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.

Precision measurements of the timelike electromagnetic form factors of pion, kaon, and proton.

Abstract:

Using 20.7 pb(-1) of e(+)e(-) annihilation data taken at sq.rt(r) = 3.671 GeV with the CLEO-c detector, precision measurements of the electromagnetic form factors of the charged pion, charged kaon, and proton have been made for timelike momentum transfer of |Q(2)| = 13.48 GeV(2) by the reaction e(+)e(-) --> h(+)h(-). The measurements are the first ever with identified pions and kaons of |Q(2)| > 4 GeV(2), with the results F(13.48 GeV(2)) = 0.075 +/- 0.008(stat) +/- 0.005(syst) and F(K)(13.48 GeV(2)) = 0.063 +/- 0.004(stat) +/- 0.001(syst). The result for the proton, assuming G(p)(E) = G(p)(M), is G(p)(M)(13.48 GeV(2)) = 0.014 +/- 0.002(stat) +/- 0.001(syst), which is in agreement with earlier results.

Abstract:

We report on a search for Bs0â†Î+Î- and Bd0â†Î+Î- decays in ppÂcollisions at s=1.96TeV using 364â€â€pb-1 of data collected by the CDF II detector at the Fermilab Tevatron Collider. After applying all selection requirements, we observe no candidates inside the Bs0 or Bd0 mass windows. The resulting upper limits on the branching fractions are B(Bs0↠Î+Î-)<1.5Ã-10-7 and B(Bd0â†Î+Î-) <3.9Ã-10-8 at 90% confidence level. © 2005 The American Physical Society.
