The Gamma-Ray Spectrum<br />
Heavier gravitino: m 3/2 > m W , m Z<br />
ψ 3/2 → Z 0 ν<br />
ψ 3/2 → W ± l ∓<br />
ψ 3/2 → hν<br />
are kinematically allowed<br />
Only two free parameters: m 3/2 , τ 3/2 (under assumption of gaugino<br />
mass universality at the GUT scale, neglecting Higgs channel)<br />
