Breathe, BaBar, breathe

I remember a time when the fall was the quietest part of the year. You’d escape the twists and turns of the summer conference cycle, survive the post-conference fall collaboration meeting, and set your sights on the winter/spring conferences, or on the hard work of wrapping things from the summer into publications.

This isn’t your typical fall. BaBar is in the intense analysis period, almost a year ahead of schedule and with several new data sets on top of the extensive Upsilon(4S) data, which occupied the first seven years of our operations. With the unparalleled Upsilon(3S) and Upsilon(2S) data sets have come a tremendous set of new responsibilities, and at least one discovery so far [1]. I am constantly impressed with the level of dedication to physics research that my colleagues achieve, a level surpassed each month with new intensity and determination.

In every physics experiment, there comes a time when all the really hard work of securing the data pays off in an avalanche of results. I thought that BaBar had passed that point, but I was wrong. I was worried that the black hole of the LHC, sucking all of us into the frontier of the field, or sling-shotting us into new research in dark matter, dark energy, and neutrinos, would ultimately deplete Babar to the point where this would be the least interesting autumn ever.

Boy, was I wrong.

Broken symmetries

The 2008 Nobel Prize in physics has been awarded for work both  “for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics” and “for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature” [1]. The write-up of the background physics for the prize  notes the hard work of the Belle and BaBar collaborations in confirming the mixing matrix model as a complete description of CP violation in the quark system.

While many lively discussions are currently in progress about whether others should or should not have received the prize (I think the ones about the medical Nobel are more heated), the decision has been made and it’s worth taking time to reflect on the insights of the physicists awarded this prize. You can argue about the arbitrariness of awarding just three people a year a prize for work on such a rich subject as physics, and you can debate whether some people did the work first or are more deserving. These are all valid discussions. But in the process, let us not forget that what has been singled out is damn good physics.

The seminars so far: personal travelogue

I’ve concluded two of my eight seminars for September and October. So far, I am having a wonderful time, I’m meeting a lot of new colleagues in the field, and I’m getting very positive feedback both on my talk and the physics content. If you’re interested in following my travels through New England, Canada, and the Midwest, you can do so in my personal blog [1].
