A search for the H0 dibaryon
MetadataShow full item record
The H Dibaryon is a theoretical six quark (uuddss) s-wave flavor-color singlet with I=0, Y=0, B=2, S=-2 and spin-parity Jπ =0+ . Proposed in 1977 by Jaffe, the H has been the subject of more than thirty experiments. Experiment 896 at the Brookhaven National Laboratory Alternating Gradient Synchrotron searched for the H with an Au beam and an Au target. The experiment utilized a Silicon Drift Detector Array in an effort to detect the H via the H p− → Σ decay channel. This search is sensitive to weakly decaying H Dibaryons with lifetimes as small as 4 cm.
