  3. Physics with CMS Forward Calorimeters Hadronic Forward (HF) CASTOR IP ZDC • Low-x dynamics: • Parton saturation, BFKL/CCFM dynamics, proton structure, multi-parton scattering • Diffraction • Measurements for cosmic ray data analysis: • Forward energy and particle flows, minimum bias event structure • Two-photon interactions and peripheral collisions • QED processes to determine luminosity to O(1%), via pp  pp ee and pp  pp  • Forward physics in pA and AA collisions • New forward physics phenomena: • Disoriented Chiral Condensates, incoherent pion emission, Centauros, Strangelets….

  4. Recent Developments • CASTOR approved by CMS-MB as CMS baseline detector on 21-05-07 • One calorimeter will be built by end of 2008 (224 channels) • FEA calculations completed • Prototype construction & assembly study completed • Skeleton construction studies completed • Full length octant prototype constructed and beam-tested in August, 2007 • EDR to be completed by end of October 2007 • CASTOR sim-digi software in HCAL CMSSW-1_7 release • 10.

  19. Summary • 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 !
