Global Embedding of Fibre Inflation Models
Michele Cicoli, Francesco Muia, Pramod Shukla
We present concrete embeddings of fibre inflation models in globally consistent type IIB Calabi-Yau orientifolds with closed string moduli stabilisation. After performing a systema…
Light Higgsino Dark Matter from Non-thermal Cosmology
Luis Aparicio, Michele Cicoli, Bhaskar Dutta +2
We study the scenario of higgsino dark matter in the context of a non-standard cosmology with a period of matter-domination prior to Big-Bang nucleosynthesis. Matter-domination cha…
Moduli Vacuum Misalignment and Precise Predictions in String Inflation
Michele Cicoli, Koushik Dutta, Anshuman Maharana +1
The predictions for all the cosmological observables of any inflationary model depend on the number of e-foldings which is sensitive to the post-inflationary history of the univers…
Affleck-Dine Baryogenesis in Type IIB String Models
Rouzbeh Allahverdi, Michele Cicoli, Francesco Muia
We present a viable string embedding of Affleck-Dine baryogenesis in type IIB sequestered models where the late-time decay of the lightest modulus reheats the universe to relativel…
Recent developments in string model-building and cosmology
Michele Cicoli
In this talk I discuss recent developments in moduli stabilisation, SUSY breaking and chiral D-brane models together with several interesting features of cosmological models built…
Robust Inflation from Fibrous Strings
C. P. Burgess, M. Cicoli, S. de Alwis +1
Successful inflationary models should (i) describe the data well; (ii) arise generically from sensible UV completions; (iii) be insensitive to detailed fine-tunings of parameters a…
