Investigation into the event-activity dependence of $\Upsilon(\text{nS})$ relative production in proton-proton collisions at $\sqrt{s} = $ 7 TeV
The ratios of the production cross sections between the excited $\Upsilon\text{(2S)}$ and $\Upsilon\text{(3S)}$ mesons and the $\Upsilon\text{(1S)}$ ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event. [...]

Measurement of the CP-violating phase ${\phi_{\mathrm{s}}}$ in the ${\mathrm{B^{0}_{s}}\to\mathrm{J}/\psi\,\phi(1020) \to \mu^{+}\mu^{-}\,{\mathrm{K^{+}}\mathrm{K^{-}}} } $ channel in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
The CP-violating weak phase ${\phi_{\mathrm{s}}}$ and the decay width difference $\Delta\Gamma_{\mathrm{s}}$ between the light and heavy $\mathrm{B^{0}_{s}}$ mass eigenstates are measured with the CMS detector at the LHC in a sample of 48 500 reconstructed ${\mathrm{B^{0}_{s}}\to\mathrm{J}/\psi\,\phi(1020) \to \mu^{+}\mu^{-}\,{\mathrm{K^{+}}\mathrm{K^{-}}} }$ events.

Measurement of the inclusive and differential Higgs boson production cross sections in the leptonic WW decay mode at $\sqrt{s} = $ 13 TeV / CMS Collaboration
Measurement of the fiducial inclusive and differential production cross sections of the Higgs boson in proton-proton collisions at $\sqrt{s} = $ 13 TeV are performed using events where the Higgs boson decays into a pair of W bosons that subsequently decay into a final state with an electron, a muon, and a pair of neutrinos.

Inclusive search for highly boosted Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
A search for standard model Higgs bosons (H) produced with transverse momentum (${p_{\mathrm{T}}}$) greater than 450 GeV and decaying to bottom quark-antiquark pairs ($\mathrm{b\bar{b}}$) is performed using proton-proton collision data collected by the CMS experiment at the LHC at $\sqrt{s} = $ 13 TeV.

Evidence for top quark production in nucleus-nucleus collisions / CMS Collaboration
Ultrarelativistic heavy ion collisions recreate in the laboratory the thermodynamical conditions prevailing in the early universe up to 10$^{-6}$ seconds, thereby allowing the study of the quark-gluon plasma (QGP), a state of quantum chromodynamics (QCD) matter with deconfined partons. [...]
