New Constraints on the running-mass inflation model
Laura Covi, David H. Lyth, Alessandro Melchiorri
We evaluate new observational constraints on the two-parameter scale-dependent spectral index predicted by the running-mass inflation model by combining the latest Cosmic Microwave…
Bulk and brane anomalies in six dimensions
T. Asaka, W. Buchmüller, L. Covi
We study anomalies of six-dimensional gauge theories compactified on orbifolds. In addition to the known bulk anomalies, brane anomalies appear on orbifold fixpoints in the case of…
Effects of Squark Processes on the Axino CDM Abundance
Laura Covi, Leszek Roszkowski, Michael Small
We investigate the role of an effective dimension-4 axino-quark-squark coupling in the thermal processes producing stable cold axino relics in the early Universe. We find that, whi…
Exceptional Coset Spaces and Unification in Six Dimensions
T. Asaka, W. Buchmüller, L. Covi
The coset spaces E/SO(10)H allow complex structures which can account for three quark-lepton generations including right-handed neutrinos. We show that in the conte…
