Critical Schwinger pair production [PDF]

open access: yesPhysical Review Letters, 2015
We investigate Schwinger pair production in spatially inhomogeneous electric backgrounds. A critical point for the onset of pair production can be approached by fields that marginally provide sufficient electrostatic energy for an off-shell long-range ...

Z Boson Pair-Production at LEP [PDF]

open access: yesPhysics Letters B, 2003
Events stemming from the pair-production of Z bosons in e^+e^- collisions are studied using 217.4 pb^-1 of data collected with the L3 detector at centre-of-mass energies from 200 GeV up to 209 GeV.

Schwinger pair production in AdS2 [PDF]

open access: yesJournal of High Energy Physics, 2005
We analyze the pair production of charged particles in two-dimensional Anti-de Sitter space (AdS_2) with a constant, uniform electric field. We compute the production rate both at a semi-classical level, viewing Schwinger pair production as a tunneling ...

Novel leptoquark pair production at LHC [PDF]

open access: yesJournal of High Energy Physics, 2021
We introduce a novel mechanism for the leptoquark pair production at LHC that is of a t-channel topology and is quark-quark initiated. This mechanism operates under fairly general conditions.

Asymmetric leptoquark pair production at LHC

open access: yesJournal of High Energy Physics, 2023
We investigate asymmetric leptoquark pair production mechanism at the Large Hadron Collider to advocate its potential relevance to establish reliable constraints on the leptoquark parameter space and its ability to aid in correct identification of these ...

Leptoquark Pair Production at $ep$ Colliders [PDF]

open access: yesModern Physics Letters A, 1994
The pair production cross section for scalar and vector leptoquarks at $ep$ colliders is calculated for the case of photon--gluon fusion. In a model independent analysis we consider the most general $C$ and $P$ conserving couplings of gluons and photons ...

Kaon pair production close to threshold [PDF]

open access: yesPhysics Letters B, 2006
The total cross section of the reaction pp->ppK+K- has been measured at excess energies Q=10 MeV and 28 MeV with the magnetic spectrometer COSY-11.

The inverse problem for Schwinger pair production

open access: yesPhysics Letters B, 2016
The production of electron–positron pairs in time-dependent electric fields (Schwinger mechanism) depends non-linearly on the applied field profile. Accordingly, the resulting momentum spectrum is extremely sensitive to small variations of the field ...

NNLO QCD corrections to leptonic observables in top-quark pair production and decay [PDF]

open access: yesJournal of High Energy Physics, 2020
We calculate a comprehensive set of spin correlations and differential distributions in top-quark pair production and decay to dilepton final states. Our calculation is performed in the Narrow Width Approximation.
