Based on the measurements of (D+ s ,D +) → f0(1370)π we determine, in a model independent way, the allowed ss̄ content in the scalar meson f0(1370). We find that, on the one hand, if this isoscalar resonance is a pure nn̄ state [nn̄ ≡ (uū + dd̄)/ √ 2 ], a very large W -annihilation term will be needed to accommodate D+ s → f0(1370)π. On the other hand, the ss̄ component of f0(1370) should be small e...

We evaluated the ingestion of anti-sheep erythrocyte (anti-E) IgG- and IgM-coated sheep erythrocytes by murine peritoneal macrophages exposed to cefodizime, a new semisynthetic cephalosporin, and other antibiotics. Cefodizime enhanced the ingestion of anti-E IgG-coated erythrocytes by peritoneal macrophages from CD-1 and BALB/c mice in a dose-dependent manner, but had no effect on uncoated or I...

The ρρ interaction in the hidden gauge formalism and the f 0 (1370) and f 2 (1270) resonances. Abstract We have studied the interaction of vectors mesons within the hidden gauge formalism and applied it to the particular case of the ρρ interaction. We find a strong attraction in the isospin, spin channels I,S=0,0 and 0,2, which is enough to bind the ρρ system. We also find that the attraction i...

Riluzole, a benzothiazole derivative, has been shown to be effective in prolonging survival in amyotrophic lateral sclerosis. The mechanisms by which riluzole exerts neuroprotective effects in amyotrophic lateral sclerosis remains to be fully elucidated, although inhibition of glutamatergic transmission and modulation of Na + channel function have been proposed. In an attempt to determine the m...

Claims have been made that f0(1370) does not exist. The five primary sets of data requiring its existence are refitted with suitable Breit–Wigner amplitudes. Major dispersive effects due to the opening of the 4π threshold are included for the first time; the σ→ 4π amplitude plays a strong role. Crystal Barrel data on p̄p→ 3π at rest require f0(1370) signals of at least 32 and 33 standard deviati...

Based on a 3×3 mass matrix describing the mixing of the scalar states f0(1370), f0(1500) and f0(1710), the hadronic decays of the three states are investigated. Taking into account the two possible assumptions concerning the mass level order of the bare states |N〉 = |uū + dd̄〉/ √ 2, |S〉 = |ss̄〉 and |G〉 = |gg〉 in the scalar sector, MG > MS > MN and MG > MN > MS , the glueball-quarkonia content of ...

The phytoplankton in warm oligotrophic regions of the open oceans is dominated by ,2-mm cells too small for efficient direct consumption by mesozooplankton. However, these primary producers are hypothetically linked to higher trophic levels via the cascading impacts of mesozooplankton grazing on intermediate consumers. To assess the magnitudes of these indirect trophic linkages, grazing experim...

The assignments of the isoscalar scalar mesons f0(980), f0(1370), and f0(1500) in terms of their q̄q substructure is still a matter of heated dispute. Here we employ the weak and electromagnetic decays D+ s → f0π and f0 → γγ, respectively, to identify the f0(980) and f0(1500) as mostly s̄s, and the f0(1370) as dominantly n̄n, in agreement with previous work. The two-photon decays can be satisfacto...
