    Standard Model: Lagrangian vs. Hamiltonian

    I was wondering: why is the SM always written with a Lagrangian? Couldn't you just as well write it with a Hamiltonian? The way I understand, the Lagrangian gives me the kinetic energy minus the potential energy (basically a measure for the "free energy", though not in the thermodynamical...

    Standard Model as TOE? Arguments Against & Need for More Particles

    Which are the arguments against considering the possibility of the Standard Model as a TOE. Why do we need more particles or more degrees of freedom? It lacks, of course, a mechanism to get the SM from geometric considerations, or to get geometry from the SM. But it is almost a minor nuissance.

    Introduction to Standard Model: presentation(s) requested

    Hi all, I have been asked to give an informal presentation on the Standard Model to some chemists (note that this is not really my field of expertise ). I was wondering if there are some good (powerpoint) presentations out there that I could use to base mine on. That would save me a lot of...

    Looking for good overview (book or paper) of standard model

    Hi all, I've decided to read up on particle physics in my spare time for my own edification, but I've had some trouble locating a good textbook/survey paper with a succinct, technical and up-to-date description of the standard model. The text or two that i do have on hand were published in the...

    Contradicting Physics Beyond the Standard Model

    http://www.lns.cornell.edu/spr/2003-10/msg0055587.html I think its a stroke of good luck that the SSC was canceled since otherwise it might have produced data that contradicted all the physics beyond the Standard Model that physicists now take for granted, and we would have to throw out...

    Noncommutative geometry and the standard model

    I hate to risk additional distraction when we have so much thoughtful discussion---and add an additional thread when there are several good ones going, but I just came across a 15 October post at arxiv which I want to pass along, should anyone be interested. It is an 11-page article...

    Standard Model from Intersecting Branes?

    This is currently a hot topic, and I hope to get some discussion of it from our resident experts on stringy subjects. To start off here's a recent paper, maybe not the greatest but typical and fairly wide-ranging. If you know a better one, or a turorial on the subject why not favor us with a...
