Automorphic Structures of Heterotic Vacua
Jacob M. Leedom, Nicole Righi, Alexander Westphal
We study moduli stabilization in 4D effective field theories with Sp(4,) self-duality inspired by heterotic orbifold compactifications with Wilson lines. The target-spa…
Open Strings and Heterotic Instantons
Rafael Ãlvarez-GarcÃa, Christian KneiÃl, Jacob M. Leedom +1
Motivated by closed string perturbation theory arguments by S. Shenker, we consider non-perturbative effects of characteristic strength , with th…
Towards a Heterotic Axiverse
Jacob M. Leedom, Margherita Putti, Alexander Westphal
In this paper we initiate a broad study of some central properties of the string axiverse arising from Calabi-Yau compactifications of the perturbative heterotic th…
Dark Matter Nuclear Magnetic Resonance is Sensitive to Dark Photons and the Axion-Photon Coupling
Carl Beadle, Sebastian A. R. Ellis, Jacob M. Leedom +1
We demonstrate that nuclear magnetic resonance based searches for dark matter (DM) have intrinsic and powerful sensitivity to dark photons and the axion-photon coupling. The reason…
Exact Results in Chiral Gauge Theories with Flavor
Jacob M. Leedom, Hitoshi Murayama, Gup Singh +2
We present exact results in softly-broken supersymmetric chiral gauge theories with charged fermions in one antisymmetric, fundamental, and anti-…
Probing the UV with IR Axion Dark Matter Experiments
Jacob M. Leedom, Serah Moldovsky, Hitoshi Murayama
There is an ongoing and future experimental program searching for axions as both extensions of the Standard Model and as candidates for the observed dark matter. In this paper, we…
