SUMMARY:Naman Agarwal - Toward an Effective Theory of the Volume Modulus
DESCRIPTION:Speakers: Naman Agarwal (University of Manitoba)\n.\nAbstract: In this talk\, I will talk about my recent work with collaborators where we investigate the 4-dimensional effective theory of the warped volume modulus in the presence of stabilizing effects from gaugino condensation by analyzing the linearized 10-dimensional supergravity equations of motion. Warping is generally expected to scale down the masses of bulk modes to the IR scale at the tip of a throat. We find that the mass of the warped volume modulus evades expectations and is largely insensitive to the effects of warping\, even in strongly warped backgrounds. Instead\, the mass is parametrically tied to the 4-dimensional AdS curvature scale m2∼O(1)R^AdSm2∼O(1)R^AdS​\, presenting a challenge for scale separation in these backgrounds. We trace this effect to a universal contribution arising from the 10-dimensional equations of motion\, and comment on the importance of a 10-dimensional treatment of the warped volume modulus for effective field theories and model building.\nLink: Zoom\nAnLy: https://sites.google.com/view/anlystringsandfields\n \n \nhttps://indico.in2p3.fr/event/38783/
