For no PU, I usually generate TTbar events.

How to add dynamic inefficiency

The tag is set when the db file is generated.

# Add dynamic inefficiency to simulate dcol losses
dynIneff_db     = 'sqlite_file:phase1_efficiencies_95_pure.db'
dynIneff_tag    = 'SiPixelDynamicInefficiency_v1'

process.DynIneffReader = cms.ESSource("PoolDBESSource",
    DBParameters = cms.PSet(
        messageLevel = cms.untracked.int32(0),
        authenticationPath = cms.untracked.string('')),
    toGet = cms.VPSet(cms.PSet(
        record = cms.string("SiPixelDynamicInefficiencyRcd"),
        tag = cms.string(dynIneff_tag))),
    connect = cms.string(dynIneff_db))
process.dynineffprefer = cms.ESPrefer("PoolDBESSource", "DynIneffReader")
