Observation of two JPC=0++ isoscalar resonances at 1365 and 1520 MeV

Nonet Classi cation of Scalar/Isoscalar Resonances in the Mass Region below 1900 MeV: Observation of the Lightest Scalar Glueball

Here we summarize the results of the investigation of the IJ = 00 wave [1-3]: this investigation is devoted to the search for the lightest scalar glueball. In Refs. [1, 2], the q q-nonet classi cation of the scalar/isoscalar states is performed in the mass region below 1900 MeV basing on the following data: GAMS data for p! 0 n [4], n [5], n [6]; CERN-M unich data for p! + n [7]; Crystal Barre...

Isoscalar Resonances with J

Observation of Feshbach resonances between two different atomic species.

We have observed three Feshbach resonances in collisions between 6Li and 23Na atoms. The resonances were identified as narrow loss features when the magnetic field was varied. The molecular states causing these resonances have been identified, and additional 6Li-23Na resonances are predicted. These resonances will allow the study of degenerate Bose-Fermi mixtures with adjustable interactions an...

Observation of two charged bottomoniumlike resonances in Υ(5S) decays.

We report the observation of two narrow structures in the mass spectra of the π(±)Υ(nS) (n=1, 2, 3) and π(±)h(b)(mP) (m=1, 2) pairs that are produced in association with a single charged pion in Υ(5S) decays. The measured masses and widths of the two structures averaged over the five final states are M(1)=(10,607.2±2.0)  MeV/c2, Γ(1)=(18.4±2.4)  MeV, and M(2)=(10,652.2±1.5)  MeV/c2, Γ(2)=(11.5±...
