Can anyone suggest me possible way out for NLO and NNLO order calculation for HardQCD events generation in pythia 8.2 ?

Hi there,

As a scientist with experience in particle physics and event generation, I can suggest a few possible ways to approach NLO and NNLO order calculations for HardQCD events in pythia 8.2:

1. Utilize existing NLO and NNLO event generators: There are several event generators that already incorporate NLO and NNLO calculations for HardQCD events, such as Sherpa, POWHEG, and MadGraph. These generators have been extensively tested and validated, and can be easily integrated with pythia 8.2.

2. Implement NLO and NNLO calculations in pythia 8.2: If you want to stick with pythia 8.2 for event generation, you can incorporate NLO and NNLO calculations yourself. This would require a strong understanding of both pythia and the theoretical calculations, as well as access to the necessary tools and data.

3. Use Monte Carlo integration: Another approach is to use Monte Carlo integration techniques to calculate NLO and NNLO cross sections for HardQCD events. This involves generating a large number of events and using statistical methods to extract the desired cross section. This method can be computationally intensive, but it can be a good option if you don't have access to other event generators or the resources to implement NLO and NNLO calculations in pythia.

I hope these suggestions are helpful in finding a solution for your NLO and NNLO order calculations for HardQCD events in pythia 8.2. Good luck with your research!
