Nuclear modification of $\Upsilon$ states in pPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV / CMS Collaboration
Production cross sections of $\Upsilon$(1S), $\Upsilon$(2S), and $\Upsilon$(3S) states decaying into ${\mu^{+}\mu^{-}}$ in proton-lead (pPb) collisions are reported using data collected by the CMS experiment at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV. A comparison is made with corresponding cross sections obtained with pp data measured at the same collision energy and scaled by the Pb nucleus mass number. [...]

First measurement of large area jet transverse momentum spectra in heavy-ion collisions / CMS Collaboration
Jet production in lead-lead (PbPb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is studied with the CMS detector at the LHC, using PbPb and pp data samples corresponding to integrated luminosities of 404 $\mu$b$^{-1}$ and 27.4 pb$^{-1}$, respectively. Jets with different areas are reconstructed using the anti-$k_{\mathrm{T}}$ algorithm by varying the distance parameter $R$. [...]

Evidence for X(3872) in Pb-Pb Collisions and Studies of its Prompt Production at $\sqrt {s_{NN}}$=5.02  TeV / CMS Collaboration
The first evidence for X(3872) production in relativistic heavy ion collisions is reported. The X(3872) production is studied in lead-lead (PpPb) collisions at a center-of-mass energy of ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV per nucleon pair, using the decay chain ${\mathrm{X}(3872)} \to \mathrm{J}/\psi\,\pi^{+}\pi^{-}\to \mu^{+}\mu^{-}\pi^{+}\pi^{-}$.

Studies of charm and beauty hadron long-range correlations in pp and pPb collisions at LHC energies / CMS Collaboration
Measurements of the second Fourier harmonic coefficient ($v_2$) of the azimuthal distributions of prompt and nonprompt ${\mathrm{D^0}}$ mesons (the latter coming from beauty hadron decays) produced in pp and pPb collisions are presented. The data samples are collected by the CMS experiment at nucleon-nucleon center-of-mass energies of 13 and 8.16 TeV, respectively. [...]

Investigation into the event-activity dependence of $\Upsilon(\text{nS})$ relative production in proton-proton collisions at $\sqrt{s} = $ 7 TeV / CMS Collaboration
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. The data are from proton-proton collisions at $\sqrt{s} = $ 7 TeV, corresponding to an integrated luminosity of 4.8 fb$^{-1}$, collected with the CMS detector at the LHC. [...]

Performance of the CMS Level-1 trigger in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
At the start of Run 2 in 2015, the LHC delivered proton-proton collisions at a center-of-mass energy of 13 TeV. During Run 2 (years 2015-2018) the LHC eventually reached a luminosity of 2.1 $\times $ 10$^{34} $ cm$^{-2}$s$^{-1}$, almost three times that reached during Run 1 (2009-2013) and a factor of two larger than the LHC design value, leading to events with up to a mean of about 50 simultaneous inelastic proton-proton collisions per bunch crossing (pileup).

Dependence of inclusive jet production on the anti-${k_{\mathrm{T}}}$ distance parameter in pp collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
The dependence of inclusive jet production in proton-proton collisions with a center-of-mass energy of 13 TeV on the distance parameter $R$ of the anti-${k_{\mathrm{T}}}$ algorithm is studied using data corresponding to integrated luminosities up to 35.9 fb$^{-1}$ collected by the CMS experiment in 2016. The ratios of the inclusive cross sections as functions of transverse momentum ${p_{\mathrm{T}}}$ and rapidity $y$, for $R$ in the range 0.1 to 1.2 to those using $R= $ 0.4 are presented in the region 84 $ < {p_{\mathrm{T}}} < $ 1588 GeV and $|y| < $ 2.0.
