Algebraic Geometry in String Theory Seminar: Species Scale across String Moduli Spaces

Speaker:

Damian van de Heisteeg - CMSA

String theories feature a wide array of moduli spaces. We propose that the energy cutoff scale of these theories – the so-called species scale – can be determined through higher-curvature corrections. This species scale varies with the moduli; we use it both asymptotically to bound the diameter of the field space, as well as in the interior to determine a “desert point” where it is maximized.

Please note that there will be a pre-talk aimed at graduate students by David Wu from 10:00-10:30am
