Limits on electroweak instanton-induced processes with multiple boson production

open access: yesJournal 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

open access: yesJournal 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

Operator product expansion of the non-local gluon condensate

open access: yesJournal 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,

Phenomenological Predictions for Deep-Inelastic Electron Scattering [PDF]

open access: yesPhysical 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.

Increasing the Magnetic Blocking Temperature of Single‐Molecule Magnets

open access: yesAngewandte 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 ...

The photon content of the proton

open access: yesJournal of High Energy Physics, 2017
The photon PDF of the proton is needed for precision comparisons of LHC cross sections with theoretical predictions. In a recent paper, we showed how the photon PDF could be determined in terms of the electromagnetic proton structure functions F 2 and F ...

Transverse-energy-energy correlations in deep inelastic scattering

open access: yesJournal 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

Pion-induced Drell-Yan processes within TMD factorization

open access: yesJournal of High Energy Physics, 2019
We extract the pion transverse momentum dependent (TMD) parton distribu- tion by fitting the pion-induced Drell-Yan process within the framework of TMD factoriza- tion.

TMD fragmentation functions at N3LO

open access: yesJournal of High Energy Physics, 2021
We compute the unpolarized quark and gluon transverse-momentum dependent fragmentation functions (TMDFFs) at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD.
