PEN: a sensitive search for non-(V-A) weak processes

PEN Collaboration, D. Pocanic, L. P. Alonzi +26

A new measurement of $B_{π e 2}$ , the $π^{+} \to e^{+} ν (γ)$ decay branching ratio, is currently under way at the Paul Scherrer Institute. The present experimental result on $B_{π e 2}$ con…

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 $K^{+} \to π^{+} μ^{+} e^{-}$ with data collected by experiment E865 at the Alternating Gradient Synchrotron of Bro…

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…

New Results on Rare and Forbidden Semileptonic $K^{+}$ Decays

Peter Truoel

Experiment E865 at the Brookhaven AGS was set up primarily to search for the lepton flavour violating decay $K^{+} \to π^{+} μ^{+} e^{-}$ ( $K_{π μ e}$ ) with high sensitivity. The flexibility of…
