What solution do you think is more elegant for a simple fraction that should be displayed in just one line?
My examples are
$x_F \equiv \frac{p_z}{p^{\rm MAX}_{z}} = \frac{p_z}{\sqrt{s}/2}$
$x_F \equiv \frac{p_z}{p^{\rm MAX}_{z}} = \frac{p_z}{\sfrac{\sqrt{s}}{2}}$
$x_F \equiv \frac{p_z}{p^{\rm MAX}_{z}} = \frac{p_z}{^\sqrt{s}/_2}$
This generates the following (using the xfrac
package).
I don't like 2, but I also think that 3 is not very elegant.
\sfrac
defined? Do you enable this command by loading a package?
