Constraining non-standard interactions in nu(e) - e or anti-nu(e) - e scattering
2006
We present a new analysis of non-universal and flavor changing non-standard neutrino interactions (NSI) in \nu_e e or \bar{\nu}_e e scattering. Our global analysis of these process includes all relevant experiments, such as the most recent MUNU measurement from reactor neutrinos, both in the context of the Standard Model as well as extensions where NSI are present. We also compare our constraints on non-universal and flavor changing NSI with results from previous analyses. We stress the importance of combining neutrino and anti-neutrino data in the resulting constraints on electroweak paramaters, and the important role that future low energy solar neutrino experiments can play in improving …

Spherical harmonic moments are well-suited for capturing anisotropy at any scale in the flux of cosmic rays. An unambiguous measurement of the full set of spherical harmonic coefficients requires full-sky coverage. This can be achieved by combining data from observatories located in both the northern and southern hemispheres. To this end, a joint analysis using data recorded at the Telescope Array and the Pierre Auger Observatory above 1019 eV is presented in this work. The resulting multipolar expansion of the flux of cosmic rays allows us to perform a series of anisotropy searches, and in particular to report on the angular power spectrum of cosmic rays above 1019 eV.
