[Shape-univ] CMB/WMAP constraints on alpha

[blew]

Witam,

So, getting back to alpha, there is a nice paper 
with a nice intrduction with summary on fine structure constant evolution
from variety of experiments (see refs.)
and using WMAP 1st yr data they constrain alpha by it's
impact on recombination rate and hence power spectrum

here it is:
