Evolution of the TRT backend and the new TRT-TTC board (2009)

S. Baron, L. Cardiel-sas, P. Farthouat, P. Lichard, T. Rogmo, O. Rohne, ...

The Transition Radiation Tracker, made of 370000 cylindrical straws, is a combined tracking and electron identification detector, which is part of the ATLAS Inner Detector at the CERN LHC. The TRT...

Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics (2008)

Abat, E., Abbott, B., Abdallah, J., Abdelalim, A. A., Abdesselam, A., ...

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance...

First observation of the decay K+ -> e+ nu mu+ mu- (2005)

Ma, H., Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D. R., Cheung, N., ...

Experiment 865 at the Brookhaven AGS has observed the decay K^+ -> e^+ nu mu^+ mu^-. The branching ratio extracted is (1.72 +/- 0.37(stat) +/- 0.17(syst) +/- 0.19(model)) x 10^{-8} where the third...

An Improved upper limit on the decay K^+ -> pi^+ mu^+ e^- (2005)

Sher, Aleksey, Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D. R., Cheung, N., ...

Based on results of a search for the lepton-family-number-violating decay $K^+ \to \pi^+\mu^+ e^-$ with data collected by experiment E865 at the Alternating Gradient Synchrotron of Brookhaven...

New, high statistics measurement of the K+ -> pi0 e+ nu (Ke3) branching ratio (2003)

Sher, A., Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D. R., Cheung, N., ...

E865 at the Brookhaven National Laboratory AGS collected about 70,000 K+(e3) events with the purpose of measuring the relative K+(e3) branching ratio. The pi0 in all the decays was detected using the...

High statistics measurement of Ke4 decay properties (2003)

Pislak, S., Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D. R., Cheung, N., ...

We report experimental details and results of a new measurement of the decay K+ -> pi+pi-e+nue (Ke4}. A sample of more than 400,000 Ke4 events with low background has been collected by Experiment 865...

Experimental Study of the Radiative Decays K+ -> mu+ nu e+e- and K+ -> e+ nu e+e- (2002)

Poblaguev, A. A., Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D. R., Cheung, N., ...

Experiment 865 at the Brookhaven AGS obtained 410 K+ -> e+ nu e+e- and 2679 K+ -> mu+ nu e+e- events including 10% and 19% background. The branching ratios were measured to be...

A new measurement of K+(e4) decay and the s-wave pi-pi-scattering length a00 (2001)

Pislak, S., Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D. R., Cheung, N., ...

A sample of 400000 events from the decay K+->pi+pi-e+nu(e)(K(e4)) has been collected in experiment E865 at the Brookhaven AGS. The analysis of these data yields new measurements of the K(e4)...

Search for Lepton Flavor Violation in $K^+$ Decays (2000)

Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D., Cheung, N., Dhawan, S., ...

A search for lepton flavor violating decays, \kmmp, \keep, \kpem, \kmep and \pizem, was performed using the data collected in E865 at the Brookhaven Alternating Gradient Synchrotron. No signal was...

An Improved Limit on the Rate Of Decay K+ -> pi+ mu+ e- (2000)

Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D. R., Brown, D. N., Cheung, N., ...

The experiment E865 at BNL places an upper limit on the branching ratio for the decay K+ -> pi+ mu+ e- of 3.9x10^-11 (90% C.L.). Along with with other results this yields a combined upper limit on...

A New Measurement of the Rare Decay $K^+\to \pi^+ \mu^+ \mu^-$ (1999)

Ma, H., Appel, R., Atoyan, G. S., Bassalleck, B., Bergman, D., Cheung, N., ...

More than 400 $K^{+}\to\pi^{+}\mu^+\mu^-$ events were observed in a rare $K^+$ decay experiment at the AGS. Normalized to the $K^{+}\to\pi^{+}\pi^+\pi^-$ decay, the branching ratio is determined to...

Are the production and decay of a resonance always independent? (1998)

Lichard, P

The widely accepted assumption that the decay of a resonance proceeds independently of its production, quantitatively expressed as a factorizing formula for the differential cross section in the...
