What the study found
The study finds that next-to-leading power contributions in the threshold variable can be significant for inclusive slepton pair production. It also reports that existing calculations may underestimate the scale error for large slepton masses.
Why the authors say this matters
The authors note that cross sections near threshold are sensitive to large logarithmic terms that must be resummed to all orders in perturbation theory. The study suggests that including next-to-leading power effects is important for assessing the reliability of predictions, especially for large slepton masses.
What the researchers tested
The researchers evaluated the next-to-leading power contribution in the threshold variable to leading logarithmic accuracy for inclusive slepton pair production at hadron colliders. They also included results for a potential future FCC-hh machine at 85 TeV.
What worked and what didn't
The next-to-leading power contributions were found to be significant compared with the next-to-leading logarithmic terms at leading power. The abstract also states that existing calculations underestimate the scale error for large slepton masses.
What to keep in mind
The available summary does not describe detailed numerical values, experimental data, or a full comparison across all parameter ranges. It also does not provide additional limitations beyond the focus on leading logarithmic accuracy and the specific collider scenarios studied.
