\begin{align}
    \sum_{e\in abzbb}x_{p}-l_p\sum_{e\in abdab}x_{p}=3
\end{align}

enter image description here Since my abdab is so big, it separates the l_p so much from the summation. What I would like is the following: it should be close, but it shouldn't depend on the size of whatever goes in the summation starting sum. enter image description here

From above, instead of abdab we have just a, but I want the same distance regardless of what is underneath.

Is this possible?

With mathtools loaded (needless to load amsmath in this case):

\begin{align}
    \smashoperator{\sum_{e\in abzbb}}x_{p}-l_p\smashoperator{\sum_{e\in abdab}}x_{p}=3
\end{align}
