Top-quark pair production at the LHC: fully differential QCD predictions at NNLO [PDF]

open access: yesJournal of High Energy Physics, 2019
We report on a new fully differential calculation of the next-to-next-to-leading-order (NNLO) QCD radiative corrections to the production of top-quark pairs at hadron colliders. The calculation is performed by using the qT subtraction formalism to handle

Ponderomotive effects in multiphoton pair production [PDF]

open access: yes, 2016
The Dirac-Heisenberg-Wigner formalism is employed to investigate electron-positron pair production in cylindrically symmetric but otherwise spatially inhomogeneous, oscillating electric fields.

Studies of gluon TMDs and their evolution using quarkonium-pair production at the LHC [PDF]

open access: yesThe European Physical Journal C, 2019
$$J/\psi $$ J / ψ - or $$\Upsilon $$ Υ -pair production at the LHC are promising processes to study the gluon transverse momentum distributions (TMDs) which remain very poorly known.

On the production of electron pairs [PDF]

open access: yesProceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1936
The production of positive-negative electron pairs by a beam of γ-rays traversing matter has been examined by various authors, the most comprehensive treatment being that of Bethe and Heitler. These authors employ the usual "Born Approximation" method, and justify its use for such elements as lead by pointing out that for γ-rays in the ...

Pair Production in AGN [PDF]

open access: yesSymposium - International Astronomical Union, 1989
The X-ray luminosity and variability of many AGN are sufficiently extreme that any hard γ-rays produced in the source will collide with the X-rays and create electron-positron pairs, rather than escape. A small region where vast amounts of energy are produced, such as an AGN, is an ideal place to accelerate particles to relativistic energies and so ...

Search for Resonant and Nonresonant Higgs Boson Pair Production in the bb[over ¯]τ^{+}τ^{-} Decay Channel in pp Collisions at sqrt[s]=13  TeV with the ATLAS Detector. [PDF]

open access: yesPhysical Review Letters, 2018
A search for resonant and nonresonant pair production of Higgs bosons in the bb[over ¯]τ^{+}τ^{-} final state is presented. The search uses 36.1  fb^{-1} of pp collision data with sqrt[s]=13  TeV recorded by the ATLAS experiment at the LHC in 2015 and ...

W-Pair Production with YFSWW/KoralW [PDF]

open access: yes, 2000
A theoretical description of W-pair production in terms of two complementary Monte Carlo event generators YFSWWand KoralW is presented. The way to combine the results of these two programs in order to get precise predictions for WW physics at LEP2 and LC

Analytic results for the planar double box integral relevant to top-pair production with a closed top loop [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractIn this article we give the details on the analytic calculation of the master integrals for the planar double box integral relevant to top-pair production with a closed top loop. We show that these integrals can be computed systematically to all
