Production of charged Higgs (H-) (with different masses) associated with t (top) using MG5_aMC_v2_6_1 at LO QCD. PYTHI8 is used for H+ decays, parton shower and hadronisation. The cross sections are for tan(beta)=1-7. NNPDF23_LO used for PDF. It uses 5 flavour number scheme (b-quark is a part of proton PDF). Pythia8 is used for showering and hadronisation. H+ masses ranged from 500 GeV to 8000 GeV (included to the names of files as *_m[MASS]). Cross section for each file depends on generated masses. 5,000 events per file. LHE events from MG5 are in "tev13_mg5_HT5F.tgz" Samples are created with the help of Xiaoping Wang and Carlos E.M. Wagner.

Decays

Decays of H+ are performed by PYTHIA8. Events are created assuming charged Higgs decay to SM Higgs and W+/- in 100% cases. SM Higgs decays to bbbar. To create realistic cross sections, you should multiply the obtained cross sections by the branching ratio of [H+ -> H0W], and multiply by the SM Higgs branching of 0.584 for [H0 -> bbar].

Slimming

Particle records are slimmed (all stable with pT>0.3 GeV) and (PID=5 || PID=6) or PID>22 && PID<38) or PID>10 && PID<17).
