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. [...]

Measurement of the charge asymmetry of electrons from the decays of $W$ bosons produced in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV / CDF Collaboration
At the Fermilab Tevatron proton-antiproton ($p\bar{p}$) collider, high-mass electron-neutrino ($e\nu$) pairs are produced predominantly in the process $p \bar{p} \rightarrow W(\rightarrow e\nu) + X$. The asymmetry of the electron and positron yield as a function of their pseudorapidity constrain the slope of the ratio of the $u$- to $d$-quark parton distributions versus the fraction of the proton momentum carried by the quarks.

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.

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. [...]
