The soft limits of scattering amplitudes have been extensively studied due to their essential
role in the computation of physical observables in collider physics. The universal …

We provide a concise overview on transverse momentum dependent (TMD) parton
distribution functions, their application to topical issues in high-energy physics …

The series Lecture Notes in Physics (LNP), founded in 1969, reports new developments in
physics research and teaching-quickly and informally, but with a high quality and the explicit …

A bstract We show that color-kinematics duality is present in tree-level amplitudes of
quantum chromodynamics with massive flavored quarks. Starting with the color structure of …

We present the three-loop result for the soft anomalous dimension governing long-distance
singularities of multileg gauge-theory scattering amplitudes of massless partons. We …

Infrared divergences in the perturbative expansion of gauge theory amplitudes and cross
sections have been a focus of theoretical investigations for almost a century. New insights …

We apply recently developed path integral resummation methods to perturbative quantum
gravity. In particular, we provide supporting evidence that eikonal graviton amplitudes …

The structure of scattering amplitudes in supergravity theories continues to be of interest.
Recently, the amplitude for 2→ 2 scattering in N= 8 supergravity was presented at three-loop …

A bstract The soft anomalous dimension governs the infrared singularities of scattering
amplitudes to all orders in perturbative quantum field theory, and is a crucial ingredient in …

A bstract We present an operator based factorization formula for the transverse energy-
energy correlator in the back-to-back (dijet) region, and uncover its remarkable perturbative …
