Realistic Four-Generation MSSM in Type II String Theory
A. V. Belitsky, Richard F. Lebed, Van E. Mayes
We construct a four-generation MSSM with rank-4 Yukawa matrices from intersecting D6 branes on a T^6/(Z_2 x Z_2) orientifold. The Yukawa matrices obtained provide an example of Fla…
Baryon Magnetic Moments in Alternate 1/N_c Expansions
Richard F. Lebed, Russell H. TerBeek
Recent work shows not only the necessity of a 1/N_c expansion to explain the observed mass spectrum of the lightest baryons, but also that at least two distinct large N_c expansion…
Tribimaximal Neutrino Mixing from A_4 Replication
Christopher D. Carone, Richard F. Lebed
Motivated by dimensional deconstruction, we propose a model of tribimaximal neutrino mixing based on A_4 x A_4 symmetry. In this model, the two triplet symmetry-breaking fields of…
Knotting and higher order linking in physical systems
Roman V. Buniy, Martha J. Holmes, Thomas W. Kephart
We discuss physical systems with topologies more complicated than simple gaussian linking. Our examples of these higher topologies are in non-relativistic quantum mechanics and in…
Neutrinos, WMAP, and BBN
Lawrence M. Krauss, Cecilia Lunardini, Christel Smith
New data from WMAP have appeared, related to both the fractional energy density in relativistic species at decoupling and also the primordial helium abundance, at the same time as…
Chiral asymmetry and axial anomaly in magnetized relativistic matter
E. V. Gorbar, V. A. Miransky, I. A. Shovkovy
The induced axial current and the chiral anomaly are studied in the normal phase of magnetized relativistic matter. A special attention is paid to the role of the chiral shift para…
