Summary of the analysis conducted during the May 14, 2010 meeting by T. Gogami. Replay of data for Chromium target with revision 415 while still undergoing analysis. Run ID ranges from 76956 to 77032 and 77098 to 77124, totaling 88 runs (approximately 1/4 of all runs) with an analysis time of 8 to 15 hours per run. Coincidence time calculations were performed with specific constraints. The Binding Region Missing Mass is under review with 1587 Λ observed over 46.1 hours and Coulomb interactions quantified at 1.31 C, resulting in 34 Λ per hour - consistent with previous findings. Activities include finalizing the analysis, reviewing coincidence times, providing data to the analyzer, and preparing a matrix using GEANT4.

52 Replay for Cr target with rev.415 still analyzing • replayed • Run ID : 76956 – 77032 • Run ID : 77098 – 77124 total 88 [runs] ( ~ 1/4 of all runs) • analysis time 8 – 15 [ hours/run ] ? coincidence time abs(htimetar – etimetar + 55)<1 coincidence time abs(htimetar – etimetar + 55 + 0.6)<1
Λ binding region Missing Mass ? • Number of Λ : 1587 • Time : 46.1 [h] • Coulomb : 1.31 [C] Λ 34 [/hour] same as before… (rev.256) Acc. Background
Sum and to do • Summary • replay for Cr target with rev.415 • Λ 34 [/hour] (same as before) • finished ! Gakushin • to do • check cointime • golden data to analyzer • matrix with GEANT4
