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…
Analysis of LIGO data for gravitational waves from binary neutron stars
The LIGO Scientific Collaboration, B. Abbott
We report on a search for gravitational waves from coalescing compact binary systems in the Milky Way and the Magellanic Clouds. The analysis uses data taken by two of the three LI…
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…
