Radiaciones solares: tipos y efectos

2000-01-01

A review on solar radiation and its effect on skin has been made. Exposure to sunlight can have both beneficial and harmful effects on the human body, depending on the wavelenght and the frequency of exposure, the intensity of the sunlight and the sensitivity of the individual concerned. Solar radiation consists of a continuous spectrum of frequencies or wave lengths from the infrared through the visible light to the ultraviolet region and beyond.

Results are presented on a search for neutral heavy leptons that couple to muon neutrinos in high-energy neutrino-nucleon interactions (${E}_{\ensuremath{\nu}}$=30--230 GeV). No evidence for such particles is observed. We obtain upper limits on the coupling of neutral neavy leptons to ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ below Fermi strength in the mass range 0.25--14 GeV/${c}^{2}$.

Neutrino Production of Like-Sign Dimuons

1985-01-01

Neutrino interactions with two muons in the final state were studied using the Fermilab narrow band beam. A sample of 18 like sign dimuon events with momentum P/sub ..mu../ > 9 GeV/c yields a prompt signal of 8.1 +- 4.4 events and a rate of (1.4 +- 0.8) x 10/sup -4/ per single muon event. The kinematics of these events are compared with those of the non-prompt sources. 15 refs., 13 figs.

A search for inclusive muon-neutrino (${\ensuremath{\nu}}_{\ensuremath{\mu}}$) oscillations has been performed in the Fermilab narrow-band neutrino beam using two detectors running simultaneously at two distances from the neutrino source. The data show no evidence for a distance dependence of the neutrino flux and rule out oscillations of ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ into any other single type of neutrino for $30&lt;\ensuremath{\Delta}{m}^{2}&lt;1000$ ${\mathrm{eV}}^{2}$/${\mathit{c}}^{4}$ and ${sin}^{2}(2\ensuremath{\theta})&gt;0.02\ensuremath{-}0.20$.
