   * Yingxun will be here for 3 weeks, starting May 13
   * Our summer student is arriving around May 9
-  * Sergio
+  * Sergio is coming sometime in April
+====Group Business====
+  * Lab Move: floor is finished, then they will paint the walls (maybe?). Possibly moving next week.
+  * Efficiency (Jack): Two methods. A. Calculate fraction of the solid angle for each pixel. B. phi vs theta, times sin(theta)--integrate. Should equal A. For Method B to work, need enough bins in phi, theta and enough bins for each pixel
+  * Lee's Experiment: no update on the preamp box. Got remaining chip boards.
+  * HiRA Cans: ordering more screws. Jack will make sure Jimmy has the correct drawings.
+====Updates====
+  * Mike: E vs. Theta in lab and center of mass. No efficiency correction (yet). Theta/dOmega not smooth through theta
+  * Rachel: E vs Theta for 05049.  Multiplicity issues: the miniball multiplicity is from the TDC, did not work for first 3/4 of the experiment. So for now will use CsI multiplicity for cuts
+  * Zibi: study of varying theta(cm) cuts. Does not see a big dependence on width of Theta(cm) cut.
+  * Cuts on centrality: affects single-yields but not double ratio
+  * BUU: DR(n/p) always flat, DR(t/3He) increases with increasing energy (in calcium).
+===Spring Break next week: only Friday group meeting!===
