Production of $\Lambda_\mathrm{c}^+$ baryons in proton-proton and lead-lead collisions at $\sqrt{s_\mathrm{NN}}=$ 5.02 TeV
[arXiv:1906.03322; CMS-HIN-18-009; CERN-EP-2019-102]
 GO
The differential cross sections of $Λ^+_c$ baryon production are measured via the exclusive decay channel $Λ^+_c → pK^− π^+$, as a function of transverse momentum $(p_T)$ in proton-proton (pp) and lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV with the CMS detector at the LHC. The measurement is performed within the $Λ^+_c$ rapidity interval $|y| <$ 1.0 in the $p_T$ range of 5-20 GeV/c in pp and 10-20 GeV/c in PbPb collisions [...]

A multi-dimensional search for new heavy resonances decaying to boosted WW, WZ, or ZZ boson pairs in the dijet final state at 13 TeV
[arXiv:1906.05977; CMS-B2G-18-002; CERN-EP-2019-107]
 GO
A search in an all-jet final state for new massive resonances decaying to WW, WZ, or ZZ boson pairs using a novel analysis method is presented. The analysis is performed on data corresponding to an integrated luminosity of 77.3 fb$^{-1}$ recorded with the CMS experiment at the LHC at a centre-of-mass energy of 13 TeV. [...]

Production of Z-bosons in the parton branching method
[arXiv:1906.00919; DESY-19-087]
 GO
Transverse Momentum Dependent (TMD) parton distributions obtained from the Parton Branching (PB) method are combined with next-to-leading-order (NLO) calculations of Drell-Yan (DY) production. We apply the MCatNLO method for the hard process calculation and matching with the PB TMDs. [...]
