DZero publishes 500th paper

On July 27, DZero submitted two papers to Physical Review D: “Studies of X(3872) and ψ(2S) production in pp collisions at 1.96 TeV” and “Study of the normalized transverse momentum distribution of W bosons produced in pp collisions at √s = 1.96 TeV.” The first paper, with primary authors Alexey Drutskoy (Lebedev Institute Moscow) and Daria Zieminska (Indiana University), was published on Oct. 13. The second paper, with primary authors Chen Wang (University of Science and Technology of China) and Matthias Schott (University of Mainz), was accepted for publication on Dec. 9.

These two papers constitute a tie for the 499th and 500th publications by the DZero collaboration. Although this is not a record number of papers for a collaboration, it is a noteworthy accomplishment, and DZero has joined a select club. It has been a long journey that began with the first full-collaboration paper in Nuclear Instruments and Methods on Jan. 1, 1993, “Beam Tests of the DØ Uranium Liquid Argon End Calorimeters,” with primary author John Womersley, director-general the European Spallation Neutron Source. The authors of the other publications deserve equal congratulations.

While there will still be more publications (one has just been submitted as we write), this milestone deserves recognition and gives us an opportunity to extend our congratulations and thanks to the roughly 1,500 members of the collaboration over the 38 years of its existence. It is a privilege to be a part of a collaboration that has influenced the evolution of our understanding of the physical world in so many ways.

Dmitri Denisov of Brookhaven National Laboratory and Paul Grannis of Stony Brook University are the DZero spokespersons. Bob Hirosky of the University of Virginia and Boris Tuchming of CEA-Saclay are the DZero physics coordinators.
