Anisotropic Null String Cosmologies
Ioannis Giannakis, K. Kleidis, K. Kuiroukidis +1
We study string propagation in an anisotropic, cosmological background. We solve the equations of motion and the constraints by performing a perturbative expansion of the string co…
Massive Higher Spin States in String Theory and the Principle of Equivalence
Ioannis Giannakis, James T. Liu, Massimo Porrati
In this paper we study three point functions of the Type II superstring involving one graviton and two massive states, focusing in particular on the spin-7/2 fermions at the first…
Supersymmetric Sum Rules for Electromagnetic Multipoles
Ioannis Giannakis, James T. Liu, Massimo Porrati
We derive model independent, non-perturbative supersymmetric sum rules for the magnetic and electric multipole moments of any theory with N=1 supersymmetry. We find that in any irr…
