Novel Aspects of QCD in Leptoproduction [PDF]
, 2004 I review several topics in electroproduction which test fundamental aspects of QCD. These include the role of final-state interactions in producing diffractive leptoproduction processes, the shadowing of nuclear structure functions, and target-spin ...

Experimental Status of Exotic Mesons and the GlueX Experiment [PDF]
, 2006 One of the unanswered and most fundamental questions in physics regards the nature of the confinement mechanism of quarks and gluons in QCD. Exotic hybrid mesons manifest gluonic degrees of freedom and their spectroscopy will provide the data necessary ...

Journal of High Energy Physics, 2022 The Effective Field Theory (EFT) Lagrangian for a generic axion-like particle (ALP) has many free parameters, and leaves quite some freedom for the expected phenomenology.

NNLO Matrix-Element Corrections in VINCIA [PDF]
Proceedings of 16th International Symposium on Radiative Corrections: Applications of Quantum Field Theory to Phenomenology — PoS(RADCOR2023), 2023 We report on a new formalism for parton showers whose fixed-order expansion can be corrected through next-to-next-to-leading order (NNLO) in QCD. It is the first such formalism we are aware of that has no dependence on any auxiliary scales or external ...

Phenomenology of Λb→Λcτν¯τ$$ {\Lambda}_b\to {\Lambda}_c\tau {\overline{\nu}}_{\tau } $$ using lattice QCD calculations [PDF]
, 2017 A bstractIn a recent paper we studied the effect of new-physics operators with different Lorentz structures on the semileptonic Λb→Λcτν¯τ$$ {\Lambda}_b\to {\Lambda}_c\tau {\overline{\nu}}_{\tau } $$ decay. This decay is of interest in light of the R(D(*))

Theoretical tools for neutrino scattering: interplay between lattice QCD, EFTs, nuclear physics, phenomenology, and neutrino event generators [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2022 Maximizing the discovery potential of increasingly precise neutrino experiments will require an improved theoretical understanding of neutrino-nucleus cross sections over a wide range of energies.

Quark formation and phenomenology in binary neutron-star mergers using V-QCD [PDF]
SciPost Physics, 2022 Using full 3+1 dimensional general-relativistic hydrodynamic simulations of equal- and unequal-mass neutron-star binaries with properties that are consistent with those inferred from the inspiral of GW170817, we perform a detailed study of the quark ...

The high-energy limit of perturbative QCD: Theory and phenomenology [PDF]
EPJ Web of Conferences, 2022 After a brief introduction of formal and phenomenological progresses in the study of the high-energy limit of perturbative QCD, we present arguments supporting the statement that the inclusive emission of Higgs bosons or heavy-flavored hadrons acts as ...

Light-front approach to axial-vector quarkonium γ * γ * form factors
Journal of High Energy Physics, 2022 In this work, we perform a detailed study of transition form factors for axial- vector meson production via the two-photon fusion process γ * γ * → 1++, with space-like virtual photons in the initial state and a P-wave axial-vector quarkonium in the ...

On the polarization of the non-prompt contribution to inclusive J/ψ production in pp collisions
Journal of High Energy Physics, 2022 Of the J/ψ mesons (inclusively) produced in pp collisions, a big fraction results from B decays, increasing with transverse momentum and exceeding 50% for p T > 20 GeV.
