在超对称理论中，顶夸克和底夸克的标量伙伴被认为是最轻的夸克，在强子对撞机中具有潜在的大截面。我们提出的预测生产的顶部和底部的平方在Tevatron和大型强子对撞机，包括次领先的阶修正超对称QCD和重申软胶子发射次领先对数精度。我们讨论了高阶修正对总截面和横动量分布的影响，并提供了由于尺度变化和部分子分布函数的理论不确定性的估计。
The scalar partners of top and bottom quarks are expected to be the lightest squarks in supersymmetric theories, with potentially large cross sections at hadron colliders. We present predictions for the production of top and bottom squarks at the Tevatron and the LHC, including next-to-leading order corrections in supersymmetric QCD and the resummation of soft gluon emission at next-to-leading-logarithmic accuracy. We discuss the impact of the higher-order corrections on total cross sections and transverse-momentum distributions, and provide an estimate of the theoretical uncertainty due to scale variation and the parton distribution functions.
