Observation of D^{0} Meson Decays to π^{+}π^{-}μ^{+}μ^{-} and K^{+}K^{-}μ^{+}μ^{-} Final States.

The first observation of the D^{0}→π^{+}π^{-}μ^{+}μ^{-} and D^{0}→K^{+}K^{-}μ^{+}μ^{-} decays is reported using a sample of proton-proton collisions collected by LHCb at a center-of-mass energy of 8 TeV, and corresponding to 2  fb^{-1} of integrated luminosity. The corresponding branching fractions are measured using as normalization the decay D^{0}→K^{-}π^{+}[μ^{+}μ^{-}]_{ρ^{0}/ω}, where the t...

Search for D+(s)→π+μ+μ− and D+(s)→π−μ+μ+ decays

Article history: Received 24 April 2013 Received in revised form 3 June 2013 Accepted 4 June 2013 Available online 7 June 2013 Editor: L. Rolandi A search for non-resonant D(s) → π+μ+μ− and D(s) → π−μ+μ+ decays is performed using proton– proton collision data, corresponding to an integrated luminosity of 1.0 fb−1, at √ s = 7 TeV recorded by the LHCb experiment in 2011. No signals are observed a...

The Crab Nebula at 850 Μ Μ Μ Μ Μm

Observations of the Crab Nebula at 850 µm made with the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope are presented. A variety of chop-throws and scanning directions was used in these observations, to well sample structure over a range of scales and directions. The resulting image, which was restored using a MEM algorithm, has a resolution of 17 arcsec, ...

The α − η − μ and α − κ − μ Fading Distributions

In this paper two new fading distributions, the α−η−μ Distribution and α−κ−μ Distribution, are presented. The α − η − μ distribution includes the α − μ, Nakagami-m, Nakagami-q, Weibull, Hoyt, Rayleigh, Exponential, and the OneSided Gaussian distributions as special cases. The α − κ − μ distribution includes the α − μ, Nakagami-m, Weibull, Rice, Rayleigh, Exponential, and the One-Sided Gaussian ...
