The cosmological constant is probably still zero
Yang Liu, Antonio Padilla, Francisco G. Pedro
We consider a wide class of four-dimensional effective field theories in which gravity is coupled to multiple four-forms and their dual scalar fields, with membrane sources charged…
Early Dark Energy in Type IIB String Theory
Michele Cicoli, Matteo Licheri, Ratul Mahanta +3
Early Dark Energy (EDE) is a promising model to resolve the Hubble Tension, that, informed by Cosmic Microwave Background data, features a generalization of the potential energy us…
Stringy multifield quintessence and the Swampland
Max Brinkmann, Michele Cicoli, Giuseppe Dibitetto +1
We consider quintessence models within 4D effective descriptions of gravity coupled to two scalar fields. These theories are known to give rise to viable models of late-time cosmic…
Secondary GWs and PBHs in string inflation: formation and detectability
Michele Cicoli, Francisco G. Pedro, Nicola Pedron
We derive the spectrum and analyse the detectability prospects of secondary gravity waves (GWs) associated to primordial black hole (PBH) production in a class of string inflationa…
Environmental selection of the cosmological constant and electroweak scales
Matteo Moretti, Francisco Gil Pedro
We investigate whether selfish/Goldilocks Higgs models can be extended to accomodate vacua with both the right Higgs mass and cosmological constant. Through the introduction of mul…
Quintessence and the Swampland: The numerically controlled regime of moduli space
Michele Cicoli, Francesc Cunillera, Antonio Padilla +1
We provide a detailed discussion of the main theoretical and phenomenological challenges of quintessence model building in any numerically controlled regime of the moduli space of…
