Evidence for the h_b(1P) meson in the decay Upsilon(3S) --> pi0 h_b(1P)
The BABAR Collaboration, J. P. Lees, V. Poireau +406
Using a sample of 122 million Upsilon(3S) events recorded with the BaBar detector at the PEP-II asymmetric-energy e+e- collider at SLAC, we search for the spin-singlet pa…
Initial-State Radiation Measurement of the e+e- -> pi+pi-pi+pi- Cross Section
J. P. Lees, V. Poireau, V. Tisserand +383
We study the process e+e- -> pi+pi-pi+pi-gamma, with a photon emitted from the initial-state electron or positron, using 454.3 fb^-1 of data collected with the BABAR detector at SL…
A Test Facility for the International Linear Collider at SLAC End Station A, for Prototypes of Beam Delivery and IR Components
M. Woods, R. Erickson, J. Frisch +58
The SLAC Linac can deliver damped bunches with ILC parameters for bunch charge and bunch length to End Station A. A 10Hz beam at 28.5 GeV energy can be delivered there, parasitic w…
A Measurement of the Semileptonic Branching Fraction of the B_s Meson
The BaBar Collaboration, J. P. Lees, V. Poireau +383
We report a measurement of the inclusive semileptonic branching fraction of the B_s meson using data collected with the BaBar detector in the center-of-mass (CM) energy region abov…
Search for hadronic decays of a light Higgs boson in the radiative decay Upsilon --> gamma A0
The BABAR Collaboration, J. P. Lees, V. Poireau +385
We search for hadronic decays of a light Higgs boson (A0) produced in radiative decays of an Upsilon(2S) or Upsilon(3S) meson, Upsilon --> gamma A0. The data have been recorded by…
Design and Electronics Commissioning of the Physics Prototype of a Si-W Electromagnetic Calorimeter for the International Linear Collider
CALICE Collaboration, J. Repond, J. Yu +114
The CALICE collaboration is studying the design of high performance electromagnetic and hadronic calorimeters for future International Linear Collider detectors. For the electromag…
Study of radiative bottomonium transitions using converted photons
The BABAR Collaboration, J. P. Lees, V. Poireau +388
We use 111+/-1 million Upsilon(3S) and 89+/-1 million Upsilon(2S) events recorded by the BaBar detector at the PEP-II B-factory at SLAC to perform a study of radiative transitions…
Fractional vortices on grain boundaries --- the case for broken time reversal symmetry in high temperature superconductors
D. Bailey, M. Sigrist, R. B. Laughlin
We discuss the problem of broken time reversal symmetry near grain boundaries in a d-wave superconductor based on a Ginzburg-Landau theory. It is shown that such a state can lead t…
Observation of the baryonic B decay B0bar --> Lambda_c^+ anti-Lambda K-
The BABAR Collaboration, J. P. Lees, V. Poireau +384
We report the observation of the baryonic B decay B0bar --> Lambda_c^+ anti-Lambda K- with a significance larger than 7 standard deviations based on 471x10^6$ BBbar pairs collected…
Experiments conducted in the burning plasma regime with inertial fusion implosions
J. S. Ross, J. E. Ralph, A. B. Zylstra +149
An experimental program is currently underway at the National Ignition Facility (NIF) to compress deuterium and tritium (DT) fuel to densities and temperatures sufficient to achiev…
