    abstract = "The ratio of the branching fractions for pp→K+K- and pp→π+π- was determined with the CPLEAR detector, by stopping antiprotons in a gaseous hydrogen target at 15 bar pressure. It was found to be BR(K+K-)/BR(π+π-)=0.20 5± 0.016. The fraction of P-wave annihilation at rest at this target density was deduced to be (38±9)%. © 1991."
