 The Phase1 CMS Pixel detector upgrade / Tavolaro, Vittorio Raoul (Zurich, ETH) /CMS Collaboration The pixel detector of the CMS experiment will be replaced in an extended end-of-year shutdown during winter 2016/2017 with an upgraded one able to cope with peak instantaneous luminosities beyond the nominal LHC instantaneous luminosity of $1 \times 10^{34}$ cm$^{-2}$ s$^{-1}$. Under the conditions expected in the coming years, which will see an increase of a factor two in instantaneous luminosity, the present system would experience a dynamic inefficiency caused mainly by data losses due to buffer overflows.

 Diphoton searches (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 talk presents searches for BSM physics in the diphoton final state at CMS, focusing on the recent results.. CMS-CR-2016-251.- Geneva : CERN, 2016 - 13 p.

 Higgs boson parameters and decays into fermions / Bluj, Michal Jacek (NCBJ, Swierk) /ATLAS and CMS Collaborations In 2012 the discovery of a new boson with a mass of about 125 GeV and properties in agreement with those expected for the Higgs boson in the standard model was announced. In this note we review the results of searches for the fermionic decays the Higgs boson and the study of its properties performed with the proton-proton collision data recorded by the ATLAS and CMS detectors at the LHC in 2011 and 2012, corresponding to an integrated luminosity of approximately 5~fb$^{-1}$ and approximately 20~fb$^{-1}$ per experiment at $\sqrt{s}=7$~TeV and $\sqrt{s}=8$~TeV, respectively.

 Forward energy measurement with CMS / Kheyn, Lev (Moscow State U.) /CMS Collaboration Energy flow is measured in the forward region of CMS at pseudorapidities up to 6.6 in pp interactions at 13 TeV with forward (HF) and very forward (CASTOR) calorimeters. The results are compared to model predictions. [...] CMS-CR-2016-234.- Geneva : CERN, 2016 - 5 p.

 The CT-PPS tracking system with 3D pixel detectors / Ravera, Fabio (INFN, Turin ; Turin U.) /CMS Collaboration The CMS-TOTEM Precision Proton Spectrometer (CT-PPS) detector will be installed in Roman pots (RP) positioned on either side of CMS, at about 200 m from the interaction point. This detector will measure forward leading protons, allowing detailed studies of diffractive physics and central exclusive production in standard LHC running conditions.

 ttH production at 13 TeV (CMS) / Dordevic, Milos (VINCA Inst. Nucl. Sci., Belgrade) /CMS Collaboration First results of a search for the standard model Higgs boson produced in association with a top quark-antiquark pair (ttH) in proton-proton collisions at a center of mass energy of 13 TeV is presented. The decays of Higgs boson into two photons, bottom quark-antiquark pair and multileptons via WW, ZZ and tautau are analysed separately and then combined.

 CMS Heavy Flavor spectroscopy and exotica / Pompili, Alexis (INFN, Bari ; Bari U.) /CMS Collaboration In the last 13 years the discovered quarkonium-like states have renewed the interest in hadron spectroscopy and the LHC experiments are highly contributing to this field.Two relevant contributions by the CMS Collaboration to the exotic heavy flavour spectroscopy are discussed.The first study concerns the production of the $X(3872)$, either prompt or from beauty hadron decays. The cross-section ratio of the $X(3872)$ with respect to the $\psi(2S)$ in the $J/\psi \pi \pi$ decay channel and the fraction of $X(3872)$ coming from \textit{B}-hadron decays are measured as a function of transverse momentum ($p_{T}$), covering unprecedentedly high values of $p_{T}$.
