Spin and polarization effects on the nonlinear Breit–Wheeler pair production in laser-plasma interaction

open access: yesNew Journal of Physics, 2021
The spin effect of electrons/positrons ( e ^− / e ^+ ) and polarization effect of γ photons are investigated in the interaction of two counter-propagating linearly polarized laser pulses of peak intensity 8.9 × 10 ^23 W cm ^−2 with a thin foil target ...

Combination of Searches for Higgs Boson Pair Production in Proton-Proton Collisions at sqrt[s]=13  TeV. [PDF]

open access: yesPhysical Review Letters, 2018
This Letter describes a search for Higgs boson pair production using the combined results from four final states: bbγγ, bbττ, bbbb, and bbVV, where V represents a W or Z boson.

Search for pair production of vector-like quarks in the fully hadronic final state [PDF]

open access: yes, 2019
The results of two searches for pair production of vector-like T or B quarks in fully hadronic final states are presented, using data from the CMS experiment at a center-of-mass energy of 13 TeV.

NNLO QCD + NLO EW with Matrix+OpenLoops: precise predictions for vector-boson pair production [PDF]

open access: yesJournal of High Energy Physics, 2019
We present the first combination of NNLO QCD and NLO EW corrections for vector-boson pair production at the LHC. We consider all final states with two, three and four charged leptons, including resonant and non-resonant diagrams, spin correlations and ...

A Short Note On The Electron-Positron Pair Creation

open access: yesSemina: Ciências Exatas e Tecnológicas, 2017
The electron-positron pair creation is one of the various mechanisms of interaction of photon radiation with matter and the pair can be produced when the photon interacts with an atomic nucleus or an electron.

Vector-boson fusion Higgs pair production at N3LO [PDF]

open access: yesPhysical Review D, 2018
We calculate the next-to-next-to-next-to-leading order (N3LO) QCD corrections to vector-boson fusion (VBF) Higgs pair production in the limit in which there is no partonic exchange between the two protons.

Higher Order Corrections to Spin Correlations in Top Quark Pair Production at the LHC. [PDF]

open access: yesPhysical Review Letters, 2019
We calculate, for the first time, the next-to-next-to-leading order (NNLO) QCD corrections to spin correlations in top quark pair production at the LHC.

Higgs boson pair production at future hadron colliders: From kinematics to dynamics [PDF]

open access: yesPhysical Review D, 2018
The measurement of triple Higgs coupling is a key benchmark for the Large Hadron Collider (LHC) and future colliders. It directly probes the Higgs potential and its fundamental properties in connection to new physics beyond the Standard Model.

Search for Higgs boson pair production in the γ γ bb¯ final state with 13 TeV pp collision data collected by the ATLAS experiment [PDF]

open access: yes, 2018
A search is performed for resonant and non-resonant Higgs boson pair production in the γ γ bb¯ final state. The data set used corresponds to an integrated luminosity of 36.1 fb−1 of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded ...

Total top-quark pair-production cross section at hadron colliders through O(αS(4)). [PDF]

open access: yesPhysical Review Letters, 2013
We compute the next-to-next-to-leading order (NNLO) quantum chromodynamics (QCD) correction to the total cross section for the reaction gg → tt + X. Together with the partonic channels we computed previously, the result derived in this Letter completes ...
