Cosmological moduli problem ameliorated by decaying WIMPs
Howard Baer, Vernon Barger, Robert Wiley Deal
We investigate the cosmological moduli problem (CMP) in the context of supersymmetric models where discrete R-symmetries are used to suppress the mu term, and where mu is regenerat…
Global Asymptotics, the Swampland Conjectures, and Preheating of String Moduli
Leia Price, Kuver Sinha, Robert Wiley Deal
While the cosmological implications of the Swampland Conjectures are usually discussed in the context of inflationary model building, they also have implications for the violent, n…
Cosmological Moduli and Non-perturbative Production of Axions
Robert Wiley Deal, Leia Barrowes, John T. Giblin +3
Cosmological moduli generically come to dominate the energy density of the early universe, and thereby trigger an early matter dominated era. Such non-standard cosmological histori…
Multi-component Dark Matter and Small Scale Structure Formation
Robert Wiley Deal, Kishan Sankharva, Kuver Sinha +1
We consider the evolution of non-thermal dark matter perturbations in models which contain both Weakly Interacting Massive Particles (WIMPs) and axions. Using constraints from exis…
Dark matter and dark radiation from the early universe with a modulus coupled to the PQMSSM
Howard Baer, Vernon Barger, Robert Wiley Deal
The supersymmetrized DFSZ axion model is especially compelling in that it contains 1. the SUSY solution to the gauge hierarchy problem, 2. the Peccei-Quinn (PQ) solution to the str…
The Dark Universe after Reheating in String Inflation
Michele Cicoli, Kuver Sinha, Robert Wiley Deal
We study the production of dark matter and dark radiation after reheating in string inflation models where the Calabi-Yau has a fibred structure and the visible sector lives on D3…
On dark radiation from string moduli decay to ALPs
Howard Baer, Vernon Barger, Robert Wiley Deal
We examine the issue of dark radiation (DR) from string moduli decay into axion-like particles (ALPs). In KKLT-type models of moduli stabilization, the axionlike phases of moduli f…
The cosmological moduli problem and naturalness
Kyu Jung Bae, Howard Baer, Vernon Barger +1
The cosmological moduli problem (CMP) comes in three parts: 1. potential violation of BBN constraints from late decaying moduli fields, 2. the moduli-induced gravitino problem wher…
An anthropic solution to the cosmological moduli problem
Howard Baer, Vernon Barger, Robert Wiley Deal
Light moduli fields, gravitationally coupled scalar fields with no classical potential and which are expected to emerge as remnants from string theory compactification, are dangero…
Distribution of supersymmetry mu parameter and Peccei-Quinn scale f_a from the landscape
Howard Baer, Vernon Barger, Dibyashree Sengupta +1
A scan of soft SUSY breaking parameters within the string theory landscape with the MSSM assumed as the low energy effective field theory -- using a power-law draw to large soft te…
Is the magnitude of the Peccei-Quinn scale set by the landscape?
Howard Baer, Vernon Barger, Dibyashree Sengupta +3
Rather general considerations of the string theory landscape imply a mild statistical draw towards large soft SUSY breaking terms tempered by the requirement of proper electroweak…
