Vacuum Properties of Mesons in a Linear Sigma Model with Vector Mesons and Global Chiral Invariance

, 2010
We present a two-flavour linear sigma model with global chiral symmetry and vector and axial-vector mesons. We calculate pion-pion scattering lengths and the decay widths of scalar, vector, and axial-vector mesons.

Zero temperature properties of mesons in a vector meson extended linear sigma model

EPJ Web of Conferences, 2011
A three flavor linear sigma model with vector and axial-vector mesons is discussed. Preliminary results concerning on the symmetry breaking pattern, the question of parameterization, as well as the resulting meson masses are presented.

Glueball enhancements in p(gamma,VV)p through vector meson dominance

, 2004
Double vector meson photoproduction, p(gamma, G -> VV)p, mediated by a scalar glueball G is investigated. Using vector meson dominance (VMD) and Regge/pomeron phenomenology, a measureable glueball enhancement is predicted in the invariant VV = rho rho ...

Vector meson production at HERA [PDF]

AIP Conference Proceedings, 2005
The diffractive production of vector mesons ep→eVMY, with VM=ρ0, ω, ϕ, J/ψ, ψ′ or ϒ and with Y being either the scattered proton or a low mass hadronic system, has been extensively investigated at HERA. HERA offers a unique opportunity to study the dependences of diffractive processes on different scales: the mass of the vector meson, mVM, the centre-

Recent ATLAS results in the field of meson physics

EPJ Web of Conferences, 2014
Recent results on flavor physics are presented, using data from the ATLAS detector. The ϓ(nS) and charmonium inclusive production cross sections are discussed. J/ψ production associated with a W vector boson is presented.

Dilepton production in proton-proton collisions at BEVALAC energies

, 2003
The dilepton production in elementary ${pp\to e^{+}e^{-}X}$ reactions at BEVALAC energies $T_{lab}=1\div 5$ GeV is investigated. The calculations include direct ${e^{+}e^{-}}$ decays of the vector mesons $\rho ^{0}$, $\omega $, and $\phi $, Dalitz decays

Vector mesons and (virtual) nuclear optics

Physics Letters B, 1974
Abstract Nuclear photoproduction and inelastic electron-nucleus scattering at high energies are investigated in the framework of a scaling model of electromagnetic interactions which has been recently proposed. No shadowing is predicted to take place for large q2. Our results are in agreement with the available experimental data.

Coupling vector and pseudoscalar mesons to study baryon resonances

, 2011
A study of meson-baryon systems with total strangeness -1 is made within a framework based on the chiral and hidden local symmetries. These systems consist of octet baryons, pseudoscalar and vector mesons.
