Bu çalışma, Büyük Hadron Çarpıştırıcısı (BHÇ) ve Gelecekteki Dairesel Çarpıştırıcı (FCC) için 14, 27 ve 100 TeV kütle merkez enerjilerinde Wbb ̅ üretim kanalının leading order (LO) ve next-to-leading order (NLO) kuantum renk dinamiği (QCD) tesir kesitlerini sunmaktadır. Sayısal sonuçları elde etmek için beş farklı parton dağıtım fonksiyonu (PDF) kullanılmış ve PDF hataları MCFM Monte Carlo programı ile elde edilmiştir. Ayrıca renormalizasyon ve faktörizasyon ölçeklerinin farklı değerleri için scale hata payı hesaplaması yapılmıştır. W üretim kanalında elde edilen scale hata paylarının aksine Wbb ̅ üretim kanalında NLO QCD'deki scale hata payları LO QCD’deki scale hata paylarından daha yüksek bulunmuştur. Artan enerjinin hata payları üzerindeki etkisini test etmek için, artan enerji ile scale, PDF ve α_S belirsizliklerinin karşılaştırılması yapılmıştır. Ayrıca, bu çalışmada kullanılan simülasyon kodunun doğruluğunu onaylamak için √s=7 TeV enerji değerinde elde edilen sonuçlar ile aynı enerjideki CMS verileri karşılaştırılmıştır. Yazılmış olan kodların doğruluğunun onaylanmasından sonra, Wbb ̅ üretim kanalının √s= 14, 27 ve 100 TeV'deki LO ve NLO QCD tesir kesitleri hesaplanmıştır. Daha sonra √s= 7 TeV enerjisindeki veri ile aynı istatistiğe sahip verinin elde edilmesi için √s= 14, 27 ve 100 TeV enerjilerinde ihtiyaç duyulan veri miktarı hesaplanmıştır.
