Production of charged H+ (with different masses) associated with W- using MG5_aMC_v2_6_1 at LO QCD. The cross sections are for tan(beta)=9.7. NNPDF23_LO used for PDF. Pythia6 is used for showering and hadronization. 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. 10,000 events per file.

Decays

Associated W decays to lepton-neutrino. Charged H+ decays to tb~ quarks.
