Stability of multibrane models
Marek Olechowski
Multibrane 5-dimensional models with a warped extra spatial dimension compactified on an orbifold are investigated. The Goldberger-Wise field, with appropriate b…
Axion clockworks from heterotic M-theory: the QCD-axion and its ultra-light companion
Sang Hui Im, Hans Peter Nilles, Marek Olechowski
A previously discussed clockwork mechanism within heterotic M-theory is applied to its axion landscape. We identify a unique candidate for a QCD-axion with a decay constant in the…
Heterotic M-Theory from the Clockwork Perspective
Sang Hui Im, Hans Peter Nilles, Marek Olechowski
Compactifications of heterotic M-theory are shown to provide solutions to the weak- and axion-scale hierarchy problems as a consequence of warped large extra dimensions. They allow…

Marcin Badziak, Marek Olechowski
Several models of inflation with the racetrack superpotential for the volume modulus coupled to a matter field are investigated. In particular, it is shown that two classes of race…

Dominika Konikowska, Marek Olechowski
Dilaton gravity with general brane localized interactions is investigated. Models with corrections up to arbitrary order in field derivatives are considered. Effective gravitationa…

Generalization of Einstein-Lovelock theory to higher order dilaton gravity
D. Konikowska, M. Olechowski
A higher order theory of dilaton gravity is constructed as a generalization of the Einstein-Lovelock theory of pure gravity. Its Lagrangian contains terms with higher powers of the…

Radion stabilization is analyzed in 5-dimensional models with branes in the presence of Gauss-Bonnet interactions. The Goldberger-Wise mechanism is considered for static and inflat…
Soft Supersymmetry Breaking in KKLT Flux Compactification
Kiwoon Choi, Adam Falkowski, Hans Peter Nilles +1
We examine the structure of soft supersymmetry breaking terms in KKLT models of flux compactification with low energy supersymmetry. Moduli are stabilized by fluxes and nonperturba…
Stability of flux compactifications and the pattern of supersymmetry breaking
K. Choi, A. Falkowski, H. P. Nilles +2
We extend the KKLT approach to moduli stabilization by including the dilaton and the complex structure moduli into the effective supergravity theory. Decoupling of the dilaton is n…
