Query: The strange case of HESS J0632+057 and the \gamma-ray High Mass X-ray
  Binaries   In the last decade Cherenkov telescopes on the ground and space-based
\gamma-ray instruments have identified a new class of high mass X-ray binaries
(HMXB), whose emission is dominated by \gamma rays. To date only five of these
systems are known. All of them are detected by Cherenkov telescopes in the TeV
energy range, while at GeV energies there is still one (HESS J0632+057) that
has no reported detection with the Fermi-LAT. A deep search for \gamma-ray
emission of HESS J0632+057 has been performed using more than 3.5 years of
Fermi-LAT data. We discuss the results of this search and compare it to other
\gamma-ray binary systems.
