A Note on Gaugino Masses in Kaluza-Klein/Radion Mediated SUSY Breaking | | Kaustubh Agashe

15 Dec 2000 | | Journal: | JHEP 0105 (2001) 017 | | Subject: | hep-ph | | Affiliation: | ITS, University of Oregon | | Abstract: | We review the equivalence of two approaches to study theories with gauge fields in extra spatial dimensions, namely the ``4D’’ approach (with KK states) and the ``5D’’ approach (with matching to the 4D theory at the compactification scale). In particular, we reiterate that there are two different power-law scalings of ``effective’’ gauge couplings. In a supersymmetric framework with SUSY breaking in the radius modulus, i.e., the field which fixes the size of the extra dimensions, these two approaches seem to give gaugino masses at loop-level (with a possible enhancement due to large number of Kaluza-Klein states) (hep-ph/0008069), and tree-level (hep-ph/0008103), respectively. We show explicitly how this discrepancy can be resolved. | | Source: | arXiv, hep-ph/0012182 | | Services: | Forum | Review | PDF | Favorites | |
