Introduction

The bfcMixer/embedding chain only embeds TPC and FTPC data currently. We are trying to integrate EEMC embedding to it. (Note: EEMC only! BEMC is not involved yet) A first version of the embedding program is finished (Thanks to Jan and Eric of PDSF) It reads data of daq files and MC of fzd files and outputs embeded data to root files. Embedded data are passed using StEmcCollection from StEEmcMixerMaker to StEmcRawMaker instead of StTables as FTPC embedding. StEEmcMixerMaker which is responsible for embedding is modifed from the exsisting EEMC standalone embedding maker and its I/O is totally changed. StEEmcSlowMaker is the default simulator now instead of StEEmcFastMaker. A flow chart of the modfied StEEmcMixerMaker and the bfcMixer is plotted in Fig. 1. (Power Point files of Figs. for a clearer view can be found in appendix)

The official StEmcRawMaker which generates StEmcCollection from daq for the data production chain is modifed to allow embedding. Its flow chart is plotted in Fig. 2.

More tests are on the way

Tests by EEMC software group (Jan, Weihong ......)

Tests with synchronized data (Andrew Rose of PDSF promised to generate for us)

What's next

Acceptance of EEMC pion with single MC pions

Association maker interfaced with StEEmcCluster/Point makers

Peer review

Acceptance of EEMC pion with MC events

MC study on EEMC gamma, mesons: Kshort and rho, baryons

Extension to BEMC?
