On the Delta I = 1/2 Rule in Holographic QCD

ArXiv hep-ph/0512089 (2005)

Abstract:

We study the $\Delta I = 1/2$ rule for kaon decays and the $B_K$ parameter for $K^0 - {\bar K}^0$ mixing in a dual 5-dimensional holographic QCD model. We perform, in the chiral limit, computations of the relevant four-point current-current correlators, which depend upon self-interactions among the 5D bulk fields. Spontaneous chiral symmetry breaking ($\chi$SB) is realized through boundary conditions on the bulk fields. Numerical results are analyzed in comparison with QCD, chiral perturbation theory ($\chi$PT) and data, finding reasonable agreement with the experimental values of the $g_8$ and $g_{27}$ parameters describing the $\Delta I =1/2,3/2$ decay channels.

The cornell/purdue TPC

LCWS 2005 - 2005 International Linear Collider Workshop (2005)

Authors:

DP Peterson, L Fields, RS Galik, P Onyisi, G Bolla, IPJ Shipsey

Abstract:

A prototype TPC has been completed and commissioned at Cornell for the purpose of evaluating performance and reliability of candidate gas-amplification devices and pad configurations. The TPC has an active area of 10cm square and a drift length of 64cm. The current readout electronics includes 32 channels of 14 bit, 105 MHz 14flash-ADCs. Baseline measurements have been taken with a wire gas-amplification module. The Purdue group has prepared a single GEM readout module. First results using the wire gas-amplification and single GEM are described.
