn 501 for a possible correlation with energy, as suggested by some…
No-Scale Solution to Little Hierarchy
Bhaskar Dutta, Yukihiro Mimura, Dimitri V. Nanopoulos
We show that the little hierarchy problem can be solved in the no-scale supergravity framework. In this model the supersymmetry breaking scale is generated when the electroweak sym…
Variations of the Hidden Sector in a Realistic Intersecting Brane Model
Ching-Ming Chen, Tianjun Li, V. E. Mayes +1
Recently, we discussed the first example of a phenomenologically realistic intersecting D6-brane model. In this model, the gauge symmetry in the hidden sector is USp(2)_1 x USp(2)_…
A Realistic World from Intersecting D6-Branes
Ching-Ming Chen, Tianjun Li, V. E. Mayes +1
We briefly describe a three-family intersecting D6-brane model in Type IIA theory on the T^6/(Z_2 x Z_2) orientifold with a realistic phenomenology. In this model, the gauge symmet…
