What if the Large Hadron Collider Finds Nothing Else?

In my last post, I expressed the view that a particle accelerator with proton-proton collisions of (roughly) 100 TeV of energy, significantly more powerful than the currently operational Large Hadron Collider [LHC] that helped scientists discover the Higgs particle, is an obvious and important next steps in our process of learning about the elementary workings of … Read more

Visiting the University of Maryland

Along with two senior postdocs (Andrey Katz of Harvard and Nathaniel Craig of Rutgers) I’ve been visiting the University of Maryland all week, taking advantage of end-of-academic-term slowdowns to spend a few days just thinking hard, with some very bright and creative colleagues, about the implications of what we have discovered (a Higgs particle of … Read more

Strings: History, Development, Impact

Done: All three parts of my lecture for a general audience on String Theory are up now… Beyond the Hype: The Weird World of String Theory (Science on Tap, Seattle, WA, September 25, 2006). Though a few years old, this talk is still very topical; it covers the history, development, context and impact of string … Read more

SEARCHing for New Particles on Long Island

Greetings from Stony Brook’s Simon’s Center, and the SEARCH 2013 workshop. (I reported on the SEARCH 2012 workshop here, here, here and here.) Over the next three days, a small group (about 50) of theoretical particle physicists and experimentalists from ATLAS and CMS (two of the experiments at the Large Hadron Collider [LHC]) will be … Read more

Conclusion of the Higgs Symposium

By almost all measures, the Higgs Symposium at the University of Edinburgh, as part of the new Higgs Centre for Theoretical Physics, was a great success.  The only negative was that Professor Peter Higgs himself had a bad cold this week, and had to cancel his talk, as well as missing the majority of the talks by others.  Obviously all of us in attendance were very disappointed not to hear directly from him, and we wish him a speedy recovery.

Other than this big hole in the schedule, the talks given at the symposium seemed to me to form a coherent summary of where we are right now in our understanding of the Higgs field and particle.  They were full of interesting material, and wonderfully complementary to one another.  This motivates me to try to provide, for non-experts, some future articles on what the conference attendees had to say.  But to write such articles well takes time.  So for now, here’s the quick version summarizing the last few talks, along the lines of the summaries I wrote (here and here) of the earlier talks.  The slides from all the talks are posted here.

Here we go:

It’s (not) The End of the World

The December solstice has come and gone at 11:11 a.m. London time (6:11 a.m New York time). That’s the moment when the north pole of the Earth points most away from the sun, and the south pole points most toward it. Because it’s followed by a weekend and then Christmas Eve, it marks the end … Read more

Quick Post: More on Extra Dimensions and Gravity

Quick post today: First, there were rumors about the Higgs particle search on Monday that got a lot of attention.  Caveat emptor: the experimentalists can’t possibly have their data in presentable form yet, so the rumors can’t be correct in every detail.   But if you are interested in a reasonable analysis of what the rumors … Read more

Tying Off Loose Ends

Reminder: New York, Saturday June 16th at 2pm, I’ll be giving a public lecture (click here for details): THE EINSTEIN OBSESSION: SCIENCE, MYTH AND PUBLIC PERCEPTION. I’ve been doing a little work on my extra dimensions articles, adding one that describes how we know experimentally that the ordinary particles we’re made of (and most of … Read more
