SUSY/SUGRA/String phenomenology

The unification of gauge coupling constants observed in the extrapolation of the high precision LEP data points to the general validity of the ideas of supersymmetry/supergravity and grand unification. This apparant success also then validates the underlying field theoretic approach at least up to the scaleMGUT ≈ 10 GeV. It is then entirely reasonable that one may extrapolate the grand unified ...

SUSY Phenomenology a

Supersymmetry (SUSY) is a symmetry between fermions and bosons and its theoretical development started from the formulation of SUSY invariant Lagrangian in four dimensional field theory in early ’70s. Subsequently, SUSY gauge theory, supergravity and string theory with space-time supersymmetry (supersrting) were formulated in ’70s. Phenomenological application of SUSY theory has developed since...

Radiative Corrections in Susy Phenomenology *

We discuss some aspects of the radiative corrections in the phenomenology of the minimal SUSY standard model, by reviewing two recent studies. (1) The full one-loop corrections to the Higgs boson decays into charginos are presented, with emphasis on the renormalization of the chargino sector, including of their mixing matrices. (2) The two-loopO(αs tanβ) corrections to the b → sγ decay in model...

Time and space dependent backgrounds from nonsupersymmetric strings

We investigate maximally symmetric backgrounds in nonsupersymmetric string vacua with D-branes and O-planes localized in the compact space. We find a class of solutions with a perturbative string coupling constant in all regions of spacetime. Depending on the particular model, we find either a time evolution with a big-bang type singularity or a space dependent background with generically orbif...

SUSY Phenomenology of KKLT Flux Compactifications

We study SUSY phenomenology of the KKLT (Kachru-Kallosh-Linde-Trivedi) scenario of string theory compactifications with fluxes. This setup leads to a specific pattern of soft masses and distinct phenomenological properties. In particular, it avoids the cosmological gravitino/moduli problems. Remarkably, the model allows for the correct abundance of SUSY dark matter consistently with all experim...
