Low x_{bj} DIS, QCD and Generalized Vector Dominance

, 1999
We give a brief overview on the present status of Generalized Vector Dominance as appplied to vector-meson production and the total photoabsorption cross section in the region of small x_{bj}.

To VMD, or not to VMD, in the quark-gluon plasma [PDF]

, 1995
I review results on the shift of the $\rho$ meson mass at nonzero temperature in a gauged linear sigma model, under the assumption of strict vector meson dominance. (Based upon a talk presented at the International Workshop on "Chiral Dynamics in Hadrons

Weak Radiative Hyperon Decays and Vector Meson Dominance

, 1998
We study the question whether the phenomenologically successful VMD approach to weak radiative hyperon decays can be made consistent with Hara's theorem and still yield the pattern of asymmetries exhibited by experimental data.

Electromagnetic form factor of the pion in the space- and time-like regions within the front-form dynamics [PDF]

, 2003
The pion electromagnetic form factor is calculated in the space- and time-like regions from -10 $(GeV/c)^2$ up to 10 $(GeV/c)^2$, within a front-form model.

Vector Meson Dominance

, 2005
Historically vector-meson physics arose along two different paths to be reviewed in Sections 1 and 2. In Section 3, the phenomenological consequences will be discussed with an emphasis on those aspects of the subject matter relevant in present-day ...

K*-couplings for the antidecuplet excitation

, 2007
We estimate the coupling of the K* vector meson to the N-->Theta+ transition employing unitary symmetry, vector meson dominance, and results from the GRAAL Collaboration for eta photoproduction off the neutron.

Photon-3-Pion And Pion-2-Photon Form Factors From Dynamical Constituent Quarks

, 2001
We study the form factors of the low energy anomalous pion-2-photon and photon-3-pion processes in the nonlocal chiral quark model which incorporates the momentum dependence of the dynamical quark mass and realizes correctly the chiral symmetries.

Finite pion width effects on the rho--meson

, 2000
We study the influence of the finite damping width of pions on the in-medium properties of the rho-meson in an interacting meson gas model at finite temperature. Using vector dominance also implications on the resulting dilepton spectra from the decay of

Dilepton Production from Rho-Mesons in a Quark-Gluon Plasma

, 1999
Assuming that rho-mesons exist in a quark-gluon plasma close to the QCD phase transition, we calculate the dilepton production rate from quark-antiquark annihilation via a rho-meson state using Vector Meson Dominance.

Transport calculation of dilepton production at ultrarelativistic energies [PDF]

, 1999
Dilepton spectra are calculated within the microscopic transport model UrQMD and compared to data from the CERES experiment. The invariant mass spectra in the region 300 MeV < M < 600 MeV depend strongly on the mass dependence of the $\rho$ meson decay ...
