Description
The first measurement of the jet mass m_{ {jet}} of top quark jets
produced in {t}\overline{t} events from pp collisions at √{s}=8
{TeV} is reported for the jet with the largest transverse momentum
pT in highly boosted hadronic top quark decays. The data
sample, collected with the CMS detector, corresponds to an integrated
luminosity of 19.7 {fb}^{-1}. The measurement is performed in the
lepton+jets channel in which the products of the semileptonic decay {t}
→ b W with W→ ℓ ν where ℓ is an electron or muon,
are used to select {t}\overline{t} events with large Lorentz boosts. The
products of the fully hadronic decay {t} → b W with W→ q
\overline{q} ' are reconstructed using a single Cambridge-Aachen jet
with distance parameter R=1.2, and pT >400 {GeV}. The
{t}\overline{t} cross section as a function of m_{ {jet}} 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_{ {jet}} distribution
is sensitive to the top quark mass m_{{t}}, and the data are used to
extract a value of m_{{t}} to assess this sensitivity.
