NNPDF’s dataset naming convention

Each dataset implemented in NNPDF must have a unique name, which is a string constructed following this [Backus–Naur form]:

<valid set name> ::= <experiment> "_" <process> "_" <energy>
                   | <experiment> "_" <process> "_" <energy> "_" <extra_information>

<valid dataset name> ::= <set name> "_" <observable name>

<experiment> ::= "ATLAS" | "BCDMS" | "CDF" | "CHORUS" | "CMS" | "D0" | "DYE605" | "DYE866"
              | "DYE906" | "EMC" | "H1" | "HERA" | "LHCB" | "NMC" | "NNPDF" | "NUTEV" | "SLAC"
              | "ZEUS"

<process> ::= "1JET" | "2JET" | "CC" | "DY" | "INTEG" | "NC" | "PH" | "POS" | "SINGLETOP"
            | "TTBAR" | "WCHARM" | "WJ" | "WPWM" | "Z0" | "Z0J"

<energy> ::= <integer> <unit> | <integer> "P" <integer> <unit>  | "NOTFIXED"

<extra_information> ::= <string>

Experiments

  • ATLAS: A Large Toroidal Aparatus

  • BCDMS: TODO

  • CHORUS: TODO

  • CMS: Compact Muon Solenoid

  • E605: TODO

  • E866: TODO

  • E906: TODO

  • EMC: TODO

  • HERA <https://dphep.web.cern.ch/accelerators/hera>: Hadron Elektron Ring Anlage. While technically speaking this is an accelerator, this string is used for the combined analyses of H1 and ZEUS.

  • LHCB:

  • NMC: TODO

  • NNPDF: This experiment name is used for two purposes:

    1. for auxiliary datasets needed in the PDF fit, for instance INTEG and POS

    2. for predictions used in NNPDF papers to study the impact of PDFs in processes not included in its PDF fit

  • NUTEV: TODO

Processes

  • 1JET: single-jet inclusive production

  • 2JET: dijet production

  • CC: DIS charged-current

  • Z0: lepton-pair production (neutral current off-shell Drell–Yan)

  • H: on-shell Higgs-boson production

  • HVBF: production of an on-shell Higgs-boson with two jets (vector-boson fusion)

  • INTEG: auxiliary dataset for integrability constraints; only valid for NNPDF experiment

  • NC: DIS neutral-current

  • POS: auxiliary dataset for positivity constraints; only valid for NNPDF experiment

  • TTBAR: top–anti-top production

  • WM: production of a single negatively-charged lepton (charged current off-shell Drell–Yan)

  • WMWP: production of two opposite-sign different flavor leptons (W-diboson production)

  • WP: production of a single positively-charged lepton (charged current off-shell Drell–Yan)

  • WPZ: production of three leptons (WZ-diboson production)

  • Z0PT: production of two same-flavor opposite-sign leptons with non-zero total transverse momentum (Z-boson pt spectrum)
