Many discussions:

- Can the strong CP problem be resolved averaging over all theta angles in some way?

Integrating all theta in the path integral seems to solve the problem but one probably gets

a non-local theory and completely wrong hadronic physics...

Still confusing how to understand the effects of theta from local physics: integrating over

topologically trivial configurations will not change the fields in a region of order 1/GeV that should

be relevant for confinement. Help!

- sandpile models: interesting and generic condensed matter systems but are they good for something in particle physics?

Eternal inflation? Interesting connection with logarithmic quantum field theories in 2D. Worth exploring further.

- running of alphaS: are experimental papers wrong? How can they extra alphaS with 5% precision given the montecarlo uncertainties?

Thought axigluons would contribute to the running like gluons but in the end the effect cancel out. Ouch:-(

- Is AdS/CFT natural? I thought I gave a positive answer 10 years ago..
