6 Jul 2005 | | Subject: | hep-th astro-ph gr-qc hep-ph | | Abstract: | dS/CFT gives a perturbatively gauge invariant definition of particle masses in de Sitter (dS) space. We show, in a toy model in which the graviton is replaced with a minimally coupled massless scalar field, that loop corrections to these masses are infrared (IR) divergent. We argue that this implies anomalous dependence of masses on the cosmological constant, in a true theory of quantum gravity. This is in accord with the hypothesis of Cosmological SUSY Breaking (CSB). | | Source: | arXiv, hep-th/0507055 | | Services: | Forum | Review | PDF | Favorites | |
