At last I succeeded!

Firstly, let

In[14]:=
f[o_, m_] := MeijerG[{{1}, {}}, {{-2^(-1), 1/2}, {0}}, o^2/(4*m^2)]

here is the definition...

http://functions.wolfram.com/HypergeometricFunctions/MeijerG/02/0006/

but it doesn't seem to say what the contour is



Here is a description including the contour

http://mathworld.wolfram.com/MeijerG-Function.html

from that description, it looks like you should try
Integrals and Series, Vol. 3: More Special Functions by Prudnikov et al
