Observations of the D and E mesons and possible three-kaon enhancements in pi-p→K0K±pi±X,K0K+K-X at 50 and 100 GeV/c

We present results from the study of multikaon final states in the reactions π-p→K0K±π∓X̃, K0K+K-X̃ at 50 and 100 GeV/c. Here X̃ is semi-inclusive, that is, a specific forward topology and an interaction registering in the counters surrounding the target are required. The D(1285) meson is seen in the δπ mode, while the E(1420) meson is observed in both the δπ and the K*K modes. In addition, there are two possible enhancements in the three-kaon final state. The first (M∼1840 MeV) is associated with the K0φ mode and is consistent with being the charmed D0. The second, a K* state (M=2003±14 MeV, Γ=87±43 MeV), decays into KA2

Study of A_2 production in the reaction π^-p→K^0K^-p at 50, 100, and 175 GeV/c

The reaction π^-p→K^0K^-p has been measured from 50 to 175 GeV/c. The production characteristics of the A_2 have been analyzed. We find spin and t dependence similar to lower energies, but the cross section falls rapidly with energy. In a Regge description of π^-p→A_2^-p our data imply a rather small Pomeron-exchange component

F-18-Fluorodeoxyglucose Positron Emission Tomography/CT Effectively Identifying Source of Infection in a Patient With Multiple Dialysis Arteriovenous Fistula Access Points.

Radiologic imaging techniques, such as F-18-fluorodeoxyglucose positron emission tomography/computerized tomography (FDG PET/CT), provide diagnostic value in a variety of diseases. In cases of suspected infection, FDG PET/CT can find areas of fluorodeoxyglucose metabolism, correlating with local acute inflammation. The following case involves a man with end-stage renal disease (ESRD), who presented with symptoms of infection and positive blood cultures with high suspicion of arteriovenous fistula as the source of infection. The patient also had two central lines that could be a site of infection. Concerns for patient's persistent positive blood cultures necessitated FDG PET/CT to confirm site of infection. Confirming active infection and the source of infection guides therapeutic measures and eliminates concern for other disease etiologies common in patients with ESRD
