Just as a side remark...
Say,
In[8]:=
o = HypergeometricPFQ[{1}, {1/2 + k/2, 1 + k/2}, (-4^(-1))*t^2*w^2]
Out[8]=
HypergeometricPFQ[{1}, {1/2 + k/2, 1 + k/2}, (-(1/4))*t^2*w^2]
Then e.g.
In[25]:=
FullSimplify[FunctionExpand[o /. Thread[{k, t, w} -> {1/2, 1/3, 2}]]]
Out[25]=
(1/2)*Sqrt[3*Pi]*(Cos[2/3]*FresnelC[2/Sqrt[3*Pi]] + FresnelS[2/
Sqrt[3*Pi]]*Sin[2/3])
