Signatures beyond benchmark models

Conveners: Riccardo Torre (TH) and Tobias Golling (EXP)

Ongoing studies

  • Resonances at 100 TeV: jets vs leptons (R.Torre et al)
    • Goal of the project:
    • Status: looking for experimental collaborators to carry out simulations
    • Slides

  • Running Electroweak Couplings as BSM probes (J.Rudermann et al)
    • Goal of the project: Use DY XS to measure EW coupling running, measure EW beta function.
    • Status: looking for experimental collaborators to carry out simulations
    • Paper

  • Top dipole moments (JA Aguilar Saavedra et al)
    • Goal of the project: use high mass t-tbar production to probe top's anomalous dipole moments
    • Status: looking for experimental collaborators to carry out simulations
    • Paper

  • Heavy resonances in t-tbar decays (S. Chekanov et al)
    * Goal of the project: Set sensitivity limits on Zprime/gkk and other resonances using boosted jet techniques and b-tagging.
    • Status: Paper is in PRD (in press) arXiv:1412.5951 "Sensitivity to new high-mass states decaying to ttbar at a 100 TeV collider" by B. Auerbach, S. Chekanov, J. Love, J. Proudfoot and A.V. Kotwal
    • Recent slides explaining the analysis at the IAS meeting. Jan 28, 2015.
    • Monte Carlo samples have been created using HepSim repository
    • In progress: Processing with a fast detector simulation using HepSim and Delphes

  • Right-handed currents and doubly charged Higgs bosons (J. Gluza et al)
    • Goal of the project:
      • finding mass benchmarks and branching ratios for Higgs bosons within various scenarios containing triplet scalar fields, taking into account correlations between model parameters and constraints coming from low energy processes (e.g. LFV)
      • investigating production and decay processes at FCC-hh, FCC-eh, FCC-ee with a focus on phenomenology of doubly charged Higgs bosons
      • investigating possible ways to discriminate among different models with Higgs triplet particles
    • Status: ongoing, with some first results (see slides)
    • Slides

  • Electroweak precision tests at FCC-hh (G. Panico et al.)
    • Goal of the project:
      • use high mass di-lepton and di-jet distributions to indirectly constrain heavy new physics (e.g., assuming universal couplings, constrain new physics from contributions to oblique parameters with sensitivity enhances by large invariant masses, e.g. V, X, Y, W and Z)
    • Status: ongoing

Some Monte Carlo samples 100 TeV:

Some truth-level event samples for 100 TeV pp collisions can be downloaded from the HepSim Monte Carlo event catalog. Look at 100 TeV event samples that include BSM signals and SM backgrounds. A short description of how to download and run over events can be found here. One can run over the truth-level samples using the Delphes fast simulation as explained here.
