Such a small mass gap is potentially a window into higher scale physics, as it may be sensitive to higher-dimensional operators. We show that still within AMSB one can get a much larger splitting in the Wino multiplet--a few GeV--if the scale of the new physics is comparable to the gravitino mass (which is indeed often the scale of new physics in anomaly mediation).18 pages; v2: references added, matching journal versionHigh Energy Physics - PhenomenologySplitting the Wino Multiplet by Higher-Dimensional Operators in Anomaly Mediationtext
