Inflation with a Growing Fifth Dimension
Rashmish K. Mishra, Michael Nee, Lisa Randall
Inflation generally assumes a field with nonzero potential that leads to inflationary expansion happening at arbitrarily early times. We demonstrate potentially observable conseque…
Testing F-theory GUTs with the Axiverse
Michael Nee, Mario Reig, Timo Weigand
We show that axions coupled to photons in F-theory Grand Unified Theories (GUTs) satisfy the coupling-to-mass relation $g_{aγ}/m_a \leq C\, \frac{α_{\rm em}}{2Ï}\frac{1}{m_Ïf_Ï…
Sequestered Conformal Anomaly Mediation (SCAM)
Michael Nee, Lisa Randall
Supersymmetric models in singular extra dimensional spaces feature prominently in many interesting phenomenological models, including those derived from string theory. In this pape…
More Effective RS Field Theory
Severin Lüst, Michael Nee, Lisa Randall
In this paper we derive the effective theory for a stabilized five-dimensional warped geometry, addressing several outstanding issues in this derivation. These include allowing for…
Warped Dimensions at the Cosmological Collider
Soubhik Kumar, Michael Nee
Extra dimensions are present in many beyond the Standard Model scenarios, most notably in string theory. However, direct signatures of extra dimensions are difficult to observe in…
