Evidence of the $K^+\to\mu^+\nu\bar\nu\nu$ decay was searched for using E949 experimental data with an exposure of $1.70\times 10^{12}$ stopped kaons. The data sample is dominated by the backgrond process $K^+\to\mu^+\nu_\mu\gamma$. An upper limit on

Search for heavy neutrinos in $K^+\to\mu^+\nu_H$ decays

Publikováno v: Phys. Rev. D 91, 052001 (2015)

Evidence of a heavy neutrino, $\nu_H$, in the $K^+\to\mu^+\nu_H$ decays was sought using the E949 experimental data with an exposure of $1.70\times 10^{12}$ stopped kaons. With the major background from the radiative $K^+\to\mu^+\nu_\mu\gamma$ decay

A Catalog of Background Stars Reddened by Dust in the Taurus Dark Clouds

Autor: Shenoy, S. S., Whittet, D. C. B., Ives, J. A., Watson, D. M.

Publikováno v: Astrophys.J.Suppl.176:457-466,2008

Normal field stars located behind dense clouds are a valuable resource in interstellar astrophysics, as they provide continua in which to study phenomena such as gas-phase and solid-state absorption features, interstellar extinction and polarization.
