I'm trying to find the following limit:



$$ undersetn to inftytextrmlim
fracsqrt[3]n2^n n! sqrtpi int_sqrt2n+1^inftytextrmH^2_n(x) e^-x^2dx $$



Where H is a hermite polynomial (the physicist kind).
I'm pretty sure the limit is



$$ frac13^2/3Gamma^2(1/3) $$



This is based on an asymptotic formula using Airy functions.



Any thoughts on how to find the limit?



If it is any help, the limit can also be represented as



$$ undersetnrightarrow inftytextrmlimfracsqrt[3]n2 cdot n!fracd^n dx^n left .fractextrmerfcleft ( sqrttfrac1-x1+x sqrt2n+1right )1-x right |_x=0 $$
