The LCO/Palomar 10,000 km/sec Cluster Survey. II. Constraints on Large-Scale Streaming

Jeffrey A. Willick

The LCO/Palomar 10,000 km/sec (LP10K) Tully-Fisher (TF) data set is used to test for bulk streaming motions on a ~150 Mpc scale. The sample consists of 172 cluster galaxies in the…

Model-Independent Analysis of B -> pi K Decays and Bounds on the Weak Phase gamma

Matthias Neubert

A general parametrization of the amplitudes for the rare two-body decays B -> pi K is introduced, which makes maximal use of theoretical constraints arising from flavour symmetries…

Inflation and Large Internal Dimensions

Nemanja Kaloper, Andrei Linde

We consider some aspects of inflation in models with large internal dimensions. If inflation occurs on a 3D wall after the stabilization of internal dimensions in the models with l…

Instant Preheating

Gary Felder, Lev Kofman, Andrei Linde

We describe a new efficient mechanism of reheating. Immediately after rolling down the rapidly moving inflaton field produces particles , which may be either bosons or fermi…

Superisometries of the adS*S Superspace

Piet Claus, Renata Kallosh

We find the superisometry of the near-horizon superspace, forming the superconformal algebra. We present here the explicit form of the transformation of the bosonic and fermionic c…

Measurement of the form-factor ratios for D_s^+ -> phi ell^+ nu_ell

Fermilab E791 Collaboration, E. M. Aitala, S. Amato

We have measured the form factor ratios r_V = V(0)/A_1(0) and r_2 = A_2(0)/A_1(0) for the decay D_s^+ -> phi ell^+ nu_ell, phi -> K^+ K^-, using data from charm hadroproduction exp…
