I have no idea Fred, but finding Xi baryons is not nearly as much a news as finding the Higgs… I guess it did not cross the line of media interest.

Just curious, but why don’t we have the media hoopla that accompanied some recent events that were considered rumorish? I googled news and found several related articles but many copies of the same.

Hi Kea, yes, as Gordon explains, the black parts are the additional error due to the quadrature of stat + systematics, the inner bar is only statistical.

Gordon, I think the authors wanted to put together the all-hadronic decay mode (which, as you’ve seen, does not quote a mass yet, mainly because of different systematics from the two-track SVT trigger) with the other result before publishing. As always, CDF acts as if we are the only ones doing this business

Yep Louise, filling the gaps in the quark model gives a sense of understanding the structure of matter few other things do.

Cheers,
T.

A new baryon is very exciting!

Sys vs stat error. So, I have to ask, and sorry if this is a bit snarky (it isn’t meant to be) — but why didn’t CDF submit a paper for this? What part of the analysis is missing?

What’s with the black bits on the D0 (er, rather large) error bars? OK, maybe I should look at their paper….
