The canonical structure of higher dimensional pure Chern-Simons theories is analyzed. It is shown that these theories have generically a nonvanishing number of local degrees of freedom, even though they are obtained by means of a topological con[...]texto impreso
Dobado González, Antonio ; Llanes Estrada, Felipe José ; Oller, Jose Antonio | Amer Physical Soc | 2012-01-20In general relativity, there is a maximum mass allowed for neutron stars that, if exceeded, entails collapse into a black hole. Its precise value depends on details of the nuclear matter equation of state, a subject where much progress has been [...]texto impreso
Krupa, K. ; Lange, E. ; Blanco Ramos, Francisco ; Barbosa, A. S. ; Pastega,, D. F. ; Sanchez, S. d’A. ; Bettega, M. H. F. ; García Jurado, G. | Amer Physical Soc | 2018-04-10We report on a combination of experimental and theoretical investigations into the elastic differential cross sections (DCSs) and integral cross sections for electron interactions with dichloromethane, CH?Cl?, in the incident electron energy ove[...]texto impreso
The experimental results obtained in the last few years on kaon decays (K ? 2 ? and, above all, Ke4 decays) allow a reliable, model-independent determination of low energy ? ? scattering in the S0 wave. Using them and, eventually, other sets of[...]texto impreso
Ferroelectric field-effect doping has emerged as a powerful approach to manipulate the ground state of correlated oxides, opening the door to a different class of field-effect devices. However, this potential is not fully exploited so far, sinc[...]texto impreso
The beta-decay of Zn-81 to the neutron magic N = 50 nucleus Ga-81, with only three valence protons with respect to Ni-78, was investigated. The study was performed at the ISOLDE facility at CERN by means of gamma spectroscopy. The 81Zn half-life[...]texto impreso
Fraile Prieto, Luis Mario ; Vedia Fernández, María Victoria ; Ibáñez García, Paula Beatriz ; Paziy, Vadym ; Pérez Liva, Mailyn ; Picado, E. ; Vidal, M. | Amer Physical Soc | 2016-04-04The levels in Sn-129 populated from the beta(-) decay of In-129 isomers were investigated at the ISOLDE facility of CERN using the newly commissioned ISOLDE Decay Station (IDS). The lowest 1/2(+) state and the 3/2(+) ground state in 129Sn are ex[...]texto impreso
In scalar-field dark matter scenarios, a scalar-field soliton could form at the center of galactic halos, around the supermassive black holes that sit at the center of galaxies. Focusing on the large scalar-mass limit, where the soliton is forme[...]texto impreso
Finite-temperature corrections to the effective potential and the energy-momentum tensor of a scalar field are computed in a perturbed Minkoswki spacetime. We consider the explicit mode decomposition of the field in the perturbed geometry and ob[...]texto impreso
Fraile Prieto, Luis Mario ; Gallardo, M. C. ; Vedia Fernández, María Victoria ; otros, ... | Amer Physical Soc | 2018-10-03The C-12(alpha,gamma)O-16 reaction plays a central role in astrophysics, but its cross section at energies relevant for astrophysical applications is only poorly constrained by laboratory data. The reduced a width, gamma(11), of the bound 1(-) l[...]texto impreso
Ivanov, M. V. ; Vignote, J. R. ; Alvarez Rodríguez, R. ; Meucci, A. ; Giusti, C. ; Udías Moinelo, José Manuel | Amer Physical Soc | 2016-07-14Optical potentials provide critical input for calculations on a wide variety of nuclear reactions, in particular, for neutrino-nucleus reactions, which are of great interest in the light of the new neutrino oscillation experiments. We present th[...]texto impreso
We study the possible effects of classical gravitational backgrounds on the Higgs field through the modifications induced in the one-loop effective potential and the vacuum expectation value of the energymomentum tensor. We concentrate our study[...]texto impreso
Wormhole boundary conditions for the Wheeler-DeWitt equation can be derived from the path integral formulation. It is proposed that the wormhole wave function must be square integrable in the maximal analytic extension of minisuperspace. Quantum[...]texto impreso
Martin Benito, M. ; Garay Elizondo, Luis Javier ; Mena Marugán, Guillermo A. | Amer Physical Soc | 2008-10We quantize an inhomogeneous cosmological model using techniques that include polymeric quantization. More explicitly, we construct well-defined operators to represent the constraints and find the physical Hilbert space formed by their solutions[...]texto impreso
The Immirzi ambiguity arises in loop quantum gravity when geometric operators are represented in terms of different connections that are related by means of an extended Wick transform. We analyze the action of this transform in gravity coupled w[...]texto impreso
We consider models of scalar dark matter with a generic interaction potential and noncanonical kinetic terms of the K-essence type that are subleading with respect to the canonical term. We analyze the low-energy regime and derive, in the nonrel[...]texto impreso
Aranda, V. M. ; Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado, J. ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2015-05-26Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array (SD) of the Pierre Auger Observatory. We report here on searches through Auger data from 1 January 2004 until 20 June 2013. No neu[...]texto impreso
Garay Elizondo, Luis Javier ; Martin Benito, M. ; Mena Marugán, Guillermo A. | Amer Physical Soc | 2010-08-30The Gowdy cosmologies provide a suitable arena to further develop loop quantum cosmology, allowing the presence of inhomogeneities. For the particular case of Gowdy spacetimes with the spatial topology of a three-torus and a content of linearly [...]texto impreso
The Ernst equation for gravitational fields with a two-parameter isometry group is formulated as a vanishing-curvature condition on an SU(2) or SU(1,1) bundle, both in the elliptic and hyperbolic cases. Bäcklund transformations are introduced as[...]texto impreso
The inverse amplitude method is a powerful unitarization technique to enlarge the energy applicability region of effective Lagrangians. It has been widely used to describe resonances in hadronic physics, combined with chiral perturbation theory,[...]texto impreso
