Observation of high mass mu /sup +/ mu /sup -/ pairs at the ISR

Observation of 16 mu /sup +/ mu /sup -/ pairs of invariant mass greater than 2.7 GeV/c/sup 2/ in the reaction pp to mu /sup +/ mu /sup -/+anything at square root s=52 GeV at the CERN Intersecting Storage Rings (ISR) is reported. These events can be interpreted as originating from J(3.1) decay into m...

Descripción
Sumario:Observation of 16 mu /sup +/ mu /sup -/ pairs of invariant mass greater than 2.7 GeV/c/sup 2/ in the reaction pp to mu /sup +/ mu /sup -/+anything at square root s=52 GeV at the CERN Intersecting Storage Rings (ISR) is reported. These events can be interpreted as originating from J(3.1) decay into mu /sup +/ mu /sup -/. Their p/sub T/ distribution suggests a hadronic production. The cross section for J production is given and compared to the cross section for single lepton production. It is concluded that J(3.1) production cannot fully account for single lepton production.
