title: Development of characterization techniques for X-band accelerator structures
abstract: The recent effort to develop accelerator structures for the Next Linear Collider (NLC), requires an accompanying development of accurate and efficient techniques to characterize these structures at different phases of development. At SLAC, we have been developing different microwave techniques to verify predictions from computer simulations in the design phase, to insure that the machined cells are within the design tolerances, and finally, to confirm overall RF performance of the completed structure. For this final test, a semi-automated system was built to implement the bead-pulling technique under traveling-wave conditions. This technique maps the phase and amplitude of the axial electric field along the structure.

title: Existence of a proton halo in Al-23 and its significance
abstract: Reaction cross section sigma(R) of proton-rich isotones (N = 10) near Al-23 and Al isotopes (Al23-28) on C target have been measured at intermediate energies around 30 MeV/nucleon. An abnormal increase of the experimental sigma(R) is observed for Al-23 and it suggests that there is an anomalously large matter rms radius in Al-23. Together with the very weakly binding of the last proton (S-p = 0.125 MeV), it indicates that there is a proton halo in Al-23. This conclusion is also supported by the difference factor d which is deduced from the measured and theoretical sigma(R) in the Glauber or Boltzmann-Uehling-Uhlenbeck model and is used for the manifest of halo phenomena. The theoretical calculation based,on the relativistic density dependent Hartree model shows that there is a proton halo when the last proton is in the 2s(1/2) orbit in Al-23. The significance of the proton halo in Al-23 is discussed.

title: Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at s$$ \sqrt{s} $$ = 7 TeV
abstract: A bstractThe production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were recorded in 2011 with the CMS detector and correspond to an integrated luminosity of 5 fb−1. The Z(ℓℓ) + b-jets cross sections (where ℓℓ = μμ or ee) are measured separately for a Z boson produced with exactly one b jet and with at least two b jets. In addition, a cross section ratio is extracted for a Z boson produced with at least one b jet, relative to a Z boson produced with at least one jet. The measured cross sections are compared to various theoretical predictions, and the data favour the predictions in the five-flavour scheme, where b quarks are assumed massless. The kinematic properties of the reconstructed particles are compared with the predictions from the MadGraph event generator using the pythia parton shower simulation.
