Property of recombination in polarized hadronic targets [PDF]

open access: yesPhysical Review D, 1994
The triple gluon-ladder vertex is shown to project the outgoing gluon in either polarization state with equal probability up to the leading double-ln(x)ln($Q^2$) approximation. This implies that the $Q^2$-evolution of $ΔG (x, Q^2)$ is free from recombination effects to this level of approximation.

In-medium Hadrons – Properties, Interaction and Formation [PDF]

open access: yesNuclear Physics A, 2007
In this talk various aspects of in-medium behavior of hadrons are discussed with an emphasis on observable effects. Examples for theoretical predictions of in-medium spectral functions are given and the importance of resonance-hole excitations is stressed. It is also stressed that final state interactions can have a major effect on observables and thus

Perturbative calculations of gravitational form factors at large momentum transfer

open access: yesJournal of High Energy Physics, 2022
We perform a perturbative QCD analysis of the gravitational form factors (GFFs) of nucleon at large momentum transfer. We derive the explicit factorization formula of the GFFs in terms of twist-3 and twist-4 light-cone distribution amplitudes of nucleon.

Hadronic vacuum polarization and the MUonE proposal

open access: yesJournal of High Energy Physics, 2022
The MUonE proposal at the CERN SPS consists in extracting the value of the hadronic vacuum polarization self-energy function (HVP) from its contribution to the differential cross-section of elastic muon-electron scattering.

Measuring hadron properties at finite temperature [PDF]

open access: yesPhysical Review C, 1995
We estimate the numbers and mass spectra of observed lepton and kaon pairs produced from $ϕ$ meson decays in the central rapidity region of an Au+Au collision at lab energy 11.6 GeV/nucleon. The following effects are considered: possible mass shifts, thermal broadening due to collisions with hadronic resonances, and superheating of the resonance gas ...

Hadronic properties of the photon [PDF]

open access: yesEPJ Web of Conferences, 2019
Currently it is no doubt that high energy photons (real or virtual) have a hadronic component leading to photon shadowing in its interaction with nuclei. We shortly consider the difficulties appeared in the models like vector dominance model (VDM) and stress that these problems can be solved in a color dipole model inspired by Quantum Chromodynamics ...

Next-to-leading-power kinematic corrections to DVCS: a scalar target

open access: yesJournal of High Energy Physics, 2023
Using the recent results on the contributions of descendants of the leading twist operators to the operator product expansion of two electromagnetic currents we derive explicit expressions for the kinematic finite-t and target mass corrections to the ...
