Abstract
Results are presented for an extraction of the top quark Yukawa coupling from top quark-antiquark (
t
¯
t
) kinematic distributions in the lepton plus jets final state in proton-proton collisions, based on data collected by the CMS experiment at the LHC at
√
s
=
13
TeV
, corresponding to an integrated luminosity of

fb

. Corrections from weak boson exchange, including Higgs bosons, between the top quarks can produce large distortions of differential distributions near the energy threshold of
t
¯
t
production. Therefore, precise measurements of these distributions are sensitive to the Yukawa coupling. Top quark events are reconstructed with at least three jets in the final state, and a novel technique is introduced to reconstruct the
t
¯
t
system for events with one missing jet. This technique enhances the experimental sensitivity in the low invariant mass region,
M

, and the number of reconstructed jets are compared with distributions representing different Yukawa couplings. These comparisons are used to measure the ratio of the top quark Yukawa coupling to its standard model predicted value to be

with an upper limit of 1.67 at the 95% confidence level.
