1. Some Thoughts and Pleas from the SCIPP (UC Santa Cruz) Group US ATLAS e  Forum Meeting June 27 2008 Bruce Schumm, UCSC/SCIPP, for Alan Litke, Jason Nielsen (faculty) Jovan Mitrevksi (Postdoc), Gabe Hare (Student)

2. Conversions of Non-Pointing Photons from GMSB Typical GMSB signatures: Neutralino/Stau decay length depends on coupling to gravitino…

3. Gauge-Mediated Supersymmetry Breaking Scenarios with in-flight decay not disfavored by cosmological constraints For a reasonable range of, e.g., gravitino mass, signature would be kinked track (possible with change in rate of ionization loss

4. For neutralino channel, signature is non- pointing photons and their converions. SCIPP: Explore conversion reconstruction for non-prompt, non-pointing photons. Pushes capabilities of TRTSeeded tracking Dataset identified that has non-prompt  (confirmed by Stephen Swedish, U. Alberta): misal1_mc12.005411.GMSB2_jimmy_susy.digit.RDO.v12000502_tid005449 Have reconstructed sample in 14.1.0 Hoped to make plots from InDetRecStat ntuple, but realized no neutrals retained  Need to learn to use AODs etc. (next step)

5. Others Jovan Mitrevski: Considering constributing to reconstruction of non-converting non-pointing photons (calibration issues) Alan Litke: Literature review; also deciding where to fit in. All in all, pretty vague, but hope to change that soon!
