Compact Muon Solenoid (CMS) has observed the xi baryon by looking for events containing both lambda baryons and pi mesons. If these two particles are observed and came from a single parent particle, we expect to see a narrow peak in our data. This measurement used data taken in December, including th...
Fermilab physicists discover "triple-scoop" baryon Three-quark particle contains one quark from each family. Physicists of the DZero experiment at the Department of Energy's Fermi National Accelerator Laboratory have discovered a new heavy particle, the b (pronounced "zi...
Title: Observation of an excited Xi(b) baryon Authors: CMS Collaboration The observation of an excited b baryon via its strong decay into Xi(b)^- pi^+ (plus charge conjugates) is reported. The measurement uses a data sample of pp collisions at sqrt(s) = 7 TeV collected by the CMS experiment at the L...
