Effective Supergravity from 4-d Fermionic Strings
Kajia Yuan
The untwisted moduli in four-dimensional fermionic string models are identified by considering world-sheet Abelian Thirring interactions. The full Kahler potentials of untwisted se…
Number of Generations in Free Fermionic String Models,
Ioannis Giannakis, D. V. Nanopoulos, Kajia Yuan
In string theory there seems to be an intimate connection between spacetime and world-sheet physics. Following this line of thought we investigate the family problem in a particula…
Moduli and Kähler potential in fermionic strings
Jorge L. Lopez, D. V. Nanopoulos, Kajia Yuan
We study the problem of identifying the moduli fields in fermionic four-dimensional string models. We deform a free-fermionic model by introducing exactly marginal operators in the…
Scrutinizing Supergravity Models through Neutrino Telescopes
Raj Gandhi, Jorge L. Lopez, D. V. Nanopoulos +2
Galactic halo neutralinos () captured by the Sun or Earth produce high-energy neutrinos as end-products of various annihilation modes. These neutrinos can travel from the Sun or…
Aspects of Neutralino Dark Matter
Kajia Yuan
The possible solution of dark matter problem with neutralinos of supersymmetric models within the supergravity framework is reviewed. A novel correlation between the neutralino rel…
Precision Electroweak Tests of the Minimal and Flipped SU(5) Supergravity Models
J. Lopez, D. V. Nanopoulos, G. Park +2
We explore the one-loop electroweak radiative corrections in the minimal and the no-scale flipped supergravity models via explicit calculation of vacuum polarizatio…
