CASCADE3 A Monte Carlo event generator based on TMDs
European Physical Journal C: Particles and Fields, 2021 The Cascade3 Monte Carlo event generator based on Transverse Momentum Dependent (TMD) parton densities is described. Hard processes which are generated in collinear factorization with LO multileg or NLO parton level generators are extended by adding ...

Pion generalized parton distributions and light-front wave functions in the Nambu–Jona-Lasinio model
Nuclear Physics B, 2021 Pion generalized parton distributions and light-front wave functions are investigated in the framework of Nambu–Jona-Lasinio model. The properties of pion generalized parton distributions and light-front wave functions are examined separately. Proceeding

Quantum walk approach to simulating parton showers [PDF]
Physical Review D, 2021 This paper presents a novel quantum walk approach to simulating parton showers on a quantum computer. We demonstrate that the quantum walk paradigm offers a natural and more efficient approach to simulating parton showers on quantum devices, with the ...

Parton distributions for the LHC [PDF]
, 2007 We present updated leading-order, next-to-leading order and next-to-next-to-leading order parton distribution functions (“MSTW 2008”) determined from global analysis of hard-scattering data within the standard framework of leading-twist fixed-order ...

Parton Distributions in Nucleons and Nuclei [PDF]
Annual Review of Nuclear and Particle Science, 2020 We review the current status of parton distribution function (PDF) determinations for unpolarized and longitudinally polarized protons and for unpolarized nuclei, which are probed by high-energy hadronic scattering in perturbative quantum chromodynamics (

Parton Showers beyond Leading Logarithmic Accuracy. [PDF]
Physical Review Letters, 2020 Parton showers are among the most widely used tools in collider physics. Despite their key importance, none so far have been able to demonstrate accuracy beyond a basic level known as leading logarithmic order, with ensuing limitations across a broad ...

Polarized parton distributions [PDF]
Physical Review D, 1995 We analyze spin dependent parton distributions consistent with the most recent measurements of the spin dependent deep inelastic scattering structure functions and obtained in the framework of the spin dilution model. Predictions for the doubly polarised proton-proton Drell-Yan asymmetry, for the high $p_{T}$ photon production mechanism and $J ...

An analysis of polarized parton distribution functions with nonlinear QCD evolution equations
Nuclear Physics B, 2022 We present the polarized parton distribution functions from a QCD analysis of the worldwide polarized deep inelastic scattering data, based on the dynamical parton distribution model.

High energy leptonic collisions and electroweak parton distribution functions [PDF]
Physical Review D, 2020 In high-energy leptonic collisions well above the electroweak scale, the collinear splitting mechanism of the electroweak gauge bosons becomes the dominant phenomena via the initial state radiation and the final state showering.

New parton distributions for collider physics [PDF]
, 2010 We extract new parton distribution functions (PDFs) of the proton by global analysis of hard scattering data in the general-mass framework of perturbative quantum chromodynamics.
