We show that in a specific class of models, known as semi-direct gauge mediation, it is possible to avoid gaugino screening by allowing for a chiral messenger sector. Messengers then acquire a mass at some scale, for instance by higgsing or by some auxiliary strong coupling dynamics. We implement this idea in a simple model which we work out explicitly.", "revisions": [ { "version": "v2", "updated": "2010-12-06T09:32:47.000Z" } ], "analyses": { "keywords": [ "gaugino mass", "auxiliary strong coupling dynamics", "gauge mediation models", "chiral messenger sector", "semi-direct gauge mediation" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer", "journal": "Journal of High Energy Physics", "year": 2010, "month": "Dec", "volume": 2010, "pages": 64 }, "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "inspire": 859846, "adsabs": "2010JHEP...12..064A" } } }
