Heavy-flavor parton distributions without heavy-flavor matching prescriptions

Journal of High Energy Physics, 2018
We show that the well-known obstacle for working with the zero-mass variable flavor number scheme, namely, the omission of O1 $$ \mathcal{O}(1) $$ mass power corrections close to the conventional heavy flavor matching point (HFMP) μ b = m, can be easily ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).

Angularity in DIS at next-to-next-to-leading log accuracy

Journal of High Energy Physics, 2021
Angularity is a class of event-shape observables that can be measured in deep-inelastic scattering. With its continuous parameter a one can interpolate angularity between thrust and broadening and further access beyond the region.

BME Model: Forecasting Electricity Supply and Demand Curves Using Disentangled Prices and Volumes

Applied Stochastic Models in Business and Industry, Volume 41, Issue 4, July/August 2025.
ABSTRACT This paper introduces a novel modeling setup for forecasting day‐ahead electricity market demand and supply curves, seen as bid prices as a function of bid volumes. These curves are different for each different next‐day hour. The daily data structures on which these curves are assembled have very peculiar features, which make them very ...

Global extraction of partonic transverse momentum distributions from semi-inclusive deep inelastic scattering and Drell-Yan data [PDF]

, 2017
We discuss a first attempt at a global extraction of unpolarized partonic transverse momentum dependent (TMD) distributions and fragmentation functions from a simultaneous fit of data measured in semi-inclusive deep-inelastic scattering, Drell–Yan and Z ...

Statistical analysis of the azimuthal asymmetry in the J/𝜓 leptoproduction in unpolarized ep collisions

Journal of High Energy Physics, 2019
In this paper, we study the azimuthal asymmetry in the J/𝜓 leptoproduction in unpolarized ep collisions. There are two independent azimuthal asymmetry modulations, namely cos(𝜓) and cos (2 𝜓), where 𝜓 is the azimuthal angle of the lepton scattering plane

A Multiquark Approach to Excited Hadrons and Regge Trajectories

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
We propose a novel approach to construction of hadron spectroscopy. The case of light nonstrange mesons is considered. By assumption, all such mesons above 1 GeV appear due to creation of constituent quark‐antiquark pairs inside π or ρ(ω) mesons. These spin‐singlet or triplet pairs dictate the quantum numbers of formed resonance.
