NLO Corrections to Hard Process in Parton Shower MC - KrkNLO Method
/ Jadach, S (Cracow, INP) ; Płaczek, W (Jagiellonian U.) ; Sapeta, S (Cracow, INP ; CERN) ; Siódmok, A (Cracow, INP) ; Skrzypek, M (Cracow, INP ; CERN)
A new method of combining an NLO-corrected hard process with an LO parton shower Monte Carlo, nicknamed {\sf KrkNLO}, was proposed recently. It is simpler than well-established two other methods: {\sf MC@NLO} and {\sf POWHEG}. [...]

Matching NLO QCD with parton shower in Monte Carlo scheme — the KrkNLO method
/ Jadach, S. (Cracow, INP) ; Płaczek, W. (Jagiellonian U.) ; Sapeta, S. (CERN) ; Siódmok, A. (Cracow, INP ; CERN) ; Skrzypek, M. (Cracow, INP)
A new method of including the complete NLO QCD corrections to hard processes in the LO parton-shower Monte Carlo (PSMC) is presented. This method, called KrkNLO, requires the use of parton distribution functions in a dedicated Monte Carlo factorization scheme, which is also discussed in this paper. [...]

Monte Carlo simulations of Higgs-boson production at the LHC with the KrkNLO method
/ Jadach, S. (Cracow, INP) ; Nail, G. (Manchester U. ; KIT, Karlsruhe, TP) ; Płaczek, W. (Jagiellonian U.) ; Sapeta, S. (CERN ; Cracow, INP) ; Siodmok, A. (CERN ; Cracow, INP) ; Skrzypek, M. (Cracow, INP)
We present numerical tests and predictions of the KrkNLO method for matching of NLO QCD corrections to hard processes with LO parton shower Monte Carlo generators (NLO+PS). This method was described in detail in our previous publications, where it was also compared with other NLO+PS matching approaches (MC@NLO and POWHEG) as well as fixed-order NLO and NNLO calculations.

Parton distribution functions in Monte Carlo factorisation scheme

A next step in development of the KrkNLO method of including complete NLO QCD corrections to hard processes in a LO parton-shower Monte Carlo (PSMC) is presented. It consists of generalisation of the method, previously used for the Drell-Yan process, to Higgs-boson production. [...]

Monte Carlo modelling of NLO DGLAP QCD evolution in the fully unintegrated form
/ Jadach, S (Cracow, INP ; CERN) ; Kusina, A (Cracow, INP) ; Skrzypek, M (Cracow, INP) ; Slawinska, M (Cracow, INP)
We are reporting on the ongoing effort of the Monte Carlo (MC) modelling of NLO DGLAP QCD evolution in the fully unintegrated form. The resulting parton shower MC is performing on its own the NLO QCD evolution, contrary to all known programs of this kind which are limited to LO level only. [...]

Reweighting Parton Showers

We report on the possibility of reweighting parton-shower Monte Carlo predictions for scale variations in the parton-shower algorithm. The method is based on a generalization of the Sudakov veto algorithm. [...]

Two real parton contributions to non-singlet kernels for exclusive QCD DGLAP evolution
/ Jadach, S (Cracow, INP ; CERN) ; Kusina, A (Cracow, INP) ; Skrzypek, M (Cracow, INP) ; Slawinska, M (Cracow, INP)
Results for the two real parton differential distributions needed for implementing next-to-leading order (NLO) parton shower Monte Carlo are presented. They are also integrated over the phase space in order to provide solid numerical control of the MC codes and for the discussion of the differences between the standard $\bar{MS}$ factorization and Monte Carlo implementation at the level of the inclusive NLO evolution kernels.
