AMI Credentials

This twiki lists the standard samples being analysed in HTop analyses. It uses AMI hashtags to tag samples being used. To use this page, click the login button (ensuring your AMI/Grid certificate is linked to your browser, otherwise follow the link to CERN SSO on the right) and select the samples you are interested in. It is possible to generate a list of all samples in a category by clicking "Export".

Sample categories are initially stored in this spreadsheet before being tagged by the script stored in this repository.

  • Nominal ttH SM samples
    • Include ME and PS weights for ISR&FSR systematics, simulated in FS.
    • Also exist in AF2 as reference for systematics.
    • Includes all Higgs decay modes, one sample per ttbar decay mode.
  • Nominal tHjb SM samples, generated in the 4FS, simulated in AF2.
    • Includes all Higgs and top decay modes.
  • Nominal tWH SM samples, generated in the 5FS, simulated in AF2.
    • Includes all Higgs and top decay modes.
  • Alternative ttH SM sample, simulated in AF2.
    • To be used for NLO matching and parton shower systematic uncertainty.
    • Includes all Higgs decay modes, one sample per ttbar decay mode.

  • BSM signal samples are generated using the Higgs Characterisation model in MG5.
    • Samples are generated with CP-odd and CP-even mixing controlled by an alpha parameter listed as alpha_X, where the angle is defined in degrees (°), or listed with cos(alpha), listed as ca_X. These parameters are defined in the sample name.
    • ttH samples are simulated in AF2, include all Higgs decay modes, one sample per ttbar decay mode, and are generated with kt = 1.
    • tHjb BSM samples are generated in the 4FS and simulated in AF2. Includes all Higgs and top decay modes. kt can vary from -1 to 2.
    • tWH BSM sample are generated in the 5FS (despite the name stating they are 4FS), and are simulated in AF2. Includes all Higgs and top decay modes. kt can vary from -1 to 2.

  • Background samples are listed here for those of particular relevancy to ttH(bb) and ttH(ML) analyses with a focus on the latest/greatest setups.
