Sequestered de Sitter String Scenarios: Soft-terms
Luis Aparicio, Michele Cicoli, Sven Krippendorf +3
We analyse soft supersymmetry breaking in type IIB de Sitter string vacua after moduli stabilisation, focussing on models in which the Standard Model is sequestered from the supers…
Just enough inflation: power spectrum modifications at large scales
Michele Cicoli, Sean Downes, Bhaskar Dutta +2
We show that models of `just enough' inflation, where the slow-roll evolution lasted only e-foldings, feature modifications of the CMB power spectrum at large angular scale…
Inflating with Large Effective Fields
C. P. Burgess, M. Cicoli, F. Quevedo +1
We re-examine large scalar fields within effective field theory, in particular focussing on the issues raised by their use in inflationary models (as suggested by BICEP2 to obtain…
A 3.55 keV Photon Line and its Morphology from a 3.55 keV ALP Line
Michele Cicoli, Joseph P. Conlon, M. C. David Marsh +1
Galaxy clusters can efficiently convert axion-like particles (ALPs) to photons. We propose that the recently claimed detection of a 3.55--3.57 keV line in the stacked spectra of a…
Correlation between Dark Matter and Dark Radiation in String Compactifications
Rouzbeh Allahverdi, Michele Cicoli, Bhaskar Dutta +1
Reheating in string compactifications is generically driven by the decay of the lightest modulus which produces Standard Model particles, dark matter and light hidden sector degree…
N-flation with Hierarchically Light Axions in String Compactifications
Michele Cicoli, Koushik Dutta, Anshuman Maharana
We present an explicit embedding of axionic N-flation in type IIB string compactifications where most of the Kahler moduli are stabilised by perturbative effects, and so are hierar…
