19 Summary  New Institutes are welcome !
Forward Physics spans a broad range of pp and HI high energy physics topics, from fundamental properties of QCD to new physics phenomena. Large cross sections ensure early publications on various topics. Discovery potential: - Beyond Standard Model (BSM): Large amount of missing transverse energy (MET) - Higgs: Vector-Boson-Fusion (VBF): Two jets at forward/backward rapidities (pp→jj H X). Lower background than the dominant gluon-gluon fusion channel (see David’s talk). - Exotics in HI Interactions: “Strangelets”, Disoriented-Chiral-Condensates (DCC) CASTOR calorimeter project is progressing fast: - Lots of data taken in test beam; Analysis under way. Engineering design review scheduled for the 31st October. Document in final stage. Construction of calorimeter to start in November 2007. Aim & need to be in beam line as soon as LHC starts, to take advantage of low lumi runs.  New Institutes are welcome !
