 CMS Pixel Detector: Operational Experience and Run1 to Run2 transition / De Cosa, Annapaola (Zurich U.) /CMS Collaboration The CMS Pixel detector is at the centre of the CMS experiment and is made of three barrel layers and four endcap disks. It is essential for the reconstruction of track seeds and secondary vertices. [...] CMS-CR-2014-418.- Geneva : CERN, 2014 - 12 p.

 Latest results on differential cross sections as a function of kinematic variables at the LHC and Tevatron / Diez, Carmen (DESY) /ATLAS, CDF, CMS and D0 Collaborations An overview of recent measurements of differential top quark pair ($t\bar{t}$) production cross sections is presented, including results in boosted topologies and results both at parton and particle level. The first measurements of differential single top quark t-channel production cross sections in proton-proton collisions are as well presented. [...] CMS-CR-2014-408.- Geneva : CERN, 2014 - 6 p.

 Higgs Boson decay to Tau Pairs \\at the CMS Experiment / Choudhury, Somnath (DESY) /CMS Collaboration The results on the standard model Higgs boson in tau pair decay using 25 fb$^{-1}$ of pp collision data at 7 and 8 TeV center-of-mass energies collected by the CMS detector at the LHC has been presented. A direct evidence of the Higgs-lepton coupling is established with the tau pair decay mode. [...] CMS-CR-2014-411.- Geneva : CERN, 2014 - 5 p.

 Search for H - gt bb in association with single top quarks as a test of Higgs couplings / Maier, Benedikt (Karlsruhe U., EKP) /CMS Collaboration A search for the production of the Higgs boson in association with a single top quark is performed using the decay H to bb. The rate for this Higgs production mode is particularly sensitive to the relative sign of the Higgs coupling to fermions and bosons. [...] CMS-CR-2014-412.- Geneva : CERN, 2014 - 5 p.

 Probing novel long-range correlation phenomena in pPb collisions with identified particles at CMS / Chen, Zhenyu (Rice U.) /CMS Collaboration Observation of a long-range near-side two-particle correlation (known as the Ridge) in high-multiplicity pp and pPb collisions opened up new opportunities of exploring novel QCD dynamics in small collision systems. To further investigate the origin of this phenomenon, studies of two-particle correlations with identified $K^0_s$ and Lambda trigger particles in 5.02 TeV pPb collisions are presented, and compared to PbPb collisions over a similar multiplicity range.

 The pixel detector for the CMS phase-II upgrade / Dinardo, Mauro (INFN, Milan Bicocca ; Milan Bicocca U.) /CMS Collaboration The high luminosity phase of the Large Hadron Collider (HL-LHC) requires a major pixel detector R\&D; effort to develop both readout chip and sensor that are capable to withstand unprecedented extremely high radiation. The target integrated luminosity of 3000~fb$^{-1}$, that the HL-LHC is expected to deliver over about 10 years of operation, translates into a hadron fluence of $2\times10^{16}$~1MeV~eq.n.~/~cm$^2$, or equivalently 10~MGy of radiation dose in silicon, at about 3~cm from the interaction region where the first layer of the pixel detector could be located.

 BSM Higgs / Lange, Clemens (Zurich U.) /ATLAS and CMS Collaborations Recent LHC highlights of searches for Higgs bosons beyond the Standard Model are presented. The results by the ATLAS and CMS collaborations are based on 2011 and 2012 proton-proton collision data at centre-of-mass energies of 7 and 8 TeV, respectively.

 Perspectives on top quark physics after Run I of the LHC: $\sqrt{s}=13$~TeV and beyond / Pedro Ferreira da Silva for the ATLAS (CERN) /ATLAS and CMS Collaborations A summary of the on-going preparations from the ATLAS and CMS collaborations to perform top quark physics in Run II of the LHC and at the HL-LHC is given. To maintain the current level of precision and profit from the high-luminosity scenario expected in the next runs of the LHC, several new reconstruction techniques and detector upgrades are foreseen. The prospects for precise measurements and possible discovery stories for new physics with top quarks are summarized.. CMS-CR-2014-353.- Geneva : CERN, 2014 - 7 p.

 Identification of signal events in a search for $H\to b\bar b$ produced in association with single top quarks / Popov, Andrey (Louvain U.) /CMS Collaboration The CMS collaboration has performed a search for an associated production of Higgs bosons and single top quarks in the $H\to b\bar b$ decay channel.The measurement is challenged by a complex multijet final state and an overwhelming background from top-quark pair production.These proceedings address a particular aspect of the search and describe the procedure deployed to discriminate the signal process from backgrounds..
