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..

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..

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. [...]
