Abstract:

The width of the D *+ was measured by studying the distribution of the energy release in D *+→D 0π + followed by D 0→K -π + decay. For the smallest statistical uncertainty, Γ(D *+)=96±4±22 keV, was obtained.

Abstract:

An attempt was made to search for new physics using LS dilepton events in association with two or more jets and ∄ T in pp̄ collisions at s=1.8 Te V. Within a framework of constrained MSSM (five degenerate squarks, M q̃- ≳ 0.9M g̃), for small tanβ, mass limits of M g̃ > 168 GeV/ c 2 were set for M g̃ >> M g̃, and M g̃ > 221 GeV/c 2 for M g̃ ≃ M g̃, both with small variation as a function of μ.
