Humans are not capable of synthesizing carotenoids de novo and thus, their presence in human tissues is entirely of dietary origin. Consumption of essential carotenoids is reduced due to the lower intake of fruits and vegetables. Microalgae are a good source of carotenoids that can be exploited. In the present work, carotenoids rich extracts from(More)
We present the result of a search for charged Higgs decays of the top quark, produced in pp̄ collisions at √ s = 1.8 TeV. When the charged Higgs is heavy and decays to a tau lepton, which subsequently decays hadronically, the resulting events have a unique signature: large missing transverse energy and the low-charged-multiplicity tau. Data collected in the(More)

We report the observations of the decays B+ → ψ(2S)K+ and B0 → ψ(2S)K∗(892)0 in pp̄ collisions at a center-of-mass energy of 1.8 TeV using a 110 pb−1 data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays B+ → J/ψK+ and B0 → J/ψK∗(892)0 and measure the six ratios of branching fractions of these four decays. The relative(More)
The Supernova / Acceleration Probe (SNAP) is a proposed space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe’s expansion by performing a series of complementary systematics-controlled astrophysical measurements.

We present a detailed description of a search for anomalous production of missing ET (6ET), jets, leptons (e, μ, τ), b-quarks, or additional photons in events containing two isolated, central (|η| < 1.0) photons with ET > 12 GeV. The results are consistent with standard model expectations, with the possible exception of one event that has in addition to the(More)
