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…
