need to be re-analyzed

Dozens of theoretical papers

(some of them most ingenious)

explain the `signal’ positron excess

~ 2 theoretical papers

discuss the background

Page 22: Test 1

[1] Katz et al., arXiv:0907.1686

“The radiative positron energy loss...is not understood theoretically”

“The claims that the positron fraction measured by PAMELA requires new primary positron sources are

based on assumptions not supported by observations”

[2] Serpico, arXiv:1108.4827

The only “theoretical” argument is to assume that ...there is no mechanism [consistent with cosmic ray astrophysics...] to explain the PAMELA data

Page 23: Test 1

If you use a background Monte Carlo [e.g. GALPROP]that you have not undestood[and should not blindly trust]

you are doing a disserviceto the faithful community of poor innocent theorists + ...

Universes with the same average density need NOT have the same
