Axionic Mirage Mediation
Although the mirage mediation is one of the most plausible mediation mechanisms of supersymmetry breaking, it suffers from two crucial problems. One is the μ-/Bμ-problem and the second is the cosmological one. The former stems from the fact that the B parameter tends to be comparable with the gravitino mass, which is two order of magnitude larger than the other soft masses. The latter problem i...
متن کاملProspects for Mirage Mediation
Mirage mediation reduces the fine-tuning in the minimal supersymmetric standard model by dynamically arranging a cancellation between anomaly-mediated and modulus-mediated supersymmetry breaking. We explore the conditions under which a mirage “messenger scale” is generated near the weak scale and the little hierarchy problem is solved. We do this by explicitly including the dynamics of the SUSY...
متن کاملLHC Signature of Mirage Mediation
We study LHC phenomenology of mirage mediation scenario in which anomaly and modulus contributions to soft SUSY breaking terms are comparable to each other. A Monte Carlo study of mirage mediation, with model parameters α = 1, M 0 = 500 GeV, n M = 1/2, n H = 1 and tanβ = 10, is presented. It is shown that masses of supersymmetric particles can be measured in a model independent way, providing i...
متن کاملDark Matter Prospects in Deflected Mirage Mediation
The recently introduced deflected mirage mediation (DMM) model is a string-motivated paradigm in which all three of the major supersymmetry-breaking transmission mechanisms are operative. We begin a systematic exploration of the parameter space of this rich model context, paying special attention to the pattern of gaugino masses which arise. In this work we focus on the dark matter phenomenolog...
متن کاملDark matter signals in deflected mirage mediation
We investigate the parameter space of a specific class of model within the deflected mirage mediation (DMM) scenario. We look at neutralino properties and compute the thermal relic density as well as interaction rates with xenon direct detection experiments. We find that there are portions of the parameter space which are in line with the current WMAP constraints. Further we find that none of t...
