Jim Linneman (MSU) on DZero results

(From Mich. State Univ)



  • B_s --> J/psi phi -- not fitting the SM well, prob. is 6% of being SM. hint of new fizz..?

  • Direct CPV in B+- --> J/psi K

  • H events: looking for 1 in 1e12 events..!

  • Acoplanarity in qq -> Z* -> ZH is from no spin coupling between the Z and H

  • One plot shows the curve at 160 GeV nearly meeting the 2 sigma bar, with 2.4ifb collected -- 2 more ifb is in the can, so once that's done, the limit will at 160 go *below* the SM 2 sigma line.. kind of cool, i didn't realize how close they are to limits. they really have a real chance at this, the next 2 years..!

  • Exotic searches: stops, etc.

  • XD

  • Push for making the data more usable for others outside expt, discussion a bit of Bruce Knuteson's work -- about 10 people used it, 5 within D0.
