Observation of the electroweak production of W$\gamma$ in association with two jets in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
A measurement of the electroweak (EW) production of a W boson and a photon in association with two jets in proton-proton collisions, where the W boson decays leptonically, is presented. Events are selected by requiring one identified electron or muon, missing transverse momentum, one photon, and two jets with a large dijet mass and a large rapidity separation. [...]

The ${\rm B_c^+(2S)}$ to ${\rm B_c^+}$ and ${\rm B_c^{*+}(2S)}$ to ${\rm B_c^+}$ cross section ratios, as well as the ${\rm B_c^{*+}(2S)}$ to ${\rm B_c^+(2S)}$ cross section ratio, are measured in proton-proton collisions at $\sqrt{s} = 13$ TeV, using a data sample collected by the CMS experiment, corresponding to an integrated luminosity of 143 fb$^{-1}$. The three measurements are made in the ${\rm B_c^+}$ phase space window defined by transverse momentum $p_{\rm T} > 15$ GeV and absolute rapidity $|y| < 2.4$, with the excited ${\rm B_c^{(*)+}(2S)}$ states reconstructed in their ${\rm B_c^+} \pi^+ \pi^-$ decay.

MUSiC, a model unspecific search for new physics, in pp collisions at sqrt(s)=13 TeV /CMS Collaboration
Results of the Model Unspecific Search in CMS (MUSiC) using data recorded by the CMS detector at the LHC, during proton-proton collisions at a center of mass energy of $\sqrt{s}=13~\mathrm{TeV}$ in 2016 and corresponding to an integrated luminosity of $35.9~\mathrm{fb^{-1}}$, are presented. The MUSiC analysis aims to search for anomalies that could be probed as signatures for phenomena beyond the standard model, and is based on the comparison of data with the expectation according to the standard model, determined from simulations, in several hundred final states and multiple kinematic distributions.
