Localization and anomalies on orbifolds
S. Groot Nibbelink, H. P. Nilles
In this talk we discus some properties of supersymmetric theories on orbifolds in five dimensions. The structure of FI--tadpoles may lead to (strong) localization of charged bulk s…
Higgs mass sensitivity and localization due to Fayet-Iliopoulos terms on 5D orbifolds
S. Groot Nibbelink
In this talk we review calculations of FI-tadpoles in 5 dimensional (non-)supersymmetric orbifold theories. Some consequences of these tadpoles are discussed: quadratic Higgs-mass…
Kaluza-Klein towers on orbifolds: divergences and anomalies
S. Groot Nibbelink
The ultra-violet behavior of Kaluza-Klein theories on a one dimensional orbifold is discussed. An extension of dimensional regularization that can be applied to a compact dimension…
Inflationary perturbations with multiple scalar fields
B. J. W. van Tent, S. Groot Nibbelink
The calculation of scalar gravitational and matter perturbations during multiple-field inflation valid to first order in slow roll is discussed. These fields may be the coordinates…
Density perturbations arising from multiple field slow-roll inflation
S. Groot Nibbelink, B. J. W. van Tent
In this paper we analyze scalar gravitational perturbations on a Robertson-Walker background in the presence of multiple scalar fields that take values on a (geometrically non-triv…
