Swampland Program, Extra Dimensions, and Supersymmetry Breaking

Résumé

By combining swampland conjectures with observational data, it was recently suggested that the cosmo-logical hierarchy problem (i.e. the smallness of the dark energy in Planck units) could be understood asan asymptotic limit in field space, corresponding to a decompactification of one extra (dark) dimension ofa size in the micron range. In these Proceedings we examine the fundamental setting of this frameworkand discuss general aspects of the effective low energy theory inherited from properties of the overarchingstring theory. We then explore some novel phenomenology encompassing the dark dimension by look-ing at potential dark matter candidates, decoding neutrino masses, and digging into new cosmologicalphenomena.
