Analysis
The article likely presents a theoretical physics study, focusing on quantum chromodynamics (QCD) calculations. Specifically, it investigates higher-order corrections to the quark form factor, which is a fundamental quantity in particle physics. The notation $\mathcal{O}(α_s^2 α)$ suggests the calculation of terms involving the strong coupling constant ($α_s$) to the second order and the electromagnetic coupling constant ($α$) to the first order. This kind of research is crucial for precision tests of the Standard Model and for searching for new physics.
