Electroweak and QCD aspects in vector boson plus jets associated production with CMS / Kirschenmann, Henning (Helsinki U.) /CMS Collaboration
The study of the associated production of vector bosons and jets constitutes an excellent testbench to check numerous QCD predictions. Measurements of the total and differential cross sections of vector bosons produced in association with jets have been performed at 13 TeV center-of-mass energies with the CMS experiment at the LHC.

Search for Z$\gamma$ resonances using leptonic and hadronic final states in proton-proton collisions at 13 TeV with the CMS experiment / Nam, Kyungwook (Seoul Natl. U.) /CMS Collaboration
A search for Z$\gamma$ resonances using leptonic and hadronic final states is presented. The analysis is based on data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 /fb, and collected with the CMS detector at the LHC in 2016.

Searches for non-resonant new phenomena in final states with leptons and photons / Nam, Kyungwook (Seoul Natl. U.) /CMS Collaboration
Many new physics models, e.g., compositeness, see-saw, and extra dimensions models, are expected to manifest themselves in the final states with leptons and photons. This talk presents searches for new non-resonant phenomena in the final states that include leptons and photons, focusing on the recent results obtained using data collected at Run-II of the LHC..

Recent CMS results on inelastic cross section measurements / Sen, Sercan (Istanbul, Tech. U.) /CMS Collaboration
A measurement of the inelastic proton-proton (pp) cross section is presented. The analysis is based on the data collected in 2015 at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. [...]

Latest results of diffractive and exclusive measurements with CMS / Bylinkin, Alexandr (Kansas U.) /CMS Collaboration
Exclusive $\rho(770)^{0}$ photoproduction is studied for the first time in ultra-peripheral pPb collisions at $\sqrt{s_{\rm{NN}}} = 5.02~\mathrm{TeV}$. The cross section, $\sigma (\gamma \mathrm{p} \rightarrow \rho(770)^{0} \rm{p})$, is measured for photon-proton centre-of-mass energies, $W_{\gamma \rm{p}}$, between $29$ and $213~\mathrm{GeV}$ with the CMS experiment.

Search for Heavy Majorana Neutrinos in Events with Same-Sign Lepton Pairs and Jets Using the CMS Detector in pp Collisions at $\sqrt{s}=13~\mathrm{TeV}$ / Kim, Jae Sung (Seoul Natl. U.) /CMS Collaboration
We present searches on Heavy Majorana neutrinos in events with same-sign lepton pairs and jets, using the collision data collected with the CMS detector at a centre-of-mass energy 13 TeV. The search range is extended to 20 GeV and 1500 GeV, lower and upper bound respectively, compared to the previous analysis using 8 TeV data. The vector boson fusion production channel is considered as well as the s-channel, which improves the sensitivities for mass above by several hundreds of GeV. We set upper limits on muon mixing squared, electron mixing squared, and muon-electron cross mixing..

Multiboson production at CMS / Bellan, Riccardo (INFN, Turin ; Turin U.) /CMS Collaboration
Precision measurements of multiboson production are a validation of the Standard Model. These multiboson processes are a background to Higgs boson measurements and searches for Beyond the Standard Model physics. [...]

Fast timing measurement for the CMS RPC Phase II upgrade / Gouzevitch, Maxime (Lyon, IPN) /CMS Collaboration
With the increase of the LHC luminosity foreseen in the coming years many detectors currently used in the different LHC experiments will be dramatically impacted and some need to be replaced. The new ones should be capable not only to support the high particle rate but also to provide time information to reduce the data ambiguity due to the expected high pileup. The Resistive Plate Chambers (RPC) using low-resistivity Bakelite are proposed to equip the very forward region of the CMS detector. [...]

Forward physics / Da Silveira, Gustavo Gil (Rio de Janeiro State U.) /CMS Collaboration
Since the start of operation of the CERN-LHC, its experiments are achieving a new frontier in colliding energy, allowing detailed studies of the Standard Model. Part of the physics interests of the CMS Collaboration has been focusing on the forward region to investigate energy distributions and proton tagged events. [...]
