CP violation in B{sup 0}{bar B}{sup 0} mixing is characterized by the value of the parameter |q/p| being different from 1, and the Standard Model predicts this difference to be smaller than 10{sup -3}. We present a measurement of this parameter using a partial reconstruction of one of the B mesons in the semileptonic channel D*{sup -}{ell}{sup +}{nu}{sub {ell}}, where only the hard lepton and the soft pion from the D*{sup -} {yields} {bar D}{sup 0}{pi}{sup -} decay are reconstructed. The flavor of the other B is determined by means of lepton tagging. The determination of |q/p| is then performed with a fit to the proper time difference of the two B decays. We use a luminosity of 200.8 fb{sup -1}, collected at the {Upsilon}(4S) resonance by the BABAR detector at the PEP-II asymmetrical-energy e{sup +}e{sup -} collider, in the period 1999-2004. We obtain the preliminary result: |q/p| - 1 = (6.5 {+-} 3.4(stat.) {+-} 2.0(syst.)) {center_dot} 10{sup -3}.

We perform the first three-dimensional measurement of the amplitudes of B {yields} {psi}(2S)K* and B {yields} {chi}{sub c1}K* decays and update our previous measurement for B {yields} J/{psi} K*. We use a data sample collected with the BABAR detector at the PEP-II storage ring, representing 232 million produced B{bar B} pairs. The longitudinal polarization of decays to the 1{sup ++} {chi}{sub c1} meson together with a K* meson, is found to be larger than that for the decay to the 1{sup --} {Psi} mesons. No direct CP-violating charge asymmetry is observed.

The authors present an updated measurement of the time-dependent CP-violating asymmetry in B{sup 0} {yields} K{sub S}{sup 0}K{sub S}{sup 0}K{sub S}{sup 0} decays based on 347 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. The authors obtain the CP asymmetries S{sub f} = -0.66 {+-} 0.26 {+-} 0.08 and C{sub f} = -0.14 {+-} 0.22 {+-} 0.05, where the first uncertainties are statistical and the second systematic.

The authors report first observations of the decays B{sup -} {yields} D{sub s}{sup (*)+} K{sup -}{pi}{sup -}, using 292 fb{sup -1} of data collected at the {Upsilon}(4S) resonance energy by the BABAR detector at the PEP-II e{sup +}e{sup -} collider. The branching fractions are measured to be {Beta}(B{sup -} {yields} D{sub s}{sup +}K{sup -}{pi}{sup -}) = (1.88 {+-} 0.13 {+-} 0.41) {center_dot} 10{sup -4} and {Beta}(B{sup -} {yields} D{sub s}{sup *+}K{sup -}{pi}{sup -}) = (1.84 {+-} 0.19 {+-} 0.40) {center_dot} 10{sup -4}.

We present a study of two states decaying to {Lambda}{sub c}{sup +} K{sup -} {pi}{sup +} using the BABAR detector at the SLAC PEP-II asymmetric-energy e{sup +}e{sup -} storage rings. We use an integrated luminosity of 288.5 fb{sup -1} collected at the center-of-mass energy {radical}s = 10.58 GeV, near the peak of the {Upsilon}(4S) resonance, plus 27.2 fb{sup -1} collected approximately 40MeV below this energy. We search for the particles {Xi}{sub c}(2980){sup +} and {Xi}{sub c}(3077){sup +}, recently discovered by the Belle Collaboration, in their decays to {Lambda}{sub c}{sup +}K{sup -}{pi}{sup +}, where {Lambda}{sub c}{sup +} {yields} pK{sup -}{pi}{sup +}. We find a signal with 7.0{sigma} significance for the {Xi}{sub c}(2980){sup +} state with a mass difference with respect to the {Lambda}{sub c}{sup +} of (680.6 {+-} 1.9 {+-} 1.0)MeV/c{sup 2} (first error is statistical and second error is systematic). The measured width for this state is (23.6 {+-} 2.8 {+-} 1.3)MeV, and the yield is 284 {+-} 45 {+-} 46 events. We find a signal with 8.6{sigma} significance for the {Xi}{sub c}(3077){sup +} state with a mass difference with respect to the {Lambda}{sub c}{sup +} of (790.0 {+-} 0.7 {+-} 0.2) MeV/c{sup 2}, a width of (6.2 {+-} 1.6 …

In 2004, the first two sextants of the new Limited Streamer Tube (LST) detector were installed in the BABAR experiment to replace the ageing Resistive Plate Chambers (RPCs) as active detectors for the BABAR Instrumented Flux Return (IFR) muon system. Each streamer tube of the new detector consists of 8 cells. The cell walls are coated with graphite paint and a 100 {micro}m wire forms the anode. These wires are coupled in pairs inside the tubes resulting in 4 independent two-cell segments per LST. High voltage (HV) is applied to the 4 segments through a custom connector that also provides the decoupling capacitor to pick up the detector signals from the anode wires. The BABAR LST detector is operated at 5.5 kV. The high voltage system for the LST detector was designed and built at The Ohio State University (OSU HVPS). Each of the 25 supplies built for BaBar provides 80 output channels with individual current monitoring and overcurrent protection. For each group of 20 channels the HV can be adjusted between 0 and 6 kV. A 4-fold fan-out is integrated in the power supplies to provide a total of 320 outputs. The power supplies are controlled through built-in CANbus …

We consider a scalar field, such as the Higgs boson H, coupled to gluons via the effective operator H tr G{sub {mu}{nu}} G{sup {mu}{nu}} induced by a heavy-quark loop. We treat H as the real part of a complex field {phi} which couples to the self-dual part of the gluon field-strength, via the operator {phi} tr G{sub SD {mu}{nu}} G{sub SD}{sup {mu}{nu}}, whereas the conjugate field {phi} couples to the anti-self-dual part. There are three infinite sequences of amplitudes coupling {phi} to quarks and gluons that vanish at tree level, and hence are finite at one loop, in the QCD coupling. Using on-shell recursion relations, we find compact expressions for these three sequences of amplitudes and discuss their analytic properties.

A new type of compact induction accelerator is under development at the Lawrence Livermore National Laboratory that promises to increase the average accelerating gradient by at least an order of magnitude over that of existing induction machines. The machine is based on the use of high gradient vacuum insulators, advanced dielectric materials and switches and is being developed as a compact flash x-ray radiography source. Research describing an extreme variant of this technology aimed at proton therapy for cancer will be presented.

In this paper we revisit the topological twisted sigma model with H-flux. We explicitly expand and then twist the worldsheet Lagrangian for bi-Hermitian geometry. we show that the resulting action consists of a BRST exact term and pullback terms, which only depend on one of the two generalized complex structures and the B-field. We then discuss the topological feature of the model.

We report preliminary measurements of the exclusive charmless semileptonic branching fractions of the B{sup +} {yields} {eta}{ell}{sup +}{nu} and B{sup +} {yields} {eta}'{ell}{sup +}{nu} decays. These measurements are based on 316 fb{sup -1} of data collected at the {Upsilon}(4S) resonance by the BABAR detector. In events in which the decay of one B meson to a hadronic final state is fully reconstructed, the semileptonic decay of the recoiling B meson is identified by the detection of a charged lepton and an {eta} or {eta}'. We measure the branching fraction {Beta}(B{sup +} {yields} {eta}{ell}{sup +}{nu}) = (0.84 {+-} 0.27 {+-} 0.21) x 10{sup -4}, where the first error is statistical and the second one systematic. We also set an upper limit on the branching fraction of {Beta}(B{sup +} {yields} {eta}{ell}{sup +}{nu}) < 1.4 x 10{sup -4} and {Beta}(B{sup +} {yields} {eta}'{ell}{sup +}{nu}) < 1.3 x 10{sup -4} at the 90% confidence level.

The National Museum of the Pacific War presents an oral interview with Tony Defusco. Defusco joined the Marine Corps in June 1942 and received basic training at Parris Island. He received further training as a rifleman in California. Upon completion, he was assigned to the 25th Marines where he joined BN2, Battalion Intelligence. In January 1944 he invaded the Marshall Islands, focusing on Namur. Afterward his unit went from island to island in search of information on Amelia Earhart. He describes his base in Maui as desolate. His next invasion was in Saipan, in June, where he went ashore at the old sugar refinery. He recalls a dogfight between Zeros and Wildcats, appreciating the protection from the Navy pilots. His unit lost men when Japanese infiltrated their camp in the middle of the night. And one morning, he tried to save a good friend who was fatally wounded by shelling and gunfire. He next went to Tinian and on to Iwo Jima, where he was wounded. He was immediately taken by Higgins boat to a carrier with medical personnel aboard and was later treated at hospitals in Saipan, San Francisco, and North Carolina. Defusco returned home and was discharged in …

Understanding the quantum efficiency (QE) of a metal photocathode in an s-band RF gun is important to limit the drive laser energy requirement and provide the best quality electron beam. Systematic measurements of the qe vs. wavelength for varying surface contamination have been performed on copper samples using x-ray photoelectron spectroscopy (XPS). The sample is first cleaned to the theoretical limit of QE using a 1 keV hydrogen ion beam. The H-ion beam cleans an area approximately 1cm in diameter and has no effect on the surface roughness while removing essentially all contaminants and lowering the work function to 4.3eV[1]. The sample is then exposed to atmospheric contaminants (nitrogen and oxygen) and measured again with XPS to determine the degree of contamination and their effect on the QE. These results and comparison with theory are presented.
