 Initial-state fluctuations and factorization breaking in pPb and PbPb collisions at LHC energies / Milosevic, Jovan (VINCA Inst. Nucl. Sci., Belgrade) /CMS Collaboration The single-particle anisotropy coefficients measured in PbPb collisions at $\sqrt{s_{NN}}$=2.76~TeV and high-multiplicity pPb collisions at $\sqrt{s_{NN}}$=5.02~TeV by the CMS collaboration are presented. These coefficients are obtained from two-particle $\Delta\phi$-$\Delta\eta$ correlations. [...] CMS-CR-2014-444.- Geneva : CERN, 2014 - 10 p. Fulltext: PDF;

 Search for anomalous Wtb couplings and top FCNC in t-channel single-top-quark events in the CMS experiment / Tsirova, Natalia (Moscow State U.) /CMS Collaboration Single-top-quark events in the t-channel are used to probe Wtb anomalous couplings and to search for top-quark Flavor-Changing Neutral Current (FCNC) interactions in proton-proton collisions with the CMS experiment. A Bayesian neural network is used to discriminate between signal and backgrounds. [...] CMS-CR-2015-004.- Geneva : CERN, 2015 - 10 p. Fulltext: PDF;

 Plenary talk on CMS/ATLAS Higgs results / Sanabria Arenas, Juan Carlos (Andes U., Bogota) /ATLAS and CMS Collaborations The latest results from the ATLAS and CMS experiments on the Higgs boson properties, using 25 fb-1 of data from pp collisions at 7 and 8 TeV are presented. Both experiments perform studies in various channels with different final states. [...] CMS-CR-2015-008.- Geneva : CERN, 2015 - 11 p.

 Diffractive and Exclusive Processes at CMS / Kuznetsova, Ekaterina (St. Petersburg, INP) /CMS Collaboration We present an overview of the CMS results on diffractive and exclusive production.Measurements of inclusive single and double diffractive production are discussedas well as measurements of the diffractive production at a hard scale. Measurementsof charged particle multiplicities for single diffractive enhanced data sample and studies of central diffractive jet production were perfrmed in a collaboration with the TOTEM experiment.

 Bottomonia in pp, pPb and PbPb / Filipovic, Nicolas (Ecole Polytechnique) /CMS Collaboration Bottomonia are important probes of the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. The three $\Upsilon$ states (1S, 2S, 3S) were measured separately using the Compact Muon Solenoid (CMS) experimental apparatus and observed to disappear sequentially in PbPb collisions at 2.76 TeV.

 Search for a Higgs boson decaying into $\gamma \gamma^* \rightarrow \gamma \ell^+\ell^-$ in pp collisions at $\sqrt{s} = 8$ TeV at the CMS Experiment / Chaparro Sierra, Luisa Fernanda (Andes U., Bogota) /CMS Collaboration A search for a Higgs boson decaying into a real photon and a virtual photon ($\gamma\gamma^*$) where the virtual photon internally converts into leptons is performed. The rare Higgs boson decay into the $\ell\ell\gamma$ final state is rich of information, that will not only increase our understanding of its basic properties, but could also probe novel couplings caused by possible extensions of the standard model (SM) of particle physics.

 Beam Test Characterization of CMS Silicon Pixel Detectors for the Phase-1 Upgrade / Korol, Ievgen (DESY) /CMS Collaboration The Silicon Pixel Detector forms the innermost part of the CMS tracking system and is critical to track and vertex reconstruction. Being in close proximity to the beam interaction point, it is exposed to the highest radiation levels in the silicon tracker. [...] CMS-CR-2015-015.- Geneva : CERN, 2015 - 5 p.

 Multidimensional analysis of Bose-Einstein correlations in pp collisions at 2.76 and 7 TeV in CMS / Padula, Sandra (Sao Paulo, IFT) /CMS Collaboration Multidimensional two-particle Bose-Einstein correlation functions of charged hadrons are reported for pp collisions at 2.76 and 7 TeV in terms of different components of the pair relative momentum, extending the previous one-dimensional (1-D) analyses of CMS. This allows for investigating the extension of the source accessible to the femtoscopic correlation technique in different directions, revealing a more detailed picture of the emitting source in these collisions at increasing energies.

 Electroweak SUSY Searches at CMS using LHC-data collected at $\sqrt{s} = 8$ TeV / Florez Bustos, Carlos Andres (Andes U., Bogota) /CMS Collaboration The searches presented in this summary correspond to the electroweak (EWK) pair production of neutralinos ($\tilde{\chi}^{0}_{i}$) and charginos ($\tilde{\chi}^{\pm}_{1}$) decaying to Higgs (h), Z, and W bosons, and the lightest supersymmetric particle (LSP). The searches were performed using 19.5 $fb^{-1}$ of data from proton-proton collisions at the LHC, at a center of mass energy of 8 TeV collected in 2012 by the CMS detector.
