Determination and application of TMD parton densities using the Parton Branching method

We present a determination of parton densities at NLO obtained with the Parton Branchingmethod using precision measurements of deep inelastic scattering cross sections at HERA. Thetwo sets of parton densities shown in this work are obtained with the same angular angular orderingcondition for the evolution scale and they differ in the chosen scale for the $\alpha_s$ evaluation, forwhich we consider two scenarios: the evolution scale, and the transverse momentum $q_T$ from theangular ordering prescription [...]

Recent results on the Higgs boson decays into $WW^*$, $ZZ^*$ and $\gamma\gamma$, obtained with the 2016 datacollected by the CMS experiment, are presented. The decays into a pair ofWbosons was observedwith a significance of 9.1 $\sigma$ and has achieved a comparable precision in signal strength comparedto the other two channels. [...]

Search for a charged Higgs boson decaying to charm and bottom quarks in proton-proton collisions at $\sqrt{s} =$ 8 TeV
[arXiv:1808.06575; CMS-HIG-16-030; CERN-EP-2018-121]
 GO
A search for charged Higgs boson decaying to a charm and a bottom quark (H$^+\to$ c$\overline{\mathrm{b}}$) is performed using 19.7 fb$^{-1}$ of pp collision data at $\sqrt{s} =$ 8 TeV. The production mechanism investigated in this search is $\mathrm{t\overline{t}}$ pair production in which one top quark decays to a charged Higgs boson and a bottom quark and the other decays to a charged lepton, a neutrino, and a bottom quark.

Measurement of jet substructure observables in $\mathrm{t\overline{t}}$ events from proton-proton collisions at $\sqrt{s}=$ 13TeV
[arXiv:1808.07340; CMS-TOP-17-013; CERN-EP-2018-214]
 GO
A measurement of jet substructure observables is presented using \ttbar events in the lepton+jets channel from proton-proton collisions at $\sqrt{s}=$ 13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Multiple jet substructure observables are measured for jets identified as bottom, light-quark, and gluon jets, as well as for inclusive jets (no flavor information). [...]

Observation of Higgs boson decay to bottom quarks
[arXiv:1808.08242; CMS-HIG-18-016; CERN-EP-2018-223]
The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for in final states including 0, 1, or 2 charged leptons and two identified bottom quark jets.
