Multisolitons with vector mesons on the two-sphere
(Lancaster, 2014-08)
Recent studies have suggested a strong connection between the static solutions of the 3D Skyrme modeland those corresponding to its low-dimensional analog (baby-Skyrme model) on a two-sphere. We havefound almost identical ...
Strange and heavy mesons in hadronic matter
(2013)
We present selected results on the properties of strange and heavy-flavoured mesons in a hot and dense nuclear medium, with emphasis in selfconsistent coupled-channel approaches based on the chiral Lagrangian. In the ...
Cross section of pseudoscalar meson photoproduction within the ELA
(Elsevier Science, 2015-03)
We study the contributions of background and resonance terms to the total cross section of photoproduction of mesons off the free nucleon. The model we use is consistent and based on an effective Lagrangian approach (ELA) ...
Properties of vector and axial-vector mesons in a nonlocal SU(2) PNJL model
(American Physical Society, 2019-10-14)
We study the features of a SU(2) Polyakov-Nambu-Jona-Lasinio model that includes wave function renormalization and nonlocal vector interactions. Within this framework we analyze, among other properties, the masses, width, ...
Electromagnetic form factor of the pion in the space- and time-like regions within the front-form dynamics
(2004-02-12)
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. The dressed photon vertex where a photon decays in a quark-antiquark ...
Review of Hadrons in Medium
(Amer Inst Physics, 2016-01-01)
I review the present status in the theoretical and phenomenological understanding of hadron properties in strongly interacting matter. The topics covered are the EMC effect, nucleon structure functions in cold nuclear ...
Dispersive representation of the pion vector form factor in τ→ππν τ decays
(Springer, 2013-08)
We propose a dispersive representation of the charged pion vector form factor that is consistent with chiral symmetry and fulfills the constraints imposed by analyticity and unitarity. Unknown parameters are fitted to the ...
Strong couplings and form factors of charmed mesons in holographic QCD
(Amer Physical Soc, 2017-07-21)
We extend the two-flavor hard-wall holographic model of Erlich, Katz, Son, and Stephanov [Phys. Rev. Lett. 95, 261602 (2005)] to four flavors to incorporate strange and charm quarks. The model incorporates chiral and flavor ...
Pion electromagnetic form factor and Fock state components
(2006-12-01)
The pion electromagnetic form factor in the space- and time-like regions are for the first time analyzed within a light-front model, that allows one to address the fundamental issue of non-valence components of the pion ...
