Can the above \zeta and \sum symbol be produced exactly in latex? If yes what package to use? Kindly help.
Thanks.
EDIT: This is not a duplicate. I am looking for a math typeface which gives summation symbol exactly as show in the image above.
\zeta and \sum symbols can be reproduced in LaTeX, if you already know their name? If this code doesn't solve your problem, please edit your question and be more specific:
\documentclass{book}
\usepackage{amsmath, amssymb}
\begin{document}
\[
-\frac{{\zeta}^{\prime}(s)}{\zeta(s)} = \sum_{m\geq 1}\frac{\Lambda(n)}{{n}^{s}}
\]
\end{document}
Edit:
As Mico said, this is the result with newtxmath package:
\documentclass{book}
\usepackage{newtxmath}
\DeclareMathOperator*{\mysum}{\text{\raisebox{-2pt}{\scalebox{2}{$\Sigma$}}}}
\begin{document}
\[
-\frac{{\zeta}^{\prime}(s)}{\zeta(s)} = \sum_{m\geq 1}\frac{\Lambda(n)}{{n}^{s}}
\]
\end{document}
Eventually, you could create your own math operator.
Second edit
As you correctly pointed out, my first solution (\mysum) doesn't become smaller when it was not in display style.
I have created another command (\mynewsum) that scales according to the size of the \sum operator.
If you prefer my first solution for display style, you can use a mix of the previous two (see \myfinesum).
\documentclass{book}
\usepackage{amsmath, amssymb}
\usepackage{array}
\usepackage{booktabs}
\renewcommand*{\arraystretch}{3}
\usepackage{graphicx}
\usepackage{scalerel}
\DeclareMathOperator*{\mysum}{\raisebox{-2pt}{\scalebox{2}{$\Sigma$}}}
\DeclareMathOperator*{\mynewsum}{\scalerel*{\Sigma}{\sum}}
\DeclareMathOperator*{\myfinesum}{%
\mathchoice
{\raisebox{-2pt}{\scalebox{2}{$\Sigma$}}}%
{\scalerel*{\Sigma}{\sum}}%
{\scalerel*{\Sigma}{\sum}}%
{\scalerel*{\Sigma}{\sum}}
}

\myfinesum everywhere, please look at this command in my last edit.

\myfinesum when i give the command \renewcommand{\sum}{\myfinesum} why does it show an error?

\sum with a command which uses \sum. You have to save the old \sum under another name and then use this name in \renewcommand, see here: https://tex.stackexchange.com/q/47351/101651.

pdftex? Is it really engine specific? – cfr Apr 24 '17 at 01:29newtxmathpackage. (Couple it with thenewtxtextpackage.) Its glyphs for\zetaand\sumcome pretty close to those in the screenshot you posted. – Mico Apr 24 '17 at 05:27\sumsymbol. (The symbol's shape is OK, though, right?) – Mico Apr 24 '17 at 05:35
