abstract = {A search for γH production is performed with data from the
CMS experiment at the LHC corresponding to an integrated
luminosity of 138 fb-1 at a proton-proton center-of-mass
collision energy of 13 TeV. The analysis focuses on the
topology of a boosted Higgs boson recoiling against a
high-energy photon. The final states of H→bb¯ and
H→4ℓ are analyzed. This study examines effective HZγ
and Hγγ anomalous couplings within the context of an
effective field theory. In this approach, the production
cross section is constrained to be σγH<16.4 fb at $95\%$
confidence level (CL). Simultaneous constraints on four
anomalous couplings involving HZγ and Hγγ are provided.
Additionally, the production rate for H→4ℓ is examined
to assess potential enhancements in the Yukawa couplings
between light quarks and the Higgs boson. Assuming the
standard model values for the Yukawa couplings of the bottom
and top quarks, the following simultaneous constraints are
obtained: κu=(0.0±1.5)×103, κd=(0.0-6.8+6.7)×102,
κs=0-32+30, and κc=0.0-2.8+2.3. This rules out the
hypothesis that up- or down-type quarks in the first or
second generation have the same Yukawa couplings as those in
the third generation, with a CL greater than $95\%.$},
