Multi-loop amplitudes and resummation [PDF]
Physics Letters B, 2003 We explore the relation between resummation and explicit multi-loop calculations for QCD hard-scattering amplitudes. We describe how the factorization properties of amplitudes lead to the exponentiation of double and single poles at each order of perturbation theory. For these amplitudes, previously-observed relations between single and double poles in

Borel resummation of transverse momentum distributions [PDF]
, 2008 We present a new prescription for the resummation of contributions due to soft gluon emission to the trasverse momentum distribution of processes such as Drell-Yan production in hadronic collisions.

Resummations and non-perturbative corrections [PDF]
Journal of High Energy Physics, 2015 We consider a generalization of the Borel resummation, which turns out to be equivalent to the standard Borel resummation. We apply it to the simplest large N duality between the pure Chern-Simons theory and the topological string on the resolved conifold, and find a simple integral formula for the free energy.

Momentum conservation and unitarity in parton showers and NLL resummation
Journal of High Energy Physics, 2018 We present a systematic study of differences between NLL resummation and parton showers. We first construct a Markovian Monte-Carlo algorithm for resummation of additive observables in electron-positron annihilation.

Leading Logarithm Quantum Gravity
UniverseThe continual production of long wavelength gravitons during primordial inflation endows graviton loop corrections with secular growth factors. During a prolonged period of inflation, these factors eventually overwhelm the small loop-counting parameter ...

Hadron-in-jet production at partonic threshold
Journal of High Energy Physics, 2020 We consider the longitudinal momentum distribution of hadrons inside jets in proton-proton collisions. At partonic threshold large double logarithmic corrections arise which need to be resummed to all orders.

Groomed jet mass at high precision
Physics Letters B, 2020 We present predictions of the distribution of groomed heavy jet mass in electron-positron collisions at the next-to-next-to-leading order accuracy matched with the resummation of large logarithms to next-to-next-to-next-to-leading logarithmic accuracy ...
