A study has been performed of the reaction p̅ p⃗4K± using in-flight antiprotons from 1.1 to 2.0 GeV/c incident momentum interacting with a hydrogen jet target. The reaction is dominated by the production of a pair of φ mesons. The p̅ p⃗φφ cross section rises sharply above threshold and then falls continuously as a function of increasing...
