Current quark mass and g-2 of muon and ee-->\pi\pi
Based on an effective chiral theory of mesons the dependences of
mixing and the vertex on are found. The
form factor of pion agrees with data in both space- and time-like regions. CVC
is satisfied. The values of g-2 of muon from channel are calculated in
the range of .Comment: 14 pages anf three figures 14 pages and three figure
A short note on small deviations of sequences of i.i.d. random variables with exponentially decreasing weights
We obtain some new results concerning the small deviation problem for
and , where and are i.i.d.
non-negative random variables. In particular, the asymptotics is shown to be
the same for and in some cases.Comment: Revision, 13p, to appear in: Statist. Probab. Let
