Abstract:
A search for supersymmetric partners of top quarks decaying as t˜1 → c χ˜0 and supersymmetric
partners of charm quarks decaying as c˜1 → c χ˜0, where
χ˜0 is the lightest neutralino, is
presented. The search uses 36.1 fb−1
pp collision data at a centre-of-mass energy of 13 TeV
collected by the ATLAS experiment at the Large Hadron Collider and is performed in final states
with jets identified as containing charm hadrons. Assuming a 100% branching ratio to 1 , top and
charm squarks with masses up to 850 GeV are excluded at 95% confidence level
for a massless lightest neutralino. For mt˜1,c˜1 − mχ˜0 < 100 GeV, top and charm squark masses
up to 500 GeV are excluded.
