Non-perturbative structure of semi-inclusive deep-inelastic and Drell-Yan scattering at small transverse momentum

open access: yesJournal of High Energy Physics, 2020
We consider semi-inclusive deep inelastic scattering (SIDIS) and Drell-Yan events within transverse momentum dependent (TMD) factorization. Based on the simultaneous fit of multiple data points, we extract the unpolarized TMD distributions and the non ...

Extraction of partonic transverse momentum distributions from semi-inclusive deep-inelastic scattering, Drell-Yan and Z-boson production

open access: yesJournal of High Energy Physics, 2017
We present an extraction of unpolarized partonic transverse momentum distributions (TMDs) from a simultaneous fit of available data measured in semi-inclusive deep-inelastic scattering, Drell-Yan and Z boson production.

Mapping the kinematical regimes of semi-inclusive deep inelastic scattering

open access: yesJournal of High Energy Physics, 2019
We construct a language for identifying kinematical regions of transversely differential semi-inclusive deep inelastic scattering (SIDIS) cross sections with particular underlying partonic pictures, especially in the regions of moderate to low Q where ...

Semi-inclusive deep-inelastic scattering in Wandzura-Wilczek-type approximation

open access: yesJournal of High Energy Physics, 2019
We present the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed O 1 / Q 2 $$ \mathcal{O}\left(1/{Q}^2\right) $$ terms in the Wandzura-Wilczek-type approximation, which ...

The Drell-Yan process with pions and polarized nucleons

open access: yesJournal of High Energy Physics, 2021
The Drell-Yan process provides important information on the internal struc- ture of hadrons including transverse momentum dependent parton distribution functions (TMDs).

Quark-sector Lorentz violation in Z-boson production

open access: yesJournal of High Energy Physics, 2021
Quark-sector Lorentz violation is studied in the context of Drell-Yan dilepton production including effects from Z-boson exchange. We show the chiral nature of the weak interactions enables parity-violating and spin-dependent effects to be studied using ...

Multivalued Memory via Freezing of Super‐Hard Magnetic Domains in a Quasi 2D‐Magnet

open access: yesSmall Methods, Volume 7, Issue 11, November 16, 2023., 2023
The 2D‐Ising ferromagnet BaFe2(PO4)2, is affected below 15 K by the freezing of its magnetic domains due to giant magneto‐crystalline anisotropy and intrinsic pinning of the narrow domain walls. It results in a transition from a soft to a super‐hard magnet with record‐coercive force greater than 14 T, and allows for the writing, robust locking and ...

Kinematic distributions of the η c leptoproduction in association with light hadrons

open access: yesJournal of High Energy Physics, 2021
The η c meson leptoproduction is calculated within the nonrelativistic QCD framework for the first time. It is found that the colour-singlet channel, although suppressed by a factor of α s relative to the colour-octet ones, provides important ...

Advancing Our Understanding of Martian Proton Aurora Through a Coordinated Multi‐Model Comparison Campaign

open access: yesJournal of Geophysical Research: Space Physics, Volume 128, Issue 10, October 2023., 2023
Abstract Proton aurora are the most commonly observed yet least studied type of aurora at Mars. In order to better understand the physics and driving processes of Martian proton aurora, we undertake a multi‐model comparison campaign. We compare results from four different proton/hydrogen precipitation models with unique abilities to represent Martian ...

Soft corrections to inclusive deep-inelastic scattering at four loops and beyond

open access: yesJournal of High Energy Physics, 2020
We study the threshold corrections for inclusive deep-inelastic scattering (DIS) and their all-order resummation. Using recent results for the QCD form factor, related anomalous dimensions and Mellin moments of DIS structure functions at four loops we ...
