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…
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…
Melting of heavy vector mesons and quasinormal modes in a finite density plasma from holography
Luis A. H. Mamani, Defu Hou, Nelson R. F. Braga
In this work, we investigate the melting of charmonium states within a holographic QCD model in the context of Einstein-Maxwell-Dilaton (EMD) theory. In the dual field theory, the…
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…
