Description
Expanding previous ATLAS analysis at lower energies, the high mass DY analysis aims to study the single- and double-differential cross section of the Drell-Yan production of dileptons in the range m_{ll}>116 GeV, exploring a phase space crucial to set constraints on the parton distribution functions (PDFs), covering a wide range of the proton’s momentum fraction.
The large dilepton invariant mass range that this analysis covers allows us to search for shape deviations introduced by high-dimensional operators, whose effects are suppressed by powers of the new physics energy scale (Λ), in the context of Effective Field Theory (EFT) interpretations.
