Abstract	A search for direct pair production of bottom squarks, each decaying into a bottom quark and a neutralino, is performed in events with large missing transverse momentum and 2 bjets in the final state using 12.8 fb-1 of pp collisions at sqrt(s)=8 TeV recorded by the ATLAS detector at the LHC. For the particular scenario considered, sbottom masses up to 620 GeV are excluded for neutralino masses below 150 GeV. Differences in mass above 40 GeV between the b1 and the chi1 are excluded up to sbottom masses of 300 GeV. Neutralino masses are also excluded up to 320 GeV for sbottom masses around 550 GeV.
