Observation of a peaking structure in the J/ψφmass spectrum from B±→J/ψφK±decays
Article history: Received 26 September 2013 Received in revised form 11 April 2014 Accepted 7 May 2014 Available online 22 May 2014 Editor: M. Doser A peaking structure in the J/ψφ mass spectrum near threshold is observed in B± → J/ψφK± decays, produced in pp collisions at √ s = 7 TeV collected with the CMS detector at the LHC. The data sample, selected on the basis of the dimuon decay mode of ...

Observation of a membrane fusion intermediate structure.
We report the observation of a phase of phospholipid that contains a structure similar to the commonly postulated interbilayer state that is crucial to membrane fusion. The widely accepted model for membrane fusion suggests that there is an intermediate state in which the two contacting monolayers become continuous via an hourglass-shaped structure called a stalk. Many efforts have been made to...
متن کاملObservation of CHG Spectrum at UVSOR-II
At synchrotron light sources, the drift of the orbit of the electrons in the storage ring causes a drift of the light source position, which affects user’s experiments. At UVSOR-II, an RF feedback system [1] has been operating to suppress the orbit drift on the horizontal plane caused by the thermal expansion of the storage ring floor. However, on the vertical plane, there’s no system to stabil...
متن کاملObservation of molecular hyperfine structure in the extreme ultraviolet: The HF C-X spectrum.
Clearly resolved hyperfine structure has been observed in the extreme ultraviolet (XUV) spectra of the C (1)Pi, v=0-X (1)Sigma(+), v=0 transition of H(19)F obtained through 1 XUV+1 UV resonance enhanced multiphoton ionization spectroscopy. The hyperfine splitting within the R-branch lines shows significant perturbations, which we attribute to mixing with the rotational levels of the nearby v=29...
