In the $pp \\rightarrow t\\bar{t}$ process the angular distributions of top and anti-top quarks are expected to present a subtle difference, which could be enhanced by processes not included in the Standard Model. This Letter presents a measurement of the charge asymmetry in events where the top-quark pair is produced with a large invariant mass. The analysis is performed on 20.3 fb$^{-1}$ of $pp$ collision data at $\\sqrt{s} =$ 8 TeV collected by the ATLAS experiment at the LHC, using reconstruction techniques specifically designed for the decay topology of highly boosted top quarks. The charge asymmetry in a fiducial region with large invariant mass of the top-quark pair ($m_{t\\bar{t}} > $ 0.75 TeV) and an absolute rapidity difference of the top and anti-top quark candidates within $-$2 $ < |y_t| - |y_{\\bar{t}}| <$ 2 is measured to be 4.2 $\\pm$ 3.2%, in agreement with the Standard Model prediction at next-to-leading order. A differential measurement in three $t\\bar{t}$ mass bins is also presented.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.77021.v1/t1","@type":"Dataset","description":"The measured charge asymmetry after the unfolding to parton level in four intervals of the invariant mass of the $t\\bar{t}$...","name":"Table 1"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1410588?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/77021"}],"inLanguage":"en","name":"Measurement of the charge asymmetry in highly boosted top-quark pair production in $\\sqrt{s} =$ 8 TeV $pp$ collision data collected by the ATLAS experiment","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1410588?version=1","version":1}
