Text and equation environment to have different fonts

Question

I have read this paper, and from what I saw, the font of the text looks exactly like (in fact, I think it is the same as) the mathpazo font. The font of all the equation environments, however, looks exactly like the Helvetica font. I am currently using mathpazo, but I hate how most of the notation especially the summation sign looks. I want the fonts of the text and the equation environment of my paper to look exactly like what is in the above paper. How do I make that possible? My \documentclass is article.

Welcome to TeX.SE. To find out which fonts are contained in a pdf file, just click on File -> Properties and click on the "Fonts" tab. A separate comment: Instead of asking people to download and leaf through a 200+-page pdf file, please consider editing your posting to show a (reasonably high resolution) screenshot of the a representative page that features both text and math material. — Mico, Feb 22 '20 at 16:24
It is used only for the auyhor's name, and the real font is ArialMT. The maths font seems to be Computer Modern. — Bernard, Feb 22 '20 at 16:31

The text font seems to be similar to Palatino, which can be used with the newpx package, and the math font seems to be the standard computer modern. To change only the text font, you can load the package newpxtext. For example, using the following code

\documentclass{article}
\usepackage{newpxtext}
\usepackage{amsmath,amssymb,amsthm,mathrsfs}
\theoremstyle{definition}
\newtheorem{definition}{Definition}
\begin{document}
\begin{definition}
Let \(\omega \in \mathbb{R} \setminus \{0\}\) be a constant. If \(f \in L^1(\mathbb{R}^n)\), then its \emph{Fourier transform} is \(\mathscr{F}f\) or \(\hat{f} : \mathbb{R}^n \to \mathbb{C}\) defined by
\begin{equation}
\mathscr{F}f(\xi) = \int_{\mathbb{R}^n} e^{-\omega i x \cdot \xi} f(x) dx
\end{equation}
for all \(\xi \in \mathbb{R}^n\).
\end{definition}
\end{document}

we get the definition

and this is the corresponding text from the original document:

Finally, I have been able to lay my hands on what I have been looking for all this while. It is indeed what Vincent suggested. Thank you, @Vincent. – Ujan Feb 22 '20 at 16:59

I give to Caesar what is Caesar's. Very good. – Sebastiano Feb 22 '20 at 17:05
Just a quick one. @Vincent, do you have an idea of how they colored those theorem environments and those of definitions? – Ujan Feb 23 '20 at 16:55
@Ujan Maybe with the tcolorbox package. It's certainly a good way to achieve this. – Vincent Feb 23 '20 at 17:59
I have tried that, but around the text is an outline, which I do not need. Do you have an idea about how to eliminate it? – Ujan Feb 23 '20 at 18:06

I have figured it out. Thank you. – Ujan Feb 23 '20 at 18:13
@Vincent, how do I get the colored backgrounds for the theorem and equation environments as done in the original article, please? – Ujan Aug 15 '21 at 01:24

@Ujan It can be done with tcolorbox. See this answer to remove the border around a tcolorbox. If you're having trouble achieving this, you could ask another question and someone will be able to answer with code, that might help. – Vincent Aug 15 '21 at 13:19
Thank you. It worked – Ujan Aug 15 '21 at 14:04
@Vincent, one more question, please: Looking at the paper http://www.math.ac.cn/kyry/hcc/hccteach/201512/P020160615514232188602.pdf, what paper size could that be? I know it's smaller than an A4 paper but larger than an A5 paper size. Please help. By the way, it is the same paper I previous asked a question about. – Ujan Aug 15 '21 at 23:20
I have figured it out. I think it's either a B5 or an executive paper – Ujan Aug 16 '21 at 00:16

The different font families were designed to have an harmonious, pleasing look when used together. Don't mix willy-nilly. Take a look at Peter Wilson's "A few notes on book design" (available as memdesign on CTAN). Typesetting is an art and a profession with it's rules, product of literally centuries of experience. Yes, you can break the rules, they aren't set in stone, our present tools allow any random user freedoms that couldn't be dreamed of by professionals with the best that was available a few decades back. But better understand their rationale before doing so.

Thank you, @vonbrand. The question has already been addressed. — Ujan, Feb 23 '20 at 03:57

A good sans-serif companion for Palatino is Optima (also available as the clone URW Classico). A math font that matches Palatino well is Euler. All three fonts are by the same designer.

Some ways you can get them:

If you can use LuaLaTeX or XeLaTeX, you can load unicode-math, set the Roman font to Palatino (TeX Gyre Pagella), the sans-serif font to Optima (URW Classico), Asana Math as the main math font, and the math letters from Neo Euler.
In PDFLaTeX, you can load the packages tgpagella, classico and eulerpx to set up your font families. You must run the getnonfreefonts script from CTAN to get classico.
If you want the sans-serif math font, you can use mathastext, sansmath or (in XeLaTeX) mathspec with newpxmath.
