Studies of high-transverse momentum jet substructure and top quarks produced in $1.96 TeV$ proton-antiproton collisions


Aaltonen, T A; Amerio, S; Amidei, D E; et al; Canelli, F; Kilminster, B; CDF Collaboration (2015). Studies of high-transverse momentum jet substructure and top quarks produced in $1.96 TeV$ proton-antiproton collisions. Physical Review D (Particles, Fields, Gravitation and Cosmology), 91:032006.

Abstract

Results of a study of the substructure of the highest transverse momentum ($pT$) jets observed by the CDF Collaboration are presented. Events containing at least one jet with $pT > 400  GeV /c$ in a sample corresponding to an integrated luminosity of $5.95  fb^−1$, collected in 1.96 TeV proton-antiproton collisions at the Fermilab Tevatron collider, are selected. A study of the jet mass, angularity, and planar-flow distributions is presented, and the measurements are compared with predictions of perturbative quantum chromodynamics. A search for boosted top-quark production is also described, leading to a 95% confidence level upper limit of 38 fb on the production cross section of top quarks with $pT > 400  GeV/c$.
