Noether and topological currents equivalence and soliton/particle correspondence in affine sl(2)((1)) Toda theory coupled to matter
(Elsevier B.V., 2001-02-26)
A submodel of the so-called conformal affine Toda model coupled to the matter field (CATM) is defined such that its real Lagrangian has a positive-definite kinetic term for the Toda field and a usual kinetic term for the ...
Extended 2D generalized dilaton gravity theories
(Iop Publishing Ltd, 2008-09-07)
We show that an anomaly-free description of matter in (1+1) dimensions requires a deformation of the 2D relativity principle, which introduces a non-trivial centre in the 2D Poincare algebra. Then we work out the reduced ...
SPH simulations of clumps formation by dissipative collisions of molecular clouds - II. Magnetic case
(Edp Sciences S A, 2001-12-01)
We performed computer simulations of interstellar cloud-cloud collisions using the three-dimensional smoothed particle magnetohydrodynamics method. In order to study the role of the magnetic field on the process of ...
Study of the discovery potential of light custodians in a clean decay channel at the LHC
(Iop Publishing Ltd, 2009-08-01)
Models of warped extra dimensions with custodial symmetry usually predict the existence of a light Kaluza-Klein fermion arising as a partner of the right-handed top quark, sometimes called light custodians which we will ...
Extension of the Nambu-Jona-Lasinio model predictions at high densities and temperatures using an implicit regularization scheme
(Amer Physical Soc, 2008-06-01)
Traditional cutoff regularization schemes of the Nambu-Jona-Lasinio model limit the applicability of the model to energy-momentum scales much below the value of the regularizing cutoff. In particular, the model cannot be ...
Black hole partition function using the hybrid formalism of superstrings
(Amer Physical Soc, 2011-07-20)
The IIA superstring partition function ZIIA, on a Euclidean AdS(2) x S(2) x CY(3) computes the modified elliptic genus Z(BH) of the associated black hole. The hybrid formalism of superstrings on AdS(2) x S(2), defined as ...
Cubic interactions and quantum criticality in dimerized antiferromagnets
(Amer Physical Soc, 2011-05-06)
In certain Mott-insulating dimerized antiferromagnets, triplet excitations of the paramagnetic phase display both three-particle and four-particle interactions. When such a magnet undergoes a quantum phase transition into ...
Is the LHC observing the pseudoscalar state of a two-Higgs-doublet model?
(Amer Physical Soc, 2012-05-21)
The ATLAS and CMS collaborations have recently shown data suggesting the presence of a Higgs boson in the vicinity of 125 GeV. We show that a two-Higgs-doublet model spectrum, with the pseudoscalar state being the lightest, ...
Voltage-composition profile and synchrotron X-ray structural analysis of low and high temperature LixCoO2 host material
(Amer Chemical Soc, 2008-09-18)
In the present work, the intercalation of lithium ions in the LixCoO2 host material was investigated by means of the discharge curves and voltage-composition profile with the main goal of establishing a close correlation ...
Structure study of Bi4Ti3O12 produced via mechanochemically assisted synthesis
(Pergamon-Elsevier B.V. Ltd, 2008-07-01)
Nanosized bismuth titanate was prepared via high-energy ball milling process through mechanically assisted synthesis directly from their oxide mixture of Bi2O3 and TiO2. Only Bi4Ti3O12 phase was formed after 3 h of milling ...
