PS: Just looking over the paper I found that the references are for my 
taste not in a reasonable style or incoherent (I compared to our last 2 
pubs, lumi and psi', and found it ok there):

As an example I would write:

M.J. Leitch et al., Phys. Rev. Lett. 84 (2000) 3256.

in detail:

- et al. (and not et al)
- after authors a ',' as you do it in 1, 2, 10, .. 
- I do not see why anything (except for a title which you do not quote 
anyway) should be in italics (I know that there are some bib-styles which 
offer that, but I see no good reason).
- If the year is put into brackets I think one can omit the ',' before.
- did you make sure that always the abbreviation dor does not cause a 
longer space as for the end of a sentence (looked sometimes like that)?
- in 2. is a 'G' too much: G. Rudolphi G  

--> Sorry for the confusion about the list of references. It is my fault: 
--> I took the EJP template instead of EPJC, and this only got corrected
--> before I made this last distribution, without a careful final check.
