Flipped No-scale Supergravity: a Synopsis
J. Lopez, D. Nanopoulos
We discuss the highlights of recent developments in no-scale supergravity and flipped SU(5), especially in the context of a very light gravitino scenario that may explain the puzzl…
Flipped SU(5): a Grand Unified Superstring Theory (GUST) Prototype
J. Lopez, D. Nanopoulos
In this Lecture we first review the basic properties that make flipped SU(5) a very economical and well motivated unified model, including some recent developments regarding the pr…
A survey of phenomenological constraints on supergravity models
J. Lopez
We advocate the study of supergravity models as well motivated few-parameter low-energy supersymmetric models. In this context we survey a broad range of phenomenological constrain…
Tevatron energy and luminosity upgrades beyond the Main Injector
D. Amidei, A. Baden, G. Foster +6
The Fermilab Tevatron will be the world's highest energy hadron collider until the LHC is commissioned, it has the world's highest energy fixed target beams, and Fermilab will be t…
Theoretical expectations for the top-quark mass
J. Lopez
I review the theoretical expectactions for the top-quark mass in a variety of models: the Standard Model, unified models (GUTs), low-energy supersymmetric models (SUSY), unified su…
First Constraints on SU(5)xU(1) Supergravity from Trilepton Searches at the Tevatron
J. Lopez, D. Nanopoulos, G. Park +2
We present the first constraints on the parameter space of supergravity (in both no-scale and dilaton scenarios) which arise from the recently announced limits o…
