Selected Heavy Flavor distributions from CMS with first 13 TeV data
We report plots on heavy flavors from the early data collected by CMS at LHC at 13 TeV. We show dimuon invariant mass spectra for triggers deployed for heavy flavors analyses, performances on Quarkonia, B and D mesons. [...]

First Results from Dijet Resonance Search using 37 pb$^{-1}$ of proton-proton collisions at $\sqrt{s}$=13 TeV /CMS Collaboration
We present the first results of a search for new particles decaying to jet pairs using the dijet mass spectrum measured by the CMS detector in pp collisions at $\sqrt{s}$=13 TeV. The data used correspond to an integrated luminosity of 37 pb$^{-1}$. [...]

First look at top-quark selections with 13 TeV data /CMS Collaboration
This Performance Note presents some illustrative event displays and distributions of observables designed to study top-quark pairs, in the electron plus muon and in the single-lepton plus jets final states, and an event that passes a selection designed for single top produced by the t-channel electroweak mechanism with a single-muon final state. The data set consists of the first proton-proton collision data recorded by the CMS detector at a center-of-mass energy of 13 TeV with a magnetic field of 3.8 Tesla in the solenoid, during the LHC development run with a bunch spacing of 50 ns that took place in July 2015.
