Relaxion Monodromy and the Weak Gravity Conjecture
Luis E. Ibanez, Miguel Montero, Angel Uranga +1
The recently proposed relaxion models require extremely large trans-Planckian axion excursions as well as a potential explicitly violating the axion shift symmetry. The latter prop…
Minkowski 3-forms, Flux String Vacua, Axion Stability and Naturalness
Sjoerd Bielleman, Luis E. Ibanez, Irene Valenzuela
We discuss the role of Minkowski 3-forms in flux string vacua. In these vacua all internal closed string fluxes are in one to one correspondence with quantized Minkowski 4-forms. B…
Multifield Dynamics in Higgs-otic Inflation
S. Bielleman, L. E. Ibanez, F. G. Pedro +1
In Higgs-otic inflation a complex neutral scalar combination of the and MSSM Higgs fields plays the role of inflaton in a chaotic fashion. The potential is protected fr…
Transplanckian axions !?
Miguel Montero, Angel M. Uranga, Irene Valenzuela
We discuss quantum gravitational effects in Einstein theory coupled to periodic axion scalars to analyze the viability of several proposals to achieve superplanckian axion periods…
