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…
Aligned Natural Inflation: Monodromies of two Axions
Rolf Kappl, Sven Krippendorf, Hans Peter Nilles
Natural (axionic) inflation can accommodate sizeable primordial tensor modes but suffers from the necessity of trans-Planckian variations of the inflaton field. This problem can be…
Rational F-Theory GUTs without exotics
Sven Krippendorf, Damian Kaloni Mayorga Pena, Paul-Konstantin Oehlmann +1
We construct F-theory GUT models without exotic matter, leading to the MSSM matter spectrum with potential singlet extensions. The interplay of engineering explicit geometric setup…
