nNNPDF2.0: quark flavor separation in nuclei from LHC data
Journal of High Energy Physics, 2020 We present a model-independent determination of the nuclear parton distribution functions (nPDFs) using machine learning methods and Monte Carlo techniques based on the NNPDF framework.

HERA Physics Beyond the Standard Model [PDF]
, 1999 The prospects of physics beyond the standard model in deep inelastic scattering are reviewed, emphasizing some scenarios which attained attention after the observation of an excess of events with large momentum transfer at HERA.Comment: 8 pages, LaTeX ...

Phenomenological Predictions for Deep-Inelastic Electron Scattering [PDF]
Physical Review D, 1971 With preliminary information from colliding beams relative to the coupling of photons with "high-mass" hadron states, we have extended the 1960 Drell model for photons interacting with nucleons to estimate off-the-mass-shell photon cross sections.

Neutrino telescopes as QCD microscopes
Journal of High Energy Physics, 2019 We present state-of-the-art predictions for the ultra-high energy (UHE) neutrino-nucleus cross-sections in charged- and neutral-current scattering. The calculation is performed in the framework of collinear factorisation at NNLO, extended to include the ...

Operator product expansion of the non-local gluon condensate
Journal of High Energy Physics, 2021 We consider the short-distance expansion of the product of two gluon field strength tensors connected by a straight-line-ordered Wilson line. The vacuum expectation value of this nonlocal operator is a common object in studies of the QCD vacuum structure,

Increasing the Magnetic Blocking Temperature of Single‐Molecule Magnets
Angewandte Chemie, Volume 136, Issue 2, January 8, 2024.Despite three decades of intensive investigation of single‐molecule magnets (SMMs) there are still unexplored roads towards increasing their magnetization blocking temperature. In this Review, after short overview of key SMM compounds, the basic strategies for further enhancement of SMM performance for mononuclear and polynuclear complexes are ...

Limits on electroweak instanton-induced processes with multiple boson production
Journal of High Energy Physics, 2018 Recently, the CMS collaboration has reported their search for electroweak instanton-like processes with anomalous B + L violation assuming multi-fermion but zero-boson final states. On the other hand, many theoretical studies suggest that anomalous B + L

Quarkonium TMD fragmentation functions in NRQCD
Journal of High Energy Physics, 2020 We study the transverse-momentum spectrum of quarkonium production from single light-parton fragmentation mechanism. In the case of semi-inclusive deep inelastic scattering, we observe that there are two possible initiating processes, namely photon-gluon

Transverse-energy-energy correlations in deep inelastic scattering
Journal of High Energy Physics, 2020 Event shape observables have been widely used for precision QCD studies at various lepton and hadron colliders. We present the most accurate calculation of the transverse-energy-energy correlation event shape variable in deep-inelastic scattering. In the

Theoretical aspects of high--Q^2 deep inelastic scattering [PDF]
, 1999 We present an overview of the theory of high--Q^2 deep inelastic scattering. We focus in particular on the theoretical uncertainties in the predictions for neutral and charged current cross sections obtained by extrapolating from lower Q^2.Comment: 10 ...
