微分重夸克产生系数函数的小$x$重化

Small-$x$ resummation in coefficient function for differential heavy-quarks production

Federico Silvetti

摘要:

当散射过程的典型能量标度$Q$与可用总质心能量$s$之间的比率$x = \frac{Q^2}{s}$小时,高能对数校正被增强。我们讨论了它们在快度、横动量和不变质量的微分截面中的再表示及其在LHC重味产生中的应用。

英文摘要:

High-energy logarithmic correction are enhanced when the ratio, $x = \frac{Q^2}{s}$ between the typical energy scale of a scattering process $Q$ and the total centre of mass energy available $s$ is small. We discuss recent developments on their resummation in differential cross sections in rapidity, transverse momentum and invariant mass and their application to heavy flavour production at the LHC.
