Electromagnetic form factors of vector mesons in Einstein-dilaton holographic QCD
Alfonso Ballon-Bayona, Tobias Frederico, Luis A. H. Mamani +2
We investigate the electromagnetic form factors of the meson family within a holographic QCD framework based on Einstein-dilaton gravity with confining backgrounds. We obtain t…
Chiral transition and meson melting within improved holographic soft wall models
Alfonso Ballon-Bayona, Sean Bartz, Luis A. H. Mamani +1
We describe the chiral transition for the quark condensate and the melting of scalar and vector mesons in two-flavor holographic QCD. This is done by extending the improved hologra…
Nucleons and vector mesons in a confining holographic QCD model
Alfonso Ballon-Bayona, Adão S. da Silva Junior
We present a simple holographic QCD model that provides a unified description of vector mesons and nucleons in a confining background based on Einstein-dilaton gravity. For the con…
A dynamical holographic QCD model for spontaneous chiral symmetry breaking and confinement
Alfonso Ballon-Bayona, Tobias Frederico, Luis A. H. Mamani +1
In this paper, we present a holographic realization of spontaneous chiral symmetry breaking and confinement. The latter is realized by building a solution of 5d Einstein-dilaton gr…
Spontaneous chiral symmetry breaking in holographic soft wall models
Alfonso Ballon-Bayona, Luis A. H. Mamani, Diego M. Rodrigues
We investigate non-linear extensions of the holographic soft wall model proposed by Karch, Katz, Son and Stephanov [1] including non-minimal couplings in the five-dimensional actio…
Nonlinear realization of chiral symmetry breaking in holographic soft wall models
Alfonso Ballon-Bayona, Luis A. H. Mamani
We investigate nonlinear extensions of the holographic soft wall model proposed by Karch, Katz, Son and Stephanov \cite{Karch:2006pv} with a positive quadratic dilaton. We consider…
Unity of pomerons from gauge/string duality
Alfonso Ballon-Bayona, Robert Carcasses Quevedo, Miguel S. Costa
We develop a formalism where the hard and soft pomeron contributions to high energy scattering arise as leading Regge poles of a single kernel in holographic QCD. The kernel is obt…
Strong couplings and form factors of charmed mesons in holographic QCD
Alfonso Ballon-Bayona, Gastao Krein, Carlisson Miller
We extend the two-flavor hard-wall holographic model of Erlich, Katz, Son and Stephanov [Phys.\ Rev.\ Lett.\ {\bf 95}, 261602 (2005)] to four flavors to incorporate strange and cha…
Soft Pomeron in Holographic QCD
Alfonso Ballon-Bayona, Robert Carcassés Quevedo, Miguel S. Costa +1
We study the graviton Regge trajectory in Holographic QCD as a model for high energy scattering processes dominated by soft pomeron exchange. This is done by considering spin J fie…
Decay constants of the pion and its excitations in holographic QCD
Alfonso Ballon-Bayona, Gastao Krein, Carlisson Miller
We investigate the leptonic decay constants of the pion and its excitations with a 5-d holographic model for quantum chromodynamics. We prove numerically that the leptonic decay co…
Production of negative parity baryons in the holographic Sakai-Sugimoto model
Alfonso Ballon-Bayona, Henrique Boschi-Filho, Nelson R. F. Braga +2
We extend our investigation of resonance production in the Sakai-Sugimoto model to the case of negative parity baryon resonances. Using holographic techniques we extract the genera…
