Skyrmion approach to finite density and temperature
We review an approach, developed over the past few years, to describe hadronic matter at finite density and temperature, whose underlying theoretical framework is the Skyrme model, an effective lowExpand
The scalar glueball
We analyze several scenarios for a scalar glueball using arguments based on sum rules, spectral decomposition, the 1 Nc approximation, the scales of the strong interaction and the topology of theExpand
Double parton correlations in constituent quark models
We thank Markus Diehl for fruitful comments. S. S. thanks Livio Fano for useful discussions. This work was supported in part by the Research Infrastructure Integrating Activity Study of StronglyExpand
New anomalous trajectory in Regge theory
We show that a new Regge trajectory with ${\ensuremath{\alpha}}_{{f}_{1}}(0)\ensuremath{\approx}1$ and a slope ${\ensuremath{\alpha}}_{{f}_{1}}^{\ensuremath{'}}(0)\ensuremath{\approx}0$ explains theExpand
Generalized parton distributions of the pion in a Bethe-Salpeter approach
Abstract.We calculate generalized parton distribution functions in a field theoretic formalism using a covariant Bethe-Salpeter approach for the determination of the bound-state wave function. WeExpand
A Unified Approach to High Density: Pion Fluctuations in Skyrmion Matter
Abstract As the first in a series of systematic work on dense hadronic matter, we study the properties of the pion in dense medium using Skyrme's effective Lagrangian as a unified theory of theExpand
Monopolium production from photon fusion at the Large Hadron Collider
Magnetic monopoles have attracted the attention of physicists since the founding of the electromagnetic theory. Their search has been a constant endeavor which was intensified when Dirac establishedExpand
$\eta-\eta^\prime$ Mixing in the Flavor Basis and Large N
The mass matrix for $\eta-\eta^\prime$ is derived in the flavor basis at ${\cal O}(p^4)$ of the chiral Lagrangian using the large $N$ approximation. Under certain assumptions, the mixing angleExpand
Mechanism for the double-spin asymmetry in electromagnetic ρ production at HERMES
We calculate the contribution of meson and pomeron exchanges to the double-spin asymmetry in $\rho$-meson electromagnetic production at HERMES energies. We show that the observed double-spinExpand
Double parton correlations and constituent quark models: a light front approach to the valence sector
A bstractAn explicit evaluation of the double parton distribution functions (dPDFs), within a relativistic Light-Front approach to constituent quark models, is presented. dPDFs encode information onExpand
