Moduli stabilization and supersymmetry breaking in deflected mirage mediation

Abstract

We present a model of supersymmetry breaking in which the contributions from gravity/modulus, anomaly, and gauge mediation are all comparable. We term this scenario "deflected mirage mediation," which is a generalization of the KKLT-motivated mirage mediation scenario to include gauge mediated contributions. These contributions deflect the gaugino mass unification scale and alter the pattern of soft parameters at low energies. In some cases, this results in a gluino LSP and light stops; in other regions of parameter space, the LSP can be a well-tempered neutralino. We demonstrate explicitly that competitive gauge-mediated terms can naturally appear within phenomenological models based on the KKLT setup by addressing the stabilization of the gauge singlet field which is responsible for the masses of the messenger fields. For viable stabilization mechanisms, the relation between the gauge and anomaly contributions is identical in most cases to that of deflected anomaly mediation, despite the presence of the Kähler modulus. Turning to TeV scale phenomenology, we analyze the renormalization group evolution of the supersymmetry breaking terms and the resulting low energy mass spectra. The approach sets the stage for studies of such mixed scenarios of supersymmetry breaking at the LHC.

Study of dark matter physics in non-universal gaugino mass scenario

“…The phenomenology of the mirage mediation is discussed before the Higgs boson discovery in refs. [22][23][24][25][26][27][28][29][30][31][32][33] and after that in refs. [34][35][36][37][38][39][40].…”

Moduli-induced baryogenesis

“…Low energy values of the soft SUSY breaking parameters are determined by the renormalization group running, and extra gauge-charged matters if they exist at an intermediate scale [51][52][53][54].…”

The 126 GeV Higgs boson mass and naturalness in (deflected) mirage mediation

“…[28,29] where the gauge mediation also contributes comparably to the soft parameters as well as those from the other two mediation mechanisms. Such a generalized mediation mechanism can be constructed by adding the mediator field X and the messenger fields Ψ, Ψ as an usual gauge mediation scenario.…”

“…In this section, we review the most general framework of the mediation mechanism of supersymmetry breaking, that is, the deflected mirage mediation [28,29], based on a model shown in ref. [29].…”
