Comments on the Riemann conjecture and index theory on Cantorian fractal space-time

Carlos Castro, Jorge Mahecha

An heuristic proof of the Riemman conjecture is proposed. It is based on the old idea of Polya-Hilbert. A discrete/fractal derivative self adjoint operator whose spectrum may conta…

Bilinear R-parity Violation and Small Neutrino Masses: a Self-consistent Framework

J. M. Mira, E. Nardi, D. A. Restrepo +1

We study extensions of supersymmetric models without R-parity which include an anomalous U(1)_H horizontal symmetry. Bilinear R-parity violating terms induce a neutrino mass at tre…

Pulsar acceleration by asymmetric emission of sterile neutrinos

Enrico Nardi, Jorge I. Zuluaga

A convincing explanation for the observed pulsar large peculiar velocities is still missing. We argue that any viable particle physics solution would most likely involve the resona…

Interband absorption and luminescence in small quantum dots under strong magnetic fields

Augusto Gonzalez, Eduardo Menendez-Proupin

Interband absorption and luminescence of quasi-two-dimensional, circularly symmetric, N_e electron quantum dots are studied at high magnetic fields, 8<B<60 T, and low temperatures,…

Effects of a general set of interactions on neutrino propagation in matter

E. Nardi

This talk is based on the article hep-ph/9903517 written in collaboration with Sven Bergmann and Yuval Grossman. An analysis of the effective potential for neutrino propagation in…
