CASTOR at CMS Enhancing Forward Physics Apostolos D. Panagiotou University of Athens http://cmsdoc.cern.ch/castor/ Diffractive & Forward Physics Workshop Antwerp 25-26/10, 2007 Slide 2 CMS Coverage in p T - CMS fwd calorimetry up to | | 5 + Castor + ZDC 0-12-10-8-6-4-2+2+4+6+8+10+12 p T (GeV) 0.1 1 10 100 1000 CMS T1 T2 RP p T max ~ s exp(-) CASTOR ZDC HF figure adapted from Risto Orava (Diffraction 2006) Unprecedented coverage at hadron colliders ! Slide 3 CASTOR ZDC Physics with CMS Forward Calorimeters Hadronic Forward (HF) 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. IP Slide 4 Recent Developments 1.CASTOR approved by CMS-MB as CMS baseline detector on 21-05-07 2.One calorimeter will be built by end of 2008 (224 channels) 3.FEA calculations completed 4.Prototype construction & assembly study completed 5.Skeleton construction studies completed 6.Full length octant prototype constructed and beam-tested in August, 2007 7.EDR to be completed by end of October 2007 8.CASTOR sim-digi software in HCAL CMSSW-1_7 release 10. Resources approaching required level for completion. Missing ~ 150 k New Institutes are Welcome ! Currently working on: - test beam data analysis, - electronics, construction - software ( implementation in simulation of digi & reco) - physics simulations, ..

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 Davids 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 31 st 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 !
