Root sqrt style in latex


Attached two pictures shows how the styles of the #sqrt symbol are different in ROOT and in Latex. Is there an easy way to produce the same ROOT #sqrt symbol in Latex ? any help is appreciated. thanks.

Using the default TLatex the square root is drawn as lines. That’s why you get this not-so-good result.

If you need Latex look you can use TMathText:
see how to use it here:
be aware that the PDF output is not implemented and that PS are big.

You can also use:

unfortunately, this is still not clear to me. attached picture is produced with ROOT and I should keep this sqrt style. I don’t want to change it because it is our TDR style.

In my latex document, what I get in math mode is different than ROOT style. I would like to use ROOT sqrt symbol in my latex document. The question is how can I produce ROOT sqrt symbol (attached picture) in Latex math mode ?

So you would like LaTex to produce a square ROOT like same way as ROOT ?..
weird …
Anyway that’s not possible.

As I said the square root produced by TLatex is drawn with lines … and LaTeX uses a symbol … usually people want the opposite as what you ask here …

Can I find the source code to see how the lines are drawn ? In this way, maybe I can do draw it using TikZ package in Latex.

Seems to me you should not do that …

But if you insist, it is in TLatex … PaintLatex … good luck …
