, 2022 We discuss the determination of the parton substructure of hadrons by casting it as a peculiar form of pattern recognition problem in which the pattern is a probability distribution, and we present the way this problem has been tackled and solved. Specifically, we review the NNPDF approach to PDF determination, which is based on the combination of a ...

A Monte-Carlo simulation of double parton scattering
Journal of High Energy Physics, 2019 In this work, a new Monte-Carlo simulation of double parton scattering (DPS) at parton level is presented. The simulation is based on the QCD framework developed recently by M. Diehl, J. R. Gaunt and K. Schönwald. With this framework, the dynamics of the

, 2004 I discuss our current understanding of parton distributions. I begin with the underlying theoretical framework, and the way in which different data sets constrain different partons, highlighting recent developments.

On the intrinsic bottom content of the nucleon and its impact on heavy new physics at the LHC [PDF]
, 2015 Heavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most analyses rely on the assumption that the charm and bottom PDFs are generated perturbatively by gluon splitting and do not ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Lipid droplets (LDs) serve as the primary storage site for neutral lipids in plant cells, with growing evidence supporting many additional biological roles, such as in lipid homeostasis, signalling, trafficking, inflammatory responses and inter‐organelle communication.

Physics Letters B, 1979 Abstract We formulate an evolution equation for the generating functional of parton distributions. It permits a detailed study of the branching process. Several numerical examples are given, and the relevance for jet phenomenology discussed.

Taming the Energy Rise of the Total Proton-Proton Cross-Section
Universe, 2019 Steep rise of parton densities in the limit of small parton momentum fraction x poses a challenge for describing the observed energy-dependence of the total and inelastic proton-proton cross sections σ p p tot / inel : considering a ...

Double D-meson production in proton-proton and proton-lead collisions at the LHC
Physics Letters B, 2020 We consider the simultaneous production of two heavy-flavoured hadrons – particularly D mesons – at the LHC. We base our calculations on collinearly factorized QCD at next-to-leading order, using the contemporary parton distribution functions and D-meson

Unintegrated Double Parton Distributions - a Summary
, 2016 We present main elements of the construction of unintegrated double parton distribution functions which depend on transverse momenta of partons. We follow the method proposed by Kimber, Martin and Ryskin for a construction of unintegrated single parton ...

Production of Z bosons in the parton branching method [PDF]
Physical Review D, 2019 Transverse Momentum Dependent (TMD) parton distributions obtained from the Parton Branching (PB) method are combined with next-to-leading-order (NLO) calculations of Drell-Yan (DY) production.
