Search for soft unclustered energy patterns in proton-proton collisions at 13 TeV /CMS Collaboration
The first dedicated search for soft unclustered energy patterns (SUEPs) is performed in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$, using data collected by the CMS detector at the LHC.

Constraints on the Higgs boson self-coupling with combination of single and double Higgs boson production /CMS Collaboration
A combination of Higgs boson (H) measurements and searches for the production of Higgs boson pairs (HH) is presented, aiming to constrain the H trilinear self-coupling $\lambda_3$, using the proton-proton collision data collected by the CMS experiment at $\sqrt{s} = 13~\mathrm{TeV}$. The cross section of the main H production modes and the branching ratios of the principal decay channels depend on $\lambda_3$ because of next-to-leading-order electroweak corrections. [...]
