Two-photon production of pion pairs.
We present a new high-statistics measurement of the cross section for the process {ital e}{sup +}{ital e}{sup {minus}}{r arrow}{ital e}{sup +}{ital e}{sup {minus}}{pi}{sup +}{pi}{sup {minus}} at a center-of-mass energy of 29 GeV for invariant pion-pair masses {ital M}({pi}{sup +}{pi}{sup {minus}}) between 350 MeV/{ital c}{sup 2} and 1.6 GeV/{ital c}{sup 2}. We observe the {ital f}{sub 2}(1270) and measure its radiative width to be 3.15{plus minus}0.04{plus minus}0.39 keV. We also observe an enhancement in the {pi}{sup +}{pi}{sup {minus}} spectrum near 1 GeV. General agreement is found with unitarized models of the {gamma}{gamma}{r arrow}{pi}{sup +}{pi}{sup {minus}} reaction that include final-state interactions.

title: Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
abstract: Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using a sample of proton-proton collision data collected at sqrt(s)=7 TeV with the CMS detector at the LHC in 2011, with the missing transverse energy distribution as the principal search variable. The integrated luminosity of the sample is 4.98 inverse femtobarns. The observed number of events is found to be consistent with the standard model expectation, which is evaluated using control samples in the data. The results are used to constrain cross sections for the production of supersymmetric particles decaying to b-quark-enriched final states in the context of simplified model spectra.

title: Performance of the scintillating fibre detector in the upgraded UA2 detector
abstract: A large scintillating fibre detector consisting of ≈ 60 000 scintillating plastic fibres of 1 mm diameter and 2.4 m length has been used successfully as a tracking and preshower detector in the UA2 experiment at CERN. The detector readout, the pattern recognition algorithm and the results from the pp data taking run are described.

title: Measurement of the W boson mass.
abstract: We present a measurement of the W boson mass in W-->e(nu) decays using 1 fb-1 of data collected with the D0 detector during Run II of the Fermilab Tevatron collider. With a sample of 499830 W-->e(nu) candidate events, we measure M(W)=80.401+/-0.043 GeV. This is the most precise measurement from a single experiment.

title: Smoothed Particle Hydrodynamics Simulations of Apsidal and Nodal Superhumps.
abstract: In recent years, a handful of systems have been observed to show "negative" (nodal) superhumps, with periods slightly shorter than the orbital period. It has been suggested that these modes are a consequence of the slow retrograde precession of the line of nodes in a disk tilted with respect to the orbital plane. Our simulations confirm and refine this model: they suggest a roughly axisymmetric, retrogradely precessing, tilted disk that is driven at a period slightly less than half the orbital period as the tidal field of the orbiting secondary encounters, in turn, the two halves of the disk above and below the midplane. Each of these passings leads to viscous dissipation on one face of an optically thick disk-observers on opposite sides of the disk would each observe one brightening per orbit, but 180 degrees out of phase with each other.
