 Measurement of $b$-hadron fractions in 13 TeV $pp$ collisions The production fractions of $\overline{B}{_s^0}$ and $\Lambda_b^0$ hadrons, normalized to the sum of $B^-$ and $\overline{B}{^0}$ fractions, are measured in 13 TeV pp collisions using data collected by the LHCb experiment, corresponding to an integrated luminosity of 1.67fb$^{-1}$.

 Combinations of single-top-quark production cross-section measurements and $|f_{\rm LV}V_{tb}|$ determinations at $\sqrt{s}=7$ and 8 TeV with the ATLAS and CMS experiments This paper presents the combinations of single-top-quark production cross-section measurements by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at $\sqrt{s}=7$ and 8 TeV corresponding to integrated luminosities of 1.17 to 5.1 fb$^{-1}$ at $\sqrt{s}=7$ TeV, and 12.2 to 20.3 fb$^{-1}$ at $\sqrt{s}=8$ TeV.

 Measurements of bottomonium production in pp and PbPb collisions at $\sqrt{s_{\mathrm{NN}}\space}$ = 5.02 TeV / Oh, Geonhee (Chonnam Natl. U.) /CMS Collaboration Bottomonia are important probes of the quark-gluon plasma since they are produced at early times and propagate through the medium. The production cross sections of the three $\Upsilon$ states (1S, 2S, 3S) were measured by CMS in pp and PbPb collisions at $\sqrt{s_{\mathrm{NN}}\space}$ = 5.02 ${\mathrm{TeV}}\space$.

 Vector Boson Production in Association with a Jet at Forward Rapidities / Gehrmann-De Ridder, A. (Zurich, ETH ; Zurich U.) ; Gehrmann, T. (Zurich U.) ; Glover, E.W.N. (Durham U., IPPP) ; Huss, A. (CERN) ; Walker, D.M. (Durham U., IPPP) Final states with a vector boson and a hadronic jet allow one to infer the Born-level kinematics of the underlying hard scattering process, thereby probing the partonic structure of the colliding protons.
