Charged black holes in the 1/N expansion
Georges Obied, Mario Reig
We study some implications of theories coupled to gravity in the large- limit. We find that in theories with quarks transforming as , bl…
Testing the Heterotic String with the Axion-Photon Coupling
Mario Reig, Timo Weigand
The discovery of an axion-like particle above the QCD line would rule out Grand Unified Theories, including the perturbative heterotic string with the Standard Model embedded in a…
String Theory and Grand Unification Suggest a Sub-Microelectronvolt QCD Axion
Joshua N. Benabou, Katherine Fraser, Mario Reig +1
Axions, grand unification, and string theory are each compelling extensions of the Standard Model. We show that combining these frameworks imposes strong constraints on the QCD axi…
Exploring the Dark Universe: A European Strategy for Axions and other WISPs Discovery
Deniz Aybas, Francesca Calore, Michele Cicoli +17
Axions and other very weakly interacting slim (with 1 GeV) particles (WISPs) are a common feature of several extensions of the Standard Model of Particle Physics. The search…
