Top-pair production in hadron collisions at NNLL

EPJ Web of Conferences, 2013
We present results for the total top-pair production cross section at the Tevatron and the LHC. Our predictions supplement fixed-order results with resummation of soft logarithms and Coulomb singularities to next-to-next-to-leading logarithmic accuracy ...

Updated predictions for toponium production at the LHC

Physics Letters B
We provide an update on QCD predictions for top-quark pair production close to threshold including bound state effects at the Large Hadron Collider. We compute the top-quark pair invariant mass distribution dσ/dMtt¯, including Coulomb resummation for ...

BFKL resummation effects in γ*γ* → ρρ

, 2006
We calculate the leading order BFKL amplitude for the exclusive diffractive process  in the forward direction, which can be studied in future high energy e  +  e - linear colliders.

All order merging of high energy and soft collinear resummation

SciPost Physics Proceedings
We present a method of merging the exclusive LO-matched high energy resummation of High Energy Jets (HEJ) with the parton shower of PYTHIA which preserves the accuracy of the LO cross sections and the logarithmic accuracy of both resummation schemes ...

Effective Field Theory Techniques for Resummation in Jet Physics [PDF]

, 2012
In this thesis, we present several new techniques for the resummation of observables relevant to jet physics at the LHC using effective field theory techniques.

Rapidity resummation for B -meson wave functions

, 2014
Transverse-momentum dependent (TMD) hadronic wave functions develop light-cone divergences under QCD corrections, which are commonly regularized by the rapidity ζ of gauge vector defining the non-light-like Wilson lines.

Critical Permeability from Resummation

Axioms
Special calculation methods are presented for critical indices and amplitudes for the permeability of thin wavy channels dependent on the waviness. The effective permeability and wetted perimeter of the two-dimensional random percolating media are considered as well.
