 Exclusive production observed at the CMS experiment / Chudasama, Ruchi (Bhabha Atomic Res. Ctr.) /CMS Collaboration Exclusive W+ W- pair production in photon-photon collisions during the pp runs at 7 and 8TeV are observed and used to put constraints on the Anomalous Quartic Gauge Couplings. During the proton lead collisions in photon-induced vector meson production is observed via the decay of Ypsilon into two muons. [...] CMS-CR-2016-149.- Geneva : CERN, 2016 - 9 p.

 Top quark mass measurements with the CMS experiment at the LHC / Spannagel, Simon (DESY) /CMS Collaboration Measurements of the top quark mass are presented, obtained from CMS data collected in proton proton collisions at the LHC at centre-of-mass energies of 7 TeV and 8 TeV. The mass of the top quark is measured using several methods and channels, including the reconstructed invariant mass distribution of the top quark as well as measurements based on charged particle information.

 Exclusive pi+ pi- production at 7TeV / Khakzad, Mohsen (IPM, Tehran) /CMS Collaboration We report a measurement of the exclusive production of pairs of charged pions in proton-proton collisions, dominated by the process $pp \rightarrow p^{(*)} \pi^{+}\pi^{-} p^{(*)}$, where $\rm p^{(*)}$ stands for a diffractively dissociated proton, the $\pi^{+} \pi^{-}$ pair is emitted at central rapidities $y$, and the incident protons stay intact or dissociate without detection ${\rm p^{(*)}}$. The measurement is performed with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 450~$\mu$b$^{-1}$ collected at a center-of-mass energy of $\sqrt{s}$ = 7 TeV in 2010 [...] CMS-CR-2016-144.- Geneva : CERN, 2016 - 7 p.

 Searches for BSM physics in dilepton, multilepton, and lepton+MET final states at CMS / Thomas, Laurent (Florida U.) /CMS Collaboration We describe various searches for signs of physics beyond the Standard Model in proton-proton collisions collected by CMS in 2012 or 2015. These datasets correspond respectively to around 20 fb$^{-1}$ of integrated luminosity at a center of mass energy ($\sqrt{s}$) of 8 TeV and around 2.5 fb$^{-1}$ at $\sqrt{s}=$ 13 TeV. The analyses presented here focus on final states with one or several leptons and possibly missing transverse energy, for which the background from Standard Model processes is reduced, and primarily targets the production of new particles with masses in the TeV range.

 Searches for BSM physics in diphoton final state at CMS / Quittnat, Milena Eleonore (Zurich, ETH) /CMS Collaboration Many physics scenarios beyond the standard model predict the existence of heavy resonances decaying to diphotons. This note presents searches for BSM physics in the diphoton final state at CMS, focusing on the recent results obtained using data collected at the LHC in 2015..

 Measurement of the inelastic proton-proton cross section at 13TeV / Van Haevermaet, Hans (Antwerp U.) /CMS Collaboration A measurement of the inelastic proton-proton cross section at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV is presented. The analysis is performed using the CMS detector, in particular with information from forward calorimetry at pseudorapidities of 3.0 lt Î· lt 5.2 and -6.6 lt Î· lt -3.0.

 Heavy flavour production at CMS / Negro, Giulia (IRFU, Saclay) /CMS Collaboration Three recent results in heavy flavour production at the CMS experiment are addressed in this report.

 B hadron properties at CMS / Heredia De La Cruz, Ivan (CINVESTAV, IPN) /CMS Collaboration Precise measurements of B hadron properties are crucial to improve or constrain models based on non-perturbative quantum chromodynamics, which provide predictions of mass, lifetime, cross section, polarization, and branching ratios (among several other properties) of B hadrons. Measurements of CP violation in $B^0_s$ and properties of rare B decays also provide many opportunities to search for new physics. [...] CMS-CR-2016-131.- Geneva : CERN, 2016 - 8 p.

 Forward energy density per pseudorapidity and limiting fragmentation studied with CMS at 13TeV / Katkov, Igor (KIT, Karlsruhe, EKP) /CMS Collaboration The measurement of the energy flow in the forward angular range performed by CMS at LHC is a means of studying soft particle production and testing hadronic interaction models used in collider as well as cosmic ray physics. The two important ingredients necessary for the measurement, forward instrumentation of CMS and the accelerator providing collisions with low pile-up, performed very well in 201 at the start up of the operation at 13 TeV..

 Distributions of charged particles at 13 TeV with CMS / Grados Luyando, Juan Manuel (DESY) /CMS Collaboration Pseudorapidity distributions of charged-particles, $\textrm{d}N_{\textrm{\tiny{ch}}}/\textrm{d}\eta$, produced in proton-proton collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV are measured in the pseudorapidity range $\left\lvert\eta\right\rvert < 2.4$ for charged-particles with a transverse momentum $p_T~>~0.5$~GeV. Measurements are presented for four event categories. [...] CMS-CR-2016-113.- Geneva : CERN, 2016 - 9 p.
