Property of recombination in polarized hadronic targets [PDF]
Physical 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]
Nuclear 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

On properties of the exotic hadrons from QCD sum rules
, 2016 We discuss the specific features of extracting properties of the exotic polyquark hadrons (tetraquarks, pentaquarks) compared to the usual hadrons by the QCD sum-rule approach. In the case of the ordinary hadrons, already the one-loop leading-order O(α0s)

Measuring hadron properties at finite temperature [PDF]
Physical 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 ...

Spectroscopy and lifetime of bottom and charm hadrons [PDF]
, 2000 There are several motivations for studying masses and lifetimes of the hadrons containing a heavy quark, either the bottom or the charm quark. First, the mass and the lifetime are fundamental properties of an elementary particle. Second, the spectroscopy

Gravitational transition form factors of N → ∆ via QCD light-cone sum rules
Journal of High Energy Physics, 2023 We present the first direct calculation on the gravitational form factors (GFFs) of the N → ∆ transition using an analytic method, the QCD light-cone sum rules. The matrix element of the quark part of the energy momentum tensor current sandwiched between

Hadronic properties of the photon [PDF]
EPJ 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 ...

A possible subthreshold pole in S 11 channel from πN Roy-Steiner equation analyses
Journal of High Energy Physics, 2022 The hyperbolic version of Roy-Steiner equation describing low energy πN scatterings, with larger analyticity domain in the complex s plane is solved. The numerical results on phase shifts of low partial waves are in agreement with that of Hoferichter et ...
