A relativistic many-body calculation for an effective QCD Hamiltonians reported for exotic and charmed hybrid mesons. The nonexotic J(PC) = 1(--) charmonium spectrum now resolves the anonymous overpopulation of observed J/psi states. The exotic [...]![]()

We represent QCD at the hadronic scale by means of an effective Hamiltonian, H, formulated in the Coulomb gauge. As in the Nambu-Jona-Lasinio model, chiral symmetry is explicitly broken, however our approach is renormalizable and also includes c[...]![]()

We show how to fix the renormalization scale for hard scattering exclusive processes such as deeply virtual meson electroproduction by applying the BLM prescription to the imaginary part of the scattering amplitude and employing a fixed-t disper[...]![]()

Dobado González, Antonio ; Llanes Estrada, Felipe José ; Sanz Cillero, Juan José | Springer | 2018-03-26We examine the production of W h and Zh pairs at the LHC in the context of a Strongly Interacting Symmetry Breaking Sector of the Standard Model. Our description is based on a non-linear Higgs Effective Theory, including only the Standard Model [...]![]()

We construct a model for the quark-gluon vertex of Landau gauge QCD. This is of twofold interest: on the one hand the quark-gluon interaction is at the heart of quark confinement, on the other hand it is a central element in hadron phenomenology[...]![]()

Carrasco Millán, Pedro ; García-Ferrero, M. Ángeles ; Llanes Estrada, Felipe José ; Porras Riojano, Ana ; Sánchez García, Esteban M. | Elsevier Science BV | 2018-05We deploy Shannon’s information entropy to the distribution of branching fractions in a particle decay. This serves to quantify how important a given new reported decay channel is, from the point of view of the information that it adds to the al[...]![]()

Llanes Estrada, Felipe José ; Dobado González, Antonio ; Torres Rincón, Juan M. | American Physical Society | 2013-09-12We explore the viscosities of a photon gas by means of the Euler-Heisenberg effective theory and quantum electrodynamics at zero electron chemical potential. We find parametric estimates that show a very large shear viscosity and an extremely sm[...]![]()

Manuel, Cristina ; Dobado González, Antonio ; Llanes Estrada, Felipe José | Int School Advanced Studies | 2005-09We compute the mean free path and shear viscosity in the color-flavor locked (CFL) phase of dense quark matter at low temperature T, when the contributions of mesons, quarks and gluons to the transport coefficients are Boltzmann suppressed. CFL [...]![]()

We study the collisional aspects of jet quenching in a high-energy nuclear collision, especially in the final state pion gas. The jet has a large energy, and acquires momentum transverse to its axis more effectively by multiple soft collisions t[...]![]()

García Fernández, Guillermo ; Guerrero Rojas, Jesús ; Llanes Estrada, Felipe José | Elsevier | 2017-02The gauge symmetry of the Standard Model is SU(3)_(c) x SU(2)_(L) x U(1)_(Y) for unknown reasons. One aspect that can be addressed is the low dimensionality of all its subgroups. Why not much larger groups like SU(7), or for that matter, SP(38) [...]![]()

García Fernández, Guillermo ; Guerrero Rojas, Jesús ; Llanes Estrada, Felipe José | Elsevier | 2019-12We point out an error in our previous work, that affects the claims made for the special Lie groups and for the SO(N-c) groups of lowest dimension, which are therefore retracted. Our earlier results stand for larger-dimension SO(N-c), as well as[...]![]()

Llanes Estrada, Felipe José ; Cabrera, Daniel ; Luciano M., Abreu ; Bratkovskaya, Elena ; Ramos, Angels ; Torres Rincón, Juan M. | IOP publishing ltd | 2014We 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 strangeness sector, we discu[...]![]()

Delgado López, Rafael ; Dobado González, Antonio ; Llanes Estrada, Felipe José | American Institute of Physics (AIP) | 2016The apparent finding of a 125 GeV light Higgs boson would close the minimal Standard Model (SM), that is weakly interacting. This is an exceptional feature not generally true if new physics exists beyond the mass gap found at the LHC up to 700 G[...]![]()

Dobado González, Antonio ; Delgado López, Rafael ; Llanes Estrada, Felipe José | American Institute of Physics | 2014The apparent finding of a 125-GeV light Higgs boson closes unitarity of the minimal Standard Model (SM), that is weakly interacting: this is an exceptional feature not generally true if new physics exists beyond the mass gap found at the LHC up [...]
