Hat covers the whole expression. – Suman Nov 29 '13 at 07:48

@Federico It is not a duplicate of the suggested question. OP wants hat after, not over the whole expression. – Przemysław Scherwentke Nov 29 '13 at 09:37

@PrzemysławScherwentke that it is not what I understand from its comment above: "Hat covers the whole expression" – Federico Nov 29 '13 at 09:46

Sorry @Federico. I wanted to mean after the whole expression. – Suman Nov 29 '13 at 14:08

I understand, that it is like some kind of Fourier transform of the whole expression. An alternative version added.
\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
\newcommand{\Sel}{\operatorname{Sel}}
\[
\Sel_{E}^{\Sigma_0}(\mathbb{Q}_\infty)_p{}\widehat{}
\]
But probably better
\[
(\Sel_{E}^{\Sigma_0}(\mathbb{Q}_\infty)_p)\,\widehat{}
\]
\end{document}

If a really wide "hat" symbol that should cover the entire expression is what you're after, you may want to look into using the Mathtime Professional 2 (mtpro2) package. The full package isn't free of charge, but its "lite" subset, which is all that's needed to create a superwide hat symbol, is indeed free.
\documentclass{article}
\usepackage{amsmath,amssymb}
\newcommand{\Sel}{\operatorname{Sel}}
\usepackage[lite]{mtpro2}
\begin{document}
\begin{equation*}
\widehat{\Sel_{\mathrm{E}}^{\Sigma_0}(\mathbb{Q}_\infty)_p}
\end{equation*}
\end{document}

you write
Hat covers the whole expression
Do you mean something like this?
\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
\newcommand{\Sel}{\operatorname{Sel}}
\begin{equation*}
\widehat{\Sel_{E}^{\Sigma_0}(\mathbb{Q}_\infty)_p{}}
\end{equation*}
\end{document}
