1. New limits for the violation of the equivalence prinriple on solar neutrinos / Novos limites para violação do principio da equivalencia em neutrinos solares
In this work, we studied the model for the violation of the equivalence principle (VEP) on solar and reactor neutrinos. This model was already considered as a promising solution to the solar neutrino problem (SNP), but was abandoned because it wasn?t able to explain all the data with a single set of physical parameters. The mass- avor mixing model, together

2. Space isotropy and weak equivalence principle in a scalar theory of gravity
We consider a preferred-frame bimetric theory in which the scalar gravitational field both influences the metric and has direct dynamical effects. A modified version ("v2") is built, by assuming now a locally-isotropic dilation of physically measured distances, as compared with distances evaluated with the Euclidean space metric. The dynamical equations stay

3. Low Energy (Anti)atoms for Precision Tests of Basic Physics
Recent advances in techniques to manipulate and study, with high precision, atomic hydrogen, from one hand, and successful trapping schemes for positrons and antiprotons, from the other hand, have encouraged the pursuit of experiments to test CPT violation and the Weak Equivalence Principle (WEP) through the comparison of hydrogen and antihydrogen. A descrip

4. Exotic Solutions to the Solar Neutrino Anomaly
We analyze the status of the exotic solutions to the solar neutrino problem, i.e., those solutions based on new phenomena which are not the usual neutrino oscillations induced by masses and mixing. These solutions are based on different assumptions: a) resonant spin-flavor precession induced by non-vanishing neutrino magnetic moment, b) the existence of non-
