Update on scalar singlet dark matter
James M. Cline, Kimmo Kainulainen, Pat Scott +1
One of the simplest models of dark matter is that where a scalar singlet field S comprises some or all of the dark matter, and interacts with the standard model through an HHSS cou…
Interacting dark matter contribution to the Galactic 511 keV gamma ray emission: constraining the morphology with INTEGRAL/SPI observations
Aaron C. Vincent, Pierrick Martin, James M. Cline
We compare the full-sky morphology of the 511 keV gamma ray excess measured by the INTEGRAL/SPI experiment to predictions of models based on dark matter (DM) scatterings that produ…
Fine-Tuning in Brane-antibrane Inflation
James M. Cline
I give a brief overview of brane-antibrane inflation, with emphasis on the problems of tuning to get a flat potential in the KKLMMT framework, and recent work on the nature of supe…
Overproduction of cosmic superstrings
Neil Barnaby, Aaron Berndsen, James M. Cline +1
We show that the naive application of the Kibble mechanism seriously underestimates the initial density of cosmic superstrings that can be formed during the annihilation of D-brane…
Warped Reheating in Brane-Antibrane Inflation
N. Barnaby, C. P. Burgess, J. M. Cline
We examine how reheating occurs after brane-antibrane inflation in warped geometries, such as those which have recently been considered for Type IIB string vacua. We adopt the stan…
Decoupling, Trans-Planckia and Inflation
C. P. Burgess, J. Cline, F. Lemieux +1
We survey recent calculations probing what constraints decoupling can put on the influence of very-high-energy physics on the predictions of inflation for the cosmic microwave back…
