Observation and Properties of the X(3872) Decaying to J/psi pi+ pi- in p-p(bar) Collisions at sqrt(s) = 1.96 TeV
D0 Collaboration, V. M. Abazov
We report the observation of the X(3872) in the J/psi pi+pi- channel, with J/psi decaying to mu+mu- in p-p(bar) collisions at sqrt(s) = 1.96 TeV. Using approximately 230 pb^-1 of d…

Report of the Working Group on Precision Measurements
R. Brock, J. Erler, Y. K. Kim +9
In the first part of this report, we discuss the prospects for measuring the W mass and width in Run II. The basic techniques used to measure M_W are described and the statistical,…
