Measurement of the H-> WW* decay at 3 TeV CLIC

  • Speaker: Mila Pandurovic (University of Belgrade (RS))
  • Status: accepted/merged with ILD H-> WW* talk
  • Proposed time: 25 min
  • Abstract: The study presented in this talk is part of an effort to investigate the complete physics potential of a CLIC collider operated at various energies for measurements of the SM Higgs boson properties. In this talk, the physics potential for the measurement of the Higgs production cross section in WW fusion times the branching ratio for the H -> WW* decay at the highest energy stage of CLIC operation, 3 TeV, is presented. The analysis is performed in a full simulation including pile-up from gamma gamma -> hadrons and all relevant physics background channels.

Reconstruction of boosted top quarks at high-energy CLIC

  • Speaker: Rickard Stroem (CERN)
  • Status: Accepted
  • Time: 15+5min
  • Abstract: In this talk we will discuss the reconstruction of e+e- -> tt events at the two higher energy stages of the CLIC programme with collision energies of 1.5 and 3 TeV respectively. Ongoing studies are based on full detector simulations including pile-up from beam-induced backgrounds. The potential of techniques originally developed for hadron colliders is investigated with an emphasis on improving the top tagging efficiency and mass reconstruction of boosted top quarks.

Sensitivity of CLIC at 380 GeV to top FCNC decay t->cH

  • Speaker: Aleksander Filip Zarnecki (University of Warsaw), presented by Naomi van der Kolk (MPP, Munich)
  • Status: Accepted
  • Proposed time: 15+5min
  • Abstract: In the Standard Model, FCNC top decays, possible on loop level only, are very strongly suppressed. Observation of any such decay would be a direct signature of the physics beyond SM. Large enhancements are possible in many "new physics" scenarios and the largest enhancement is in most cases expected for t->cH decay. A full simulation study for CLIC was based on the WHIZARD simulation of FCNC top decays within the 2HDM(III) model. Beam polarization and beam induced background were taken into account. Top pair production events with FCNC decay t->cH can be identified based on the kinematic constrains and flavour tagging information. Due to the large overlap in kinematic space with standard top pair events, the final signal selection efficiency is small, at the 10% level. Expected limits on BR(t->cH)*BR(H->bb) are compared with earlier results based on parton level simulation.

Session: Simulation/Reconstruction/Detector-performance

Status of ECAL Optimization at CLIC

  • Speaker: Matthias Weber (CERN)
  • Status: Accepted
  • Proposed time: 15 +5 min.
  • Abstract: In this talk the ECAL optimization studies for the new CLIC detector model, using the DD4hep toolkit, are presented. The studies concentrate on the energy resolution performance of prompt photons and results are shown both on hit level and on PFO level after clustering and reconstruction.

Session: Vertex/Tracking

Session: Calorimeters/Muon

The CMS HGCAL upgrade project

  • Speaker: Matthias Weber (CERN)
  • Status: Accepted
  • Proposed time: 25+5 min
  • Abstract: Fine-grained calorimetry has been explored for future e+e- experiments at ILC and CLIC for several years. It provides improved jet energy resolution through particle flow analysis. CMS is developing high-granularity endcap calorimeters (HGCAL) for its HL-LHC upgrade. Similarly to the options studied for ILC and CLIC, the CMS HGCAL is based on silicon pad and scintillator+silicon photomultipliers readout. However, the challenges of HGCAL are rather different from ILC/CLIC detectors, particularly due to the unprecedented radiation environment of the HL-LHC - up to 10^16n/cm^2 at pseudorapidity |eta|=3. The talk gives an introduction to the CMS HGCAL project and shows first results from silicon sensor testing and test beam experiments.
