Abazov, V. M.; Abbott, B.; Abolins, M.; Acharya, B. S.; Adams, D. L.; Adams, M.; Adams, T.; Agelou, M.; Agram, J. L.; Ahmed, S. N.; Ahn, S. H.Made available in DSpace on 2022-04-28T19:57:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2005-02-04; We report the results of a search for supersymmetry (SUSY) with gauge-mediated breaking in the missing transverse energy distribution of inclusive diphoton events using 263 pb-1 of data collected by the DO experiment at the Fermilab Tevatron Collider in 2002-2004. No excess is observed above the backgro...
Measurement of the Bs0 lifetime in the exclusive decay channel Bs0 → J/ψφ
Abazov, V. M.; Abbott, B.; Abolins, M.; Acharya, B. S.; Adams, D. L.; Adams, M.; Adams, T.; Agelou, M.; Agram, J. L.; Ahmed, S. N.; Ahn, S. H.Made available in DSpace on 2022-04-28T19:57:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2005-02-04; Using the exclusive decay Bs0 → J/ψ (μ+μ-)φ (K+K-), we report the most precise single measurement of the Bs0 lifetime. The data sample corresponds to an integrated luminosity of approximately 220 pb-1 collected with the DO detector at the Fermilab Tevatron Collider in 2002-2004. We reconstruct 337 signa...

No. of bitstreams: 0 Previous issue date: 2005-06-10; Correlations in the azimuthal angle between the two largest transverse momentum jets have been measured using the D0 detector in pp̄ collisions at a center-of-mass energy s=1.96TeV. The analysis is based on an inclusive dijet event sample in the central rapidity region corresponding to an integrated lum...
Observation and properties of the X(3872) decaying to J/ψπ+π- in pp̄ collisions...
Abazov, V. M.; Abbott, B.; Abolins, M.; Acharya, B. S.; Adams, D. L.; Adams, M.; Adams, T.; Agelou, M.; Agram, J. L.; Ahmed, S. N.; Ahn, S. H.Made available in DSpace on 2022-04-29T00:12:35Z (GMT). No. of bitstreams: 0 Previous issue date: 2004-10-15; The discovery of a new particle, X(3872) by the Belle collaboration in the decay mode B±→ XK± (X→ J/ψπ+π - was discussed. It was found that the mass of the X(3872) was measured to be 3872.0 ± 0.6(stat) ± 0.5 (syst) MeV/C2. The X(3872) particle were observed in approximately 230 pb-1 of data with a signi...

Abazov, V. M.; Abbott, B.; Abolins, M.; Acharya, B. S.; Adams, D. L.; Adams, M.; Adams, T.; Agelou, M.; Agram, J. L.; Ahmed, S. N.; Ahn, S. H.Made available in DSpace on 2022-04-29T00:13:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2004-10-01; The pair production of doubly charged Higgs bosons in the decay to μ+ μ+ μ- μ- in pp̄ Collisions was investigated. It was observed that the total signal efficiency for the event selection was (47.5±2.5)% and does not depend on the mass of the doubly charged Higgs boson in the studied mass range. Data an...
