论文摘要
我们考虑在质子质子碰撞中产生一个重夸克对。对于底部和魅力夸克，最终状态不变的质量通常比对撞机能量（例如在LHC上）小得多，因此高能量对数可能会破坏固定顺序的理论预测的扰动。因此，需要将这些对数重新召集到所有订单以获得可靠的预测。在这项工作中，我们将以前的结果扩展到高能（或小$ x $）重新庆典上，以迅速，横向动量和不变质量的差分分布，并在公共代码地狱中实施。
We consider the production of a heavy quark pair in proton-proton collisions. For bottom and charm quarks, the final state invariant mass is typically much smaller than the collider energy (e.g. at the LHC), so that high-energy logarithms may spoil the perturbativity of the theoretical prediction at fixed order. The resummation of these logarithms to all orders is thus needed to obtain reliable predictions. In this work, we extend previous results on high-energy (or small-$x$) resummation to differential distributions in rapidity, transverse momentum and invariant mass, and implement them in the public code HELL.
