论文摘要
我们提出了使用LHC的Atlas实验的各种测量值来确定Parton分配功能的拟合，包括包括$ W $和$ Z $ BOSON生产，$ t \ bar {T} $生产，$ W $+JETS和$ Z $+JETS生产，包含JET生产和Direct Photon Producation。这些地图集的测量结果与来自电子 - 普罗顿对撞机Hera的深无弹性散射数据结合使用。特别注意各种地图集数据集内和之间的系统不确定性以及模型，理论和参数不确定性的影响。
We present fits to determine Parton Distribution Functions using a diverse set of measurements from the ATLAS experiment at the LHC, including inclusive $W$ and $Z$ boson production, $t\bar{t}$ production, $W$+jets and $Z$+jets production, inclusive jet production and direct photon production. These ATLAS measurements are used in combination with deep-inelastic scattering data from the electron-proton collider HERA. Particular attention is paid to the correlation of systematic uncertainties within and between the various ATLAS data sets and to the impact of model, theoretical and parameterisation uncertainties.
