Determination of Parton Distribution Functions with Jets at Forward Rapidity Region Using xFitter Analysis Framework
Abstract
Parton distribution functions (PDF), which have to be determined from the measurements, are one of the main components to define the physics that occurs at the hadron colliders. In this study, a quantum chromodynamics (QCD) analysis was performed at the next-to-leading order (NLO) in the xFitter framework which is an open source QCD fit platform. Along with the HERA1+2 DIS and the jet differential cross-section data measured in the forward rapidity region (3.2 < |y| < 4.7) of the CMS detector in the LHC in proton-proton collisions at s = 8 TeV were used in xFitter analysis framework. Particularly gluon distribution functions were emphasized.

xFitter Analiz Çerçevesi Kullanılarak İleri Rapidite Bölgesinde Jetler ile Parton Dağılım Fonksiyonlarının Belirlenmesi
Abstract
Ölçümlerden belirlenmesi gereken parton dağılım fonksiyonları (PDF), hadron çarpıştırıcılarında meydana gelen fiziği tanımlayan ana bileşenlerden biridir. Bu çalışmada, açık kaynak kodlu bir kuantum renk dinamiği (QCD) fit platformu olan xFitter çerçevesinde ikincil mertebeden (NLO) bir QCD analizi yapılmıştır. HERA1+2 DIS ile birlikte s = 8 TeV'de proton-proton çarpışmalarında LHC'deki CMS dedektörünün ileri rapidite bölgesinde (3.2 < |y| < 4.7) ölçülen jetlerin diferansiyel tesit kesit verileri xFitter analiz çerçevesinde kullanılmıştır. Özellikle gluon dağılım fonksiyonları üzerinde durulmuştur.
