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...
Search for Doubly Charged Higgs Boson Pair Production in the Decay to μ+μ+μ-μin...
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...
Genotypic and pathogenic diversity of Colletotrichum sublineola isolates from S...
Mizubuti, E. S. G.; Xavier, K. V.; Queiroz, M. V.; Chopra, S.; Vaillancourt, L.Anthracnose caused by Colletotrichum sublineola is an important disease of cultivated sorghum (Sorghum bicolor) worldwide. Anthracnose is also common on the ubiquitous wild sorghum relative Johnsongrass (S. halepense). Analysis of repetitive molecular fingerprinting markers revealed that isolates of C. sublineola from both hosts in the southeastern United States were genotypically diverse, with relatively few h...
