Measurement of the jet mass in highly boosted t[bar over t] events from pp collisions at √s=8 TeV
The first measurement of the jet mass m[subscript jet] of top quark jets produced in t[bar over t] events from pp collisions at √s=8 TeV is reported for the jet with the largest transverse momentum p[subscript T] in highly boosted hadronic top quark decays. The data sample, collected with the CMS de...

| description | The first measurement of the jet mass m[subscript jet] of top quark jets produced in t[bar over t] events from pp collisions at √s=8 TeV is reported for the jet with the largest transverse momentum p[subscript T] in highly boosted hadronic top quark decays. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 19.7 fb[superscript -1]. The measurement is performed in the lepton+jets channel in which the products of the semileptonic decay t→bW with W→ℓν where ℓ is an electron or muon, are used to select t[bar over t] events with large Lorentz boosts. The products of the fully hadronic decay t→bW with W→q[bar over q]′ are reconstructed using a single Cambridge–Aachen jet with distance parameter R=1.2 , and p[subscript T]>400 GeV . The t[bar over t] cross section as a function of mjet is unfolded at the particle level and is used to test the modelling of highly boosted top quark production. The peak position of the m[subscript jet] distribution is sensitive to the top quark mass m[subscript t], and the data are used to extract a value of mt to assess this sensitivity.
