I would like each of you to have the opportunity to explore an effective field theory subject on your own and give a short presentation to the rest of the class. The goal of your presentation is to teach it to your fellow students at a level they can understand without having done background reading. The subject of effective field theory is rich and diverse, and far broader than I will be able to cover in one semester. The presentations will create an opportunity for you to learn about additional subjects beyond those in lecture. They will take place on a date near the end of the semester. (If someone has a strong preference they may substitute additional problem sets in place of a presentation.) Below is a list of possible topics. If you prefer you are free to come up with your own. For each of the ones below a reference to start you off is listed. I imagine that taken far enough some of your projects could be turned into research that leads to a publishable paper (though for the class you are only required to report on research from the literature).

A Lattice QCD EFT -- Finite Volume or Twisted Mass

The instructor would choose appropriate references.

A continuation of any topic discussed in lecture not already mentioned above (HQET, NRQCD, SCET, Chiral perturbation theory for matter fields, electroweak Hamiltonian, NN effective theory, NRQCD, ...). A proposed topic must go beyond what we discuss in lecture.

A topic of your choosing (with instructor's approval). I'm well aware that this list is far from complete and some of you will surely come up with a topic you find more interesting than those I have listed. For example I didn't mention any EFT topics from beyond the standard model besides the MSSM and extra dimension models.
