Description
Precise theoretical predictions of QCD scattering and radiation
processes are fundamental building blocks for the LHC precision
program. Fixed-order computations must be supplemented by all-order
resummations where logarithmically-enhanced contributions become
large. Among those, small-$x$ logarithms 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.
These corrections are important for several processes within the
kinematical range of the LHC, including heavy flavour production,
Higgs production in gluon fusion and Drell-Yan. This talk will discuss
recent developments on small-$x$ resummation in differential cross
sections in rapidity, transverse momentum and invariant mass and their
application to heavy flavour production at the LHC and Parton
Distribution Function determination. Additionally, an extension of the
resummation of next-to-leading logarithms for inclusive cross sections
will be presented, using a Higgs-induced Deep Inelastic Scattering as
an explicit case study.
