Exploring the origin of D0 meson elliptic flow in PbPb collisions at √sNN = 5.02 TeV using event shape engineering /CMS Collaboration
The effect of the initial collision geometry on the elliptic flow (v2) in events with prompt D0 mesons produced in PbPb collisions at √sNN=5.02TeV 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 eνμν 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 κc. 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. [...]
