Observation of $\gamma\gamma\rightarrow\tau\tau$ in proton-proton collisions and limits on the anomalous electromagnetic moments of the $\tau$ lepton
/CMS Collaboration
The photon-induced production of a pair of $\tau$ leptons, $\gamma\gamma\rightarrow\tau\tau$, is observed for the first time in proton-proton collisions. The observation is based on a data set recorded with the CMS detector at the LHC at a center-of-mass energy of $13~\mathrm{TeV}$ and corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$.

Luminosity measurement in proton-proton collisions at $13.6\,\mathrm{TeV}$ in 2022 at CMS
/CMS Collaboration
The measurement of the integrated luminosity for the proton-proton collisions data-taking period at a center-of-mass energy of $13.6\,\mathrm{TeV}$ in 2022 with the CMS experiment at the CERN LHC is reported. The absolute scale of the luminosity measurement is calibrated from beam-separation scans with the van der Meer scan method.

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. SUEPs are predicted by Hidden Valley models that include a new, confining force with a large 't Hooft coupling and are characterized by a large multiplicity of low-momentum, diffuse, charged particles in the final state.
