Spin-dependent azimuthal asymmetry of coherent $\mathrm{J}/\psi$ photoproduction in peripheral PbPb collisions at $\sqrt{s_{_{NN}}}~=~5.36~\mathrm{TeV}$ /CMS Collaboration
We report on the measurement of azimuthal asymmetry in muons from the decay of coherently photoproduced $\mathrm{J}/\psi$ vector mesons in peripheral PbPb collisions. The analysis is based on data collected by the CMS experiment at the LHC at a nucleon-nucleon center-of-mass energy of $5.36~\mathrm{TeV}$, corresponding to an integrated luminosity of $1.26~\mathrm{nb}^{-1}$.

Search for H-aa-2mu2tau (boosted) /CMS Collaboration
A search for a light pseudoscalar Higgs boson ($\mathrm{a}$) is performed using LHC data collected at $\sqrt{s}=13~\mathrm{TeV}$ by the CMS experiment from 2016 to 2018, targeting the process $\mathrm{H} \to \mathrm{a}\mathrm{a} \to \mu\mu\tau\tau$, where the scalar $\mathrm{H}$ can be either the 125 GeV state or a heavier one. Due to the large mass difference between $\mathrm{H}$ and $\mathrm{a}$, the two tau leptons are highly boosted and collimated, often failing standard CMS tau lepton reconstruction. [...]

The $\Upsilon(\mathrm{nS})$ mesons are reconstructed via their decays to pairs of oppositely charged muons and are associated with anti-$k_{\mathrm{T}}$ jets if both muons are clustered among the jet constituents and the angular distance between the $\Upsilon(\mathrm{nS})$ candidate and the jet axis is smaller than the jet distance parameter, $R = 0.4$.
