Exploring the origin of D0 meson elliptic flow in PbPb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV using event shape engineering /CMS Collaboration
The effect of the initial collision geometry on the elliptic flow ($v_2$) in events with prompt $\mathrm{D^0}$ mesons produced in $\text{PbPb}$ collisions at $\sqrt{\smash[b]{s_{_{\mathrm{NN}}}}}=5.02\,\text{TeV}$ is studied using data from the CMS experiment. Using an event-shape engineering technique, initial-state eccentricities within a given centrality range are systematically varied. [...]

Search for a Higgs boson produced in association with a charm quark, decaying to two W bosons in the e$\nu\mu\nu$ final state /CMS Collaboration
This note presents a search for a Higgs boson produced in association with a charm quark (cH) which allows to probe the Higgs-charm Yukawa coupling $\kappa_{\text{c}}$. Higgs boson decays into a pair of W bosons are considered, where one W boson decays to an electron and a neutrino, while the other W boson decays to a muon and a neutrino. [...]

DeepMET: Improving missing transverse momentum estimation with a deep neural network /CMS Collaboration
At hadron colliders, the net transverse momentum of particles that do not interact with the detector (missing transverse momentum) is a crucial observable in many analyses. In the standard model, missing transverse momentum originates from neutrinos. [...]
