We observe a signal for the doubly charmed baryon Ξ c c+ in the charged decay mode Ξ c c+→
Λ c+ K− π+ in data from SELEX, the charm hadroproduction experiment at Fermilab. We …

We observe a signal for the doubly charmed baryon Ξ cc + in the decay mode Ξ cc + →pD +
K − to complement the previous reported decay Ξ cc + →Λ c + K − π + in data from SELEX, …

We report the first observation of a charm-strange meson D s J+(2632) at a mass of 2632.5±1.7
M e V/c 2 in data from SELEX, the charm hadro-production experiment E781 at Fermilab. …

The Σ − mean squared charge radius has been measured in the space-like Q 2 range 0.035–0.105
GeV 2 /c 2 by elastic scattering of a Σ − beam off atomic electrons. The measurement …

The collective synthesis of skeletally diverse Stemona alkaloids featuring tailored dyotropic
rearrangements of β‐lactones as key elements is described. Specifically, three typical 5/7/5 …

Spin precession of channeled particles in bent crystals has been observed for the first time.
Polarized Σ+ were channeled using bent Si crystals. These crystals provided an effective …

We present data from Fermilab experiment E781 (SELEX) on the hadroproduction asymmetry
for Λ ̄ c − compared to Λ c + as a function of x F , and on p t 2 distributions for Λ c + . …

Several mechanisms regarding the adverse health effects of nanomaterials have been
proposed. Among them, oxidative stress is considered to be one of the most important. Many in …

We have mesured the polarization of 375-GeV/c Σ+ and Σ− hyperons produced by 800-GeV/c
protons incident on a Cu target. We find that the Σ+ polarization rises with increasing pt to …

Aims: Urinary 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG) is a widely used biomarker
of oxidative stress. However, variability between chromatographic and ELISA methods …
