MSSM A-funnel and the Galactic Center Excess: Prospects for the LHC and
  Direct Detection Experiments
  The pseudoscalar resonance or "A-funnel" in the Minimal Supersymmetric
Standard Model~(MSSM) is a widely studied framework for explaining dark matter
that can yield interesting indirect detection and collider signals. The
well-known Galactic Center excess (GCE) at GeV energies in the gamma ray
spectrum, consistent with annihilation of a $\lesssim 40$ GeV dark matter
particle, has more recently been shown to be compatible with significantly
heavier masses following reanalysis of the background. In this paper, we
explore the LHC and direct detection implications of interpreting the GCE in
this extended mass window within the MSSM A-funnel framework. We find that
compatibility with relic density, signal strength, collider constraints, and
Higgs data can be simultaneously achieved with appropriate parameter choices.
The compatible regions give very sharp predictions of 200-600 GeV CP-odd/even
Higgs bosons at low tan$\beta$ at the LHC and spin-independent cross sections
$\approx 10^{-11}$ pb at direct detection experiments. Regardless of
consistency with the GCE, this study serves as a useful template of the strong
correlations between indirect, direct, and LHC signatures of the MSSM A-funnel
region.
