An Asymmetric B Factory at 10^(36) Luminosity
The physics opportunities at an asymmetric B Factory operating at the unprecedented luminosity of 10^(36) cm^(–2) s^(–1) are unique and attractive. The accelerator appears to be practical and the challenges of performing a sensitive experiment in this environment can be met
First CP Violation Results from BABAR
We present a preliminary measurement of time-dependent CP-violating
asymmetries in B^0-->J/psi K_S and B^0-->psi(2S) K_S decays recorded by the
BABAR detector at the PEP-II asymmetric B Factory at SLAC. The data sample
consists of 9.0 fb-1 collected at the Upsilon(4S) resonance and 0.8 fb-1
off-resonance. One of the neutral B mesons, produced in pairs at the
Upsilon(4S), is fully reconstructed. The flavor of the other neutral B meson is
tagged at the time of its decay, mainly with the charge of identified leptons
and kaons. The time difference between the decays is determined by measuring
the distance between the decay vertices. Wrong-tag probabilities and the time
resolution function are measured with samples of fully-reconstructed
semileptonic and hadronic neutral B final states. The value of the asymmetry
amplitude, sin(2*beta), is determined from a maximum likelihood fit to the time
distribution of 120 tagged B^0-->J/psi K_S and B^0-->psi(2S) K_S candidates:
sin(2*beta) = 0.12+/-0.37(stat)+/-0.09(syst).Comment: 19 pages, 10 postscript figures, contributed to the Proceedings of

The tracker and calorimeter systems of the Mu2e experiment
The Mu2e experiment at Fermilab is a sensitive search for lepton flavor violation via muon-to-electron conversion in the field of an aluminum nucleus. The requirements for the tracking and calorimeter systems of the experiment, as well as the design of systems that fulfill these requirements, are briefly described
The Very Big ILC
In the spirit of Leon Lederman's 1977 proposal for the siting of the VBA, we
propose a version of the International Linear Collider along the US-Mexico
border
