The authors regret that there were errors in equations (1), (3), and (4), and in Table 1. The errors occurred while transcribing parameters and numerical values from the computer code to the journal text. However, correct values were used in the computations, so no corrections are required to the main conclusions or the attached computer programs. The authors thank Ching-Yuan Huang and Jun Fang for pointing out the errors in the text.Equation (1) should read:

XV goals. We then discuss the baseline experimental facilities. Our baseline design is an accelerator of 500 GeV center-of-mass energy, with polarized e-beams, and with two interaction regions that share the luminosity. The design envisions a number of upgrade paths. These include low-energy precision measurements in one of the two regions and e+e-collisions at multi-TeV energies in the other. The logic of these plans is described in some detail. In the subsequent chapters, we discuss the possible options of positron polarization, operation of a yy collider by laser backscattering from electron beams, and operation for e-e-collisions. In each case, we review the promise and the technological problems of the approach.

We present selected new results on strong interaction physics from the SLD experiment at the SLAC Linear Collider (SLC), symmetry tests of bbg vertex, the rate of secondary bb production via gluon splitting, the B hadron energy spectrum and rapidity correlations between identified charged hadrons. The parity violation in Z 0 → bbg decays is consistent with electroweak theory plus QCD. New tests of T-and CP-conservation at the bbg vertex are performed. A new measurement of the rate of gluon splitting into bb pairs yields g bb = 0.00307 ± 0.00071(stat.) ± 0.00066(syst.) (Preliminary). The B hadron energy spectrum is measured using a new inclusive technique, allowing tests of predictions for its shape and a measurement of x B = 0.714 ± 0.005(stat.) ± 0.007(syst.) (Preliminary). A study of correlations in rapidity between pairs of identified π ± , K ± and p/p confirms that strangeness and baryon number are conserved locally, and shows local charge conservation between meson-baryon and strange-nonstrange pairs. Flavor-dependent long-range correlations are observed for all combinations of these hadron species. The first study of correlations using signed rapidities is done and find the first direct observation of baryon number ordering along the qq axis.

We present the yield and spectra of stable secondary particles ( ; e AE ; e ;¯e, , and¯) of p-p interaction in parameterized formulae to facilitate calculations involving them in astronomical environments. The formulae are derived from the up-to-date p-p interaction model by Kamae et al. (2005), which incorporates the logarithmically rising inelastic cross section, the diffraction dissociation process, and the Feynman scaling violation. To improve fidelity to experimental data in lower energies, two baryon resonance contributions have been added: one representing Á(1232) and the other representing multiple resonances around 1600 MeV/c À2 . The parameterized formulae predict that all secondary particle spectra be harder by about 0.05 in power-law indices than that of the incident proton and their inclusive cross sections be larger than those predicted by p-p interaction models based on the Feynman scaling.

The proposed International Linear Collider (ILC) is well-suited for discovering physics beyond the Standard Model and for precisely unraveling the structure of the underlying physics. The physics return can be maximized by the use of polarized beams. This report shows the paramount role of polarized beams and summarizes the benefits obtained from polarizing the positron beam, as well as the electron beam. The physics case for this option is illustrated explicitly by analyzing reference reactions in different physics scenarios. The results show that positron polarization, combined with the clean experimental environment provided by the linear collider, allows to improve strongly the potential of searches for new particles and the identification of their dynamics, which opens the road to resolve shortcomings of the Standard Model. The report also presents an overview of possible designs for polarizing both beams at the ILC, as well as for measuring their polarization.2

We have observed a narrow state near 2.32 GeV/c(2) in the inclusive D(+)(s)pi(0) invariant mass distribution from e(+)e(-) annihilation data at energies near 10.6 GeV. The observed width is consistent with the experimental resolution. The small intrinsic width and the quantum numbers of the final state indicate that the decay violates isospin conservation. The state has natural spin-parity and the low mass suggests a J(P)=0(+) assignment. The data sample corresponds to an integrated luminosity of 91 fb(-1) recorded by the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)e(-) storage ring.
