We approach the following question: if supersymmetry is discovered, how can we select among different supersymmetric extensions of the Standard Model? In particular, we perform an analysis of the sparticle spectrum in low-energy string effective theories, asking which observables best distinguish various scenarios. We examine scenarios differing by the fundamental string scale and concentrate on GUT and intermediate scale models. We scan over four parameters (two goldstino angles, tan β and the… 

Required experimental accuracy to select between supersymmetrical models

We will present a method to decidea priori whether various supersymmetrical scenarios can be distinguished based on sparticle mass data alone. For each model, a scan over all free SUSY breaking

Theoretical uncertainties in sparticle mass predictions from computational tools

We estimate the current theoretical uncertainty in sparticle mass pre- dictions by comparing several state-of-the-art computations within the minimal su- persymmetric standard model (MSSM). We nd

Supersymmetry parameter analysis: SPA convention and project

Abstract.High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed

Requirements on collider data to match the precision of WMAP on supersymmetric dark matter.

If future colliders discover supersymmetric particles and probe their properties, one could predict the dark matter density of the Universe and would constrain cosmology with the help of precision

Phenomenology of twisted moduli in type-I string inspired models

We make a first study of the phenomenological implications of twisted moduli in type I intersecting D5-brane models, focussing on the resulting predictions at the LHC using SOFTSUSY to estimate the

Physics Beyond the Standard Model: Exotic Leptons and Black Holes at Future Colliders

The Standard Model of particle physics has been remarkably successful in describing present experimental results. However, it is assumed to be only a low-energy effective theory which will break down

Neutrinos in 5D SO(10) Unification

We study neutrino physics in a 5D supersymmetric SO(10) GUT. We analyze several different choices for realizing the See-Saw mechanism. We find that the "natural" scale for the Majorana mass of

Strings from Tachyons

We propose a new interpretation of the c=1 matrix model as the world-line theory of N unstable D-particles, in which the hermitian matrix is provided by the non- abelian open string tachyon. For



Measuring sparticle masses in non-universal string inspired models at the LHC

We demonstrate that some of the suggested five supergravity points for study at the LHC could be approximately derived from perturbative string theories or M-theory, but that charge and colour

Nonstandard string-SUSY scenario and its phenomenological implications

We investigate the phenomenology of an orbifold string model in which supersymmetry breaking is dominated by the overall {open_quotes}size{close_quotes} modulus field and all matter fields are in the

A Non-standard String/susy Scenario and Its Phenomenological Implications

We investigate the phenomenology of an orbifold string model in which supersymmetry breaking is dominated by the overalìsize' modulus eld and all matter elds are in the untwisted sector. The possibly

Theoretical uncertainties in sparticle mass predictions

We contrast the sparticle spectra obtained from three modern publicly available codes along model lines in minimal supersymmetric standard model (MSSM) parameter space. From this we gain an idea of

Initial Scales, Supersymmetric Dark Matter and Variations of Neutralino-Nucleon Cross Sections

The neutralino-nucleon cross section in the context of the MSSM with universal soft supersymmetry-breaking terms is compared with the limits from dark matter detectors. Our analysis is focussed on

Report of the SUGRA Working Group for run II of the Tevatron

Author(s): Barger, V; Wagner, CEM | Abstract: We present an analysis of the discovery reach for supersymmetric particles at the upgraded Tevatron collider, assuming that SUSY breaking results in

Impact of physical principles at very high energy scales on the superparticle mass spectrum

We survey a variety of proposals for new physics at high scales that serve to relate the multitude of soft supersymmetry breaking parameters of the MSSM. We focus on models where the new physics

Soft SUSY breaking, dilaton domination and intermediate scale string models

We present an analysis of the low-energy implications of an intermediate scale ( ~ 1011 GeV) string theory. We mainly focus on the evolution of the physical parameters under the renormalisation group
