First, note that Mathematica handles AMS-LaTeX. Depending on how the 
code you have adheres to this standard, you will get varying results 
with the automatic conversion process.

Converting a LaTeX file can be done via the command *Import* [1], e.g.

     Import["filename.tex"]

If you want to convert just one expression in TeX/LaTeX, you can use use 
ToExpression with the option TeXForm [2, 3].

Note that the expression must be enclosed within double quotes, must 
start and end with a dollar sign, and backlashes must be repeated.

In[12]:= ToExpression["$ln{H}^{*}&={X}_{1}
{\\beta}_{1}+{\\alpha}_{1}lnE+{\\varepsilon}_{1}\\\\$", TeXForm]

Out[12]= l n
\!\(\*SuperscriptBox["H", "*"]\) ==
  E l n Subscript[\[Alpha], 1] +
   Subscript[X, 1] Subscript[\[Beta], 1] + Subscript[\[Epsilon], 1]
