The First Version of the Higgs FAQ

Taking advantage of our day and a half off from physics talks in Grenoble, I’ve written the answers to some questions that are often asked (or should be asked) about the Higgs particle.  I had planned to do a very careful job of explaining what the Higgs particle is all about — and eventually I … Read more

ATLAS and CMS report on Higgs decaying to W particles

ATLAS reports that they have excluded Higgs with mass of 158-186 GeV but see an excess of between 2 and 3 standard deviations in the range 130-150 or so. CMS reports exclusion of 150-183 but they see some excess in the same region of 130-150 or so, not quite as large, more like 1-2 standard … Read more

Quick update from Grenoble

Greetings from Grenoble, and the EuroPhysics conference.  There’s so much data being described, and there are so many simultaneous talks, that it is hard to make sure I’m getting all of the new information.  And there’s a huge amount of news, which will take a while to summarize. Before I do, I should say that … Read more

A long-expected [and not-so-exciting] particle finally observed

No less than Fox News reports that Fermilab has found a new particle!  And it’s true, but this is one of those places where the word “particle” is not descriptive.  This is a new [but totally expected!] HADRON, a particle made from other known particles — quarks, antiquarks and gluons.

Some thoughts on why there’s so much Tevatron news.

Greetings from Grenoble and the European Physical Society conference!  Lots of new data to review!  I’ll have more to say on that over the next days. Meanwhile, you might be wondering, as have been many particle physicists, why the Tevatron experiments CDF and DZero are seeing so many deviations from the Standard Model recently.  Here’s … Read more
