Oriented Event Shapes for massive Quarks
In this work we present the computation of so-called oriented eventshape distributions for massive quarks up to 𝒪(αs), along with the total oriented cross section in which one does not look at the geometric properties of the momentum distribution for particles in the final state. We consider the vec...

| description | In this work we present the computation of so-called oriented eventshape distributions for massive quarks up to 𝒪(αs), along with the total oriented cross section in which one does not look at the geometric properties of the momentum distribution for particles in the final state. We consider the vector and axial-vector currents, and for the former, we find a non-vanishing result at 𝒪(α0s) that translates into a significant enhancement as compared to the massless approximation. Our results are an important ingredient for analyses that aim to determine the strong coupling with high accuracy. |
