Description

The extremely rare decay K+ -> pi+ neutrino anti-neutrino has been studied for the last 20 years with the E787 and E949 experiments and the high-intensity proton beam of the AGS accelerator at Brookhaven National Laboratory. The E949 experiment previously reported results above the K+ -> pi+pi0 peak, in the pion momentum region [211,229] MeV/c {Phys.Rev.Lett.93:031801(2004); Phys.Rev.D77:052003(2008)}. E949 has recently reported results below the K+ -> pi+pi0 peak, in the pion momentum region [140,199] MeV/c, {Phys.Rev.Lett.101:191802(2008);Phys.Rev.D79:092004(2009)}. A total of seven candidates of this very rare process have been identified. This talk will describe the experiment and these results.
