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…
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…
