DESCRIPTION:Speakers: Gabrijela Zaharijas (University of Nova Gorica)\nHig
 h-energy gamma rays are among the most promising tools to constrain or rev
 eal the nature of dark matter (DM)\, in particular the Weakly Interacting 
 Massive Particles models.  The Cherenkov Telescope Array (CTA) is well int
 o its pre-construction phase and will soon probe the high-energy gamma-ray
  sky in the 20 GeV - 300 TeV energy range.  Thanks to its improved energy 
 and angular resolutions as well as significantly larger effective area\, t
 he CTA will probe a parameter space of heavier dark matter (above 100 GeV)
 \, with unprecedented sensitivity\, reaching the DM thermal annihilation r
 ate at the TeV regime. \n\nThis talk will summarise the planned DM search 
 strategies with CTA\, focusing on the signal of DM in the centre of our Ga
 laxy. As observed with the Fermi LAT at lower energies\, this region exhib
 its complex large-scale gamma-ray emission and the CTA is expected to be t
 he first ground based observatory able to detect it. In this talk we repor
 t on the collaboration effort to study the impact of extended astrophysica
 l backgrounds on DM search\, based on the astrophysical emission observed 
 with the Fermi LAT at lower energies and to suggest the promising data ana
 lysis and observational strategies for the upcoming CTA data.\n\nhttps://i
