1. Updates on JEF activities Somov, Jefferson Lab March 23, 2015 1

2. We decided to present JEF proposal to PAC next year - a lot of activities associated with the first beam in Hall D Major PAC request was to demonstrate the capability of taking data in parallel with GlueX - have to redo simulation for major channels using a hybrid calorimeter We are planning to do/finish the detector simulation during summer - fast sumulation and reconstruction (based on Island algorithm) of the PWO and lead glass calorimeter have already been implemented to GlueX geant (reasonably realistic simulation using Geant cluster shapes) - planning to implement detailed Geant simulatuion: preliminary PWO geant geometry has already been implemented Iliya Larin (ODU) is going to work on the algorithm integration 2

3. Simulation/Analyses status: Simon continues to work on the 3 gamma backround simulation Study p  0  0 background (alternative model), Sergei Gevorgyan Dipangkar Dutta started working with the GlueX simulation Dave is planning to study coincidential BG rates Study potential for B-boson searches, Liping JEF related activities Sean Tulin was invider to give a seminar at Jlab ``Searching for new light forces hidden in QCD`` JEF/GlueX presented at several meetings/conferences: QNP2015, MesonNet14, DNP,... 3
