[Tex/LaTex] textsl in Beamer

beameritalicslanted

I notice that the \textit and \textsl behave much alike in Beamer. The following MWE produces the image:

\documentclass{beamer}

\begin{document}
\begin{frame}{}
\textsl{Welcome to my world!}

\textit{Welcome to my world!}
\end{frame}
\end{document}

.

How can these two can be made different, as they are in Article class:

\documentclass{article}

\begin{document}
\textsl{Welcome to my world!}

\textit{Welcome to my world!}
\end{document}

If choosing another fonttheme you will see, that beamer makes a difference between textsl and textit.

\documentclass{beamer}

\usefonttheme{serif}

\begin{document}
    \begin{frame}{}
        \textsl{Welcome to my world!}

        \textit{Welcome to my world!}
    \end{frame}
\end{document}
