ORKA: The Golden Kaon Experiment

ORKA is a proposed experiment to measure the K+→μ+νν¯ branching ratio with 5% precision using the Fermilab Main Injector high intensity proton source. The detector design is based on the BNL E787/E949 experiments, which detected seven K+→μ+νν¯ candidate events. Two orders of magnitude improvement in...

Description
Summary:ORKA is a proposed experiment to measure the K+→μ+νν¯ branching ratio with 5% precision using the Fermilab Main Injector high intensity proton source. The detector design is based on the BNL E787/E949 experiments, which detected seven K+→μ+νν¯ candidate events. Two orders of magnitude improvement in sensitivity relative to the BNL experiments comes from enhancements to the beam line and the detector acceptance. Precise measurement of the K+→μ+νν¯ branching ratio with the same level of uncertainty as the well-understood Standard Model prediction allows for sensitivity to new physics at and beyond the LHC mass scale.
