High resolution spectroscopic analysis of seven giants in the bulge
  globular cluster NGC 6723
  Globular clusters associated with the Galactic bulge are important tracers of
stellar populations in the inner Galaxy. High resolution analysis of stars in
these clusters allows us to characterize them in terms of kinematics,
metallicity, and individual abundances, and to compare these fingerprints with
those characterizing field populations. We present iron and element ratios for
seven red giant stars in the globular cluster NGC~6723, based on high
resolution spectroscopy. High resolution spectra ($R\sim48~000$) of seven K
giants belonging to NGC 6723 were obtained with the FEROS spectrograph at the
MPG/ESO 2.2m telescope. Photospheric parameters were derived from $\sim130$ FeI
and FeII transitions. Abundance ratios were obtained from line-to-line spectrum
synthesis calculations on clean selected features. An intermediate metallicity
of [Fe/H]$=-0.98\pm0.08$ dex and a heliocentric radial velocity of
$v_{hel}=-96.6\pm1.3~km s^{-1}$ were found for NGC 6723. Alpha-element
abundances present enhancements of $[O/Fe]=0.29\pm0.18$ dex,
$[Mg/Fe]=0.23\pm0.10$ dex, $[Si/Fe]=0.36\pm0.05$ dex, and $[Ca/Fe]=0.30\pm0.07$
dex. Similar overabundance is found for the iron-peak Ti with
$[Ti/Fe]=0.24\pm0.09$ dex. Odd-Z elements Na and Al present abundances of
$[Na/Fe]=0.00\pm0.21$ dex and $[Al/Fe]=0.31\pm0.21$ dex, respectively. Finally,
the s-element Ba is also enhanced by $[Ba/Fe]=0.22\pm0.21$ dex. The enhancement
levels of NGC 6723 are comparable to those of other metal-intermediate bulge
globular clusters. In turn, these enhancement levels are compatible with the
abundance profiles displayed by bulge field stars at that metallicity. This
hints at a possible similar chemical evolution with globular clusters and the
metal-poor of the bulge going through an early prompt chemical enrichment.
