L0Muon Event model

see L0Muon event model

L0Muon Emulator

The L0Muon emulator emulates the L0Muon trigger processing.

It is based on 2 main generic classes : Unit and Register which are defined in L0/ProcessorKernel package (LHCb project).

These classes are specialized in L0/L0MuonKernel where is implemented the L0Muon processing.

The emulator runs in L0MuonAlg. It is configured using the L0MuonKernel.xml file in the PARAM/ParamFilesParam.

L0Muon banks decoding

The decoding runs in L0MuonCandidatesFromRaw. It is configured using the L0MuonKernel.xml file in the PARAM/ParamFiles package. The decoding also depends on L0/L0MuonKernel.

  • The L0Muon bank content is described in EDMS818559.

L0Muon main packages

LHCb project

This package contains generic classes used by the L0Muon emulator and decoding software :
  • Register : contains a boost::dynamic_bitset.
  • TileRegister : special Register which contains in addition a list of MuonTileID associated to the bitset.
  • RegisterFactory : factory owning the registers. 3 different instances of the RegisterFactory may be created.
  • Unit : a Unit contains :
    • a list of pointers to registers used as inputs
    • a list of pointers to registers used as outputs
    • a list of pointer to 'child'-units (thus, the units forms a hierarchical strucuture).
    • a set of virtual methods where specialized units (see L0/L0MuonKernel) will perform specific tasks using the input registers and fill their output registers
      • initialize
      • preexecute
      • execute
      • postexecute
      • finalize
  • UnitFactory :

Lbcom project


  • L0MuonAlg : algorithm to run the L0Muon emulator.

L0Muon additional packages

This package is used to fill the L0Muon configuration data base (see EDMS818447).
