Neutrino Magnetic Moment Upper Bound From Solar Neutrino Observations
Joao Pulido, Ana M. Mourao
Using the data from SuperKamiokande, Kamiokande and Homestake solar neutrino experiments we derive an upper bound on the magnetic moment of the neutrino and find $μ_{ν_e}\leq(2.2-2…
Borexino as a test of solar matter density fluctuations
H. Nunokawa, A. Rossi, V. Semikoz +1
This talk summarizes some results of our recent work focusing on the possibility to test solar matter density fluctuations by the future Borexino experiment.
Bounds on sterile neutrino mixing for cosmologically interesting mass range
H. Nunokawa, J. T. Peltoniemi, A. Rossi +1
This talk summarizes our recent work which studied the impact of resonant and ( is a sterile neutrino) conversions on supernova physics, under…
Characteristic functions and process identification by neural networks
Joaquim A. Dente, R. Vilela Mendes
Principal component analysis (PCA) algorithms use neural networks to extract the eigenvectors of the correlation matrix from the data. However, if the process is non-Gaussian, PCA…
Feigenbaum networks
Rui Carvalho, R. Vilela Mendes, Joao Seixas
We study dynamical systems composed of a set of linearly coupled quadratic maps which, if uncoupled, would be on the Feigenbaum accumulation point. For two units we prove the exist…
Possible Tomography of the Sun's Magnetic Field with Solar Neutrinos
Joao Pulido
The data from solar neutrino experiments together with standard solar model predictions are used in order to derive the possible profile of the magnetic field inside the Sun, assum…
