Supersymmetry dileptons and trileptons at the Tevatron
J. Lopez, D. Nanopoulos, X. Wang +1
We consider the production of supersymmetry neutralinos and charginos in collisions at the Tevatron, and their subsequent decay via hadronically quiet dileptons and trile…
Direct detection of dark matter in SU(5)xU(1) supergravity
X. Wang, J. Lopez, D. Nanopoulos
We compute the scattering rates for the lightest neutralino in the forthcoming germanium detector and a proposed lead detector $(^{207}{\rm…
String no-scale supergravity
J. Lopez, D. Nanopoulos
We explore the postulates of string no-scale supergravity in the context of free-fermionic string models. The requirements of vanishing vacuum energy, flat directions of the scalar…
New phenomena in the standard no-scale supergravity model
S. Kelley, J. Lopez, D. Nanopoulos +1
We revisit the no-scale mechanism in the context of the simplest no-scale supergravity extension of the Standard Model. This model has the usual five-dimensional parameter space pl…
Experimental consequences of one-parameter no-scale supergravity models
J. Lopez, D. Nanopoulos, A. Zichichi
We consider the experimental predictions of two {\em one-parameter} no-scale supergravity models with string-inspired moduli and dilaton seeds of supersymmetry b…
New constraints on supergravity models from
J. Lopez, D. Nanopoulos, X. Wang +1
We perform a detailed study of the constraints from on a large class of supergravity models, including generic four-parameter supergravity models, the minimal sup…
A light stop and its consequences at the Tevatron and LEPII
J. Lopez, D. Nanopoulos, A. Zichichi
An interesting prediction of a string-inspired {\em one-parameter} supergravity model, is the fact that the lightest member () of the top-squark doub…
Precision Electroweak Tests on the Model
T. K. Kuo, Gye T. Park
We perform precision electroweak tests on the model. The purpose of the analysis is to delineate the model parameters such as the mixing angles of the extra…
Status of the superworld: from theory to experiment
J. Lopez, D. Nanopoulos, A. Zichichi
Review to appear in Progress in Particle and Nuclear Physics. Contents: {1}Introduction}{1} {2}High precision LEP data and convergence of couplings: physics is not Euclidean geomet…
Closing the Universe by relaxing the cosmological constant
J. Lopez, D. Nanopoulos
We propose a string-inspired model which correlates several aspects of particle physics and cosmology. Inspired by the flat directions and the absence of adjoint Higgs representati…
The top-quark mass in SU(5)xU(1) supergravity
J. Lopez, D. Nanopoulos, A. Zichichi
We show that the currently experimentally preferred values of the top-quark mass (\ie, $130\lsim m_t\lsim180\GeV$) are naturally understood in the context of string models, where t…
Two-Loop Neutrino Masses and the Solar Neutrino Problem
Debajyoti Choudhury, Raj Gandhi, J. A. Gracey +1
The addition of singlet right-handed neutrinos to the Standard Model leads to radiatively generated mass corrections for the doublet neutrinos. For those neutrinos w…
Experimental aspects of SU(5)xU(1) supergravity
J. Lopez, D. Nanopoulos, G. Park +2
We study various aspects of supergravity as they relate to the experimental verification or falsification of this model. We consider two string-inspired, univers…
