Warped general gauge mediation

Abstract

We develop the formalism of "General gauge mediation" for five-dimensional theories in a slice of AdS space. A set of current correlators encodes the effect of a supersymmetry breaking hidden sector localised on the IR brane. These current correlators provide a tree-level gaugino mass and loop-level sfermion masses on the UV brane. We also use this formalism to calculate the Casimir energy and masses for bulk hyperscalars.To illustrate this general construction we consider a perturbative hidden sector of generalised messengers coupled to a spurion. For models with large warping, we find that when the AdS warp factor k is less than the characteristc mass scale M of the hidden sector, the whole Kaluza-Klein tower of vector superfields propagate supersymmetry breaking effects to the UV brane. When M is less than k, the zero modes dominate. † m.mcgarrie@qmul.ac.uk ‡ dthompson@tena4.vub.ac.be

Features of electroweak symmetry breaking in five dimensional SUSY models

“…Neutrino superfields may be included straightforwardly. [15][16][17][18][19]. The second model we wish to explore is outlined in table 2 and pictured in figure 1 (right).…”

“…where F and M are the free parameters we will scan over. This paper is the first implementation of five dimensional GMSB soft masses [16,17,[23][24][25], with five dimensional RGEs [5,6]. In both model 1 and 2 we will take the supersymmetry breaking to be on the opposite brane to the matter, and both brane and bulk matter are essentially suppressed by the effect of the extra dimension, as in the above equation.…”

“…In this model the 3rd generation is located on one brane and the 1st and 2nd generation on another, along with the supersymmetry breaking sector. The effects of supersymmetry breaking are mediated by gauge forces [26] (but one can also easily consider gravity mediation too in this context) and the result is that the 1st and 2nd generation and also the gauginos will receive normal (4D) GMSB soft mass contributions but the 3rd generation will be heavily suppressed [5,6,17,25]. The soft mass matrix for squarks and sleptons takes the form…”

“…A similar modification may be carried out with any publicly available spectrum generator [8-10] 1 . The RGEs used in this paper may be found in [5] and further conventions in [6] and [15][16][17][18][19]. For earlier phenomenological studies of five dimensional theories see for example [20].…”

Natural supersymmetry in warped space

“…To make progress, we consider the supersymmetric Randall-Sundrum model [22,[37][38][39][40][41][42][43][44][45] (cf. [46,47]).…”
