IR-Improved DGLAP-CS Parton Shower Effects in W+n Jets

Recent IR-Improved results for LHC/FCC physics

“…. Currently, in the Herwig6.5 [6] environment we have a realization of IR-improved parton showers in the MC Herwiri1.031 [7] by two of us (BFLW and SAY) which is elevated to the exact NLO shower/ME matched level via the MC@NLO [8] and via the MG5_aMC@NLO [9] frameworks as MC@NLO/Herwiri1.031 [10] and MG5_aMC@NLO/Herwiri1.031 [11], respectively, by three of us (AM, BFLW and SAY). In the Pythia8 [12] environment, we have the realization of IR-improved (IRI) Pythia8 [13] by one of us (BFLW) with its corresponding NLO shower/ME matched MG5_aMC@NLO/IRI-Pythia8.…”

Role of IR-Improvement in LHC/FCC Physics

“…Currently, we have a realization of IR-improved parton showers in the Herwig6.5 [3] environment in the MC Herwiri1.031 [4] by two of us (BFLW and SAY). Via the MC@NLO [5] and the MG5_aMC@NLO [6] frameworks this MC is elevated to the exact NLO shower/ME matched level as MC@NLO/Herwiri1.031 [7] and MG5_aMC@NLO/Herwiri1.031 [8], respectively.
