Combining Supersymmetric Dark Matter with Recent Accelerator Data
A. B. Lahanas, D. V. Nanopoulos, V. C. Spanos
In the framework of the Constrained Minimal Supersymmetric Standard Model we discuss the impact of the recent experimental information, especially from the E821 Brookhaven experime…
Lower Limits on Soft Supersymmetry-Breaking Scalar Masses
John Ellis, D. V. Nanopoulos, Keith A. Olive
Working in the context of the CMSSM, we argue that phenomenological constraints now require the universal soft supersymmetry-breaking scalar mass m_0 be non-zero at the input GUT s…
Non-Critical Liouville String Escapes Constraints on Generic Models of Quantum Gravity
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
It has recently been pointed out that generic models of quantum gravity must contend with severe phenomenological constraints imposed by gravitational Cerenkov radiation, neutrino…
Dark Matter Direct Searches and the Anomalous Magnetic Moment of Muon
A. B. Lahanas, D. V. Nanopoulos, V. C. Spanos
In the framework of the Constrained Minimal Supersymmetric Standard Model (CMSSM) we discuss the impact of the recent experimental information, especially from E821 Brookhaven expe…
$tring Theory and an Accelerating Universe
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
An accelerating Universe can be accommodated naturally within non-critical string theory, in which scattering is described by a superscattering matrix $ that does not factorize as…
Phenomenology of Non-Abelian Flat Directions in a Minimal Superstring Standard Model
G. B. Cleaver, A. E. Faraggi, D. V. Nanopoulos +1
Recently, we presented the first non-Abelian flat directions that produce from a heterotic string model solely the three-generation MSSM states as the massless spectrum in the obse…
Inflationary Baryogenesis
D. V. Nanopoulos, Raghavan Rangarajan
In this letter we explore the possibility of creating the baryon asymmetry of the universe during inflation and reheating due to the decay of a field associated with the inflaton.…
Combining the Muon Anomalous Magnetic Moment with other Constraints on the CMSSM
J. Ellis, D. V. Nanopoulos, K. A. Olive
We combine the constraint suggested by the recent BNL E821 measurement of the anomalous magnetic moment of the muon on the parameter space of the constrained MSSM (CMSSM) with thos…
