### Reduce space before and after a sum in an equation

Hello
I need to reduce the space before and after the sum in an equation to be placed within a text. This is the equation
  \documentclass[12pt]{article}  \begin{document}  texte.....$\alpha = \displaystyle\sum_{j=UCL+1}^{n}BIN(j, n, p_0)$....texte  \end{document}

I used \! to reduce space but I didn't get good results.

Use \mathclap from mathtools (part of the mh bundle).
\documentclass[11pt]{article}\usepackage[T1]{fontenc}\usepackage{mathtools}  % loads »amsmath« \begin{document}   $\alpha =\sum_{\mathclap{j=UCL+1}}^{n} BIN(j,n,p_0)$\end{document}
