- 9 March 2010
We present an analysis of the baryon-octet and -decuplet masses using covariant SU(3)-flavor chiral perturbation theory up to next-to-leading order. Besides the description of the physical masses we…

Vector meson-vector meson interaction in a hidden gauge unitary approach
The formalism developed recently to study vector meson-vector meson interaction, and applied to the case of {rho}{rho}, is extended to study the interaction of the nonet of vector mesons among…
Towards the discovery of new physics with lepton-universality ratios of b -> sll decays

Tests of lepton-universality as rate ratios in b → s(cid:96)(cid:96) transitions can be predicted very accurately in the Standard Model. The deficits with respect to expectations reported by the LHCb…

We have investigated the neutrino induced coherent pion production reaction at the energies of interest for recent experiments like K2K and MiniBooNE. The model includes pion, nucleon and the…
Masses, deformations and charge radii: Nuclear ground-state properties in the relativistic mean field model
We perform a systematic study of the ground-state properties of all the nuclei from the proton drip line to the neutron drip line throughout the periodic table employing the relativistic mean field…
Scattering lengths of Nambu-Goldstone bosons off $D$ mesons and dynamically generated heavy-light mesons

- Physics
- 18 September 2013
Recent lattice QCD simulations of the scattering lengths of Nambu-Goldstone bosons off the $D$ mesons are studied using unitary chiral perturbation theory. We show that the Lattice QCD data are…
