Impacts of Precipitation Variability on Carbon Flux Dynamics of Global Semi-Arid Savannas. [PDF]

open access: yesGlob Chang Biol
Semi‐arid ecosystems contribute most to the variability of the land carbon sink. They are water‐limited and therefore increased precipitation variability due to climate change has strong effects on their carbon cycle. We investigate the effects of precipitation amount, frequency, intensity and dry spell length on carbon fluxes of global semi‐arid ...

Off-shell generalized parton distributions and form factors of the pion

open access: yesPhysics Letters B, 2023
Off-shell effects in generalized parton distributions (GPDs) of the pion, appearing, e.g., in the Sullivan process, are considered. Due to the lack of crossing symmetry, the moments of GPDs involve also odd powers of the skewness (longitudinal momentum ...

Pion generalized parton distributions and light-front wave functions in the Nambu–Jona-Lasinio model

open access: yesNuclear 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

ρ meson GPDs and IPDs with a light-front constituent quark model [PDF]

open access: yesEPJ Web of Conferences, 2019
We investigate the ρ meson unpolarized Generalized Parton Distributions based on a Light-Front Constituent Quark Model. Moreover, by employing a Gaussian form wave packet, we apply the obtained generalized parton distributions to get the Impact Parameter

Exclusive double quarkonium production and generalized TMDs of gluons

open access: yesPhysics Letters B, 2022
Being the “mother distributions” of all types of two-parton correlation functions, generalized transverse momentum dependent parton distributions (GTMDs) have attracted a lot of attention over the last years.

T-odd generalized and quasi transverse momentum dependent parton distribution in a scalar spectator model

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Generalized transverse momentum dependent parton distributions (GTMDs), as mother funtions of transverse momentum dependent parton distributions (TMDs) and generalized parton distributions (GPDs), encode the most general parton structure of hadrons.

QCD factorization of quasi generalized quark distributions

open access: yesJournal of High Energy Physics, 2022
We study the factorization of quasi generalized quark distributions with twist-2 generalized parton distributions. We use an approach which is different than that used in literature.

Covariant extension of the GPD overlap representation at low Fock states

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We present a novel approach to compute generalized parton distributions within the lightfront wave function overlap framework. We show how to systematically extend generalized parton distributions computed within the DGLAP region to the ERBL one ...

The multidimensional nucleon structure

open access: yesEPJ Web of Conferences, 2016
We discuss different kinds of parton distributions, which allow one to obtain a multidimensional picture of the internal structure of the nucleon.

Hard exclusive reactions and generalized parton distributions

open access: yesEPJ Web of Conferences, 2015
The recently developed formalism of Generalized Parton Distributions (GPDs) allows connecting the experimental information of hard exclusive reactions to the spin contribution and even to the angular momentum contribution of quarks in the nucleon.
