Resummation of Nonalternating Divergent Perturbative Expansions [PDF]

, 2000
A method for the resummation of a nonalternating divergent perturbation series is described. The procedure constitutes a generalization of the Borel-Padã method.

Soft Gluon Resummation in Heavy Flavour Production [PDF]

, 1996
I discuss the effect of resummation of soft gluons in hadronic production of high mass systems, and in particular in heavy flavour production. I show that in widely used $x$-space resummation formulae, spurious terms that grow factorially in the order of

Resummation of Cactus Diagrams in Lattice QCD

, 1998
We show how to perform a resummation, to all orders in perturbation theory, of a certain class of gauge invariant diagrams in Lattice QCD. These diagrams are often largely responsible for lattice artifacts.

Snowmass 2021 White Paper: Resummation for future colliders

, 2022
Resummation techniques are essential for high-precision phenomenology at current and future high-energy collider experiments. Perturbative computations of cross sections often suffer from large logarithmic corrections, which must be resummed to all ...

Jettiness formulation of the MiNNLOPS method

Journal of High Energy Physics
We present a new formulation of the MiNNLOPS method to match NNLO QCD calculations with parton showers by using jettiness as a resummation variable. The full derivation for colour-singlet processes is presented using 0-jettiness starting from the NNLL ...

High-energy resummation in heavy-quark pair photoproduction

Physics Letters B, 2018
We present our predictions for the inclusive production of two heavy quark–antiquark pairs, separated by a large rapidity interval, in the collision of (quasi-)real photons at the energies of LEP2 and of some future electron–positron colliders.

Electroweak Vector Boson Production in Joint Resummation [PDF]

, 2002
We study the application of the joint resummation to electroweak boson production at hadron colliders. The joint resummation formalism resumes both threshold and transverse momentum corrections to the transverse momentum distribution at, next-to-leading ...

Resummation for Nonequilibrium Perturbation Theory and Application to Open Quantum Lattices

Physical Review X, 2016
Lattice models of fermions, bosons, and spins have long served to elucidate the essential physics of quantum phase transitions in a variety of systems. Generalizing such models to incorporate driving and dissipation has opened new vistas to investigate ...

Tadpole resummations in string theory

Physics Letters B, 2008
While R-R tadpoles should be canceled for consistency, string models with broken supersymmetry generally have uncanceled NS-NS tadpoles. Their presence signals that the background does not solve the field equations, so that these models are in "wrong" vacua.
