[g13] MENU proceedings draft (rather urgent-ish)

[Daria Sokhan]

Hi Pawel and everyone,

Many thanks for you suggestions and apologies for the delay replying
-- lack-of-internet issues at the summer school yesterday and me in
transit on wifi-less trains all day today!

1. I agree the polarisation observable programme is more general than
a search for specific resonances,  and I have included your
suggestions in the modified version of the paper, which can be found
at:

http://www.jlab.org/~daria/Daria_MENU_proceedings.pdf

However, since it's a proceedings paper, I am trying to summarise what
I had in the talk. Also, it's only four pages long, and attempting to
present tid-bits of lots of different results in that space means I
have to be concise in the text.

2. Agreed on the idea of presenting just a few "example" plots -- I've
cut out quite a few.

The paper finally fits on four pages, but it's a very very tight fit
(I don't have a single spare line) -- so if anyone feels that I need
to add something else, I would be grateful if you could also suggest
what I could cut out! Else it probably won't fit.

Many thanks,
Daria
