Abazov, V. M.; Abbott, B.; Abolins, M.; Acharya, B. S.; Adams, M.; Adams, T.; Aguilo, E.; Ahsan, M.; Alexeev, G. D.; Alkhazov, G.; Alton, A.Made available in DSpace on 2022-04-28T20:47:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-12-05; Science and Technology Facilities Council; We report the observation of the doubly strange b baryon Ωb- in the decay channel Ωb-→J/ψΩ-, with J/ψ→μ+μ- and Ω-→ΛK-→(pπ-)K-, in pp̄ collisions at s=1.96TeV. Using approximately 1.3fb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider, ...

No. of bitstreams: 0 Previous issue date: 2010-11-05; Science and Technology Facilities Council; We report the results of a search for R parity violating (RPV) interactions leading to the production of supersymmetric sneutrinos decaying into eμ final states using 5.3fb⊃-1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Coll...
Search for single vectorlike quarks in pp̄ collisions at √s=1.96TeV
Abazov, V. M.; Abbott, B.; Acharya, B. S.; Adams, M.; Adams, T.; Alexeev, G. D.; Alkhazov, G.; Alton, A.; Alverson, G.; Alves, G. A.; Ancu, L. S.Made available in DSpace on 2022-04-28T22:02:15Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-02-22; National Science Foundation; We present a search for hypothetical vectorlike quarks in pp̄ collisions at √s=1.96TeV. The data were collected by the D0 detector at the Fermilab Tevatron Collider and correspond to an integrated luminosity of 5.4fb-1. We select events with a final state composed of a W or ...
