# Is this an error in Srednicki?

Hi,

On p104 of Srednicki's QFT, he does an integral in closed form, equations 14.43 and 14.44. I just ran the calculations for this in Mathematica, and I get his answer exactly except for my constants $$c_1=4-\pi\sqrt{3}$$ and $$c_2=4-2\pi\sqrt{3}$$.

The mathematica code I used to generate this was:

Then collecting the terms in k^2 and m^2, you find the constants I posted above, rather than the very similar but different Srednicki ones.

It's not listed on his errata page if this is an error, perhaps I am missing something? just seems very close, to not be correct.

Oh sorry, I literally saw the second I pressed send, that he also subtracts a $$\tfrac{1}{12}\alpha (k^2+m^2)$$ in 14.43 that I left off.
