First observation of the decay K+ -> e+ nu mu+ mu-
H. Ma, R. Appel, G. S. Atoyan +23
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}…
An Improved upper limit on the decay K^+ -> pi^+ mu^+ e^-
Aleksey Sher, R. Appel, G. S. Atoyan +24
Based on results of a search for the lepton-family-number-violating decay with data collected by experiment E865 at the Alternating Gradient Synchrotron of Bro…
New, high statistics measurement of the K+ -> pi0 e+ nu (Ke3) branching ratio
A. Sher, R. Appel, G. S. Atoyan +25
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…
High statistics measurement of Ke4 decay properties
S. Pislak, R. Appel, G. S. Atoyan +25
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 collecte…
Experimental Study of the Radiative Decays K+ -> mu+ nu e+e- and K+ -> e+ nu e+e-
A. A. Poblaguev, R. Appel, G. S. Atoyan +23
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 (2.4…
A new measurement of K+(e4) decay and the s-wave pi-pi-scattering length a00
S. Pislak, R. Appel, G. S. Atoyan +24
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…
Search for Lepton Flavor Violation in Decays
R. Appel, G. S. Atoyan, B. Bassalleck +25
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 Synchrotro…
An Improved Limit on the Rate Of Decay K+ -> pi+ mu+ e-
R. Appel, G. S. Atoyan, B. Bassalleck +33
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 combine…
A New Measurement of the Rare Decay
H. Ma, R. Appel, G. S. Atoyan +25
More than 400 events were observed in a rare decay experiment at the AGS. Normalized to the decay, the branching ratio is determin…

R. Appel
A large low-background sample of events (10300) has been collected for the rare decay of kaons in flight K+ -> pi+ e+ e- by experiment E865 at the Brookhaven AGS. The decay product…
Measurement of the Charged Multiplicity of Events
The SLD Collaboration
Using an impact parameter tag to select an enriched sample of events, we have measured the difference between the average charged multiplicity of $Z…
